FIELD OF THE INVENTION
The present invention generally relates to the fields of optometry and ophthalmology and the performance of eye examinations. More specifically, certain embodiments are directed to systems and methods for enabling customers and other users to obtain eye health examinations and vision examinations through a customer diagnostic center that includes ophthalmic equipment and instruments for performing various tests and procedures pertaining to the customers' eye health and visual ability. According to certain of these embodiments, the customer diagnostic center provides data pertaining to the customer and the tests to a remote practitioner via a network for review and evaluation and receives an eye health report from the remote practitioner to be provided to the customer.
BACKGROUND OF THE INVENTION
In today's age of increased awareness of health monitoring and the importance of early detection and prevention of various medical conditions, disorders and diseases, individuals are often required to make visits to medical practitioners for a range of tests and check-ups. For example, it is generally recommended that individuals make regular visits (e.g., once every year, two years, etc.) to practitioners in connection with the monitoring, diagnosis, and treatment of medical conditions in number of areas, such as checking heart-health, detecting various cancers, and monitoring for certain genetically predisposed disorders.
One area in which there is a particular need for regular visits to a medical professional is in connection with the examination of an individual's eyes. Typically, the examination of a person's eyes involves the performance of one or more tests for monitoring and diagnosing eye health, such as detecting glaucoma and retinal disorders, inspecting the pupil, and measuring corneal sensitivity, and/or tests for evaluating visual ability and acuity, such as determining refractive error and detecting color blindness.
There are a number of important benefits to obtaining eye health examinations and/or vision examinations on a regular and continual basis. For example, as with many other types of medical examinations, regular visits and checkups by an individual enable practitioners to monitor and track the health of the individual's eyes and to detect and diagnose certain disorders, diseases and other changes in the patient's eyes and/or vision. Significantly, this allows for early detection, diagnosis and treatment of many conditions, which, in turn, frequently increases the likelihood that the treatment will be successful. In fact, many disorders and diseases are generally treatable or even preventable when detected and diagnosed in the early stages. Also, it is well known that changes in vision can often occur somewhat suddenly, such as at certain periods in a person's life, and eyesight can deteriorate continually over time. Accordingly, another important benefit to regular eye examinations is that they help to ensure that optical prescriptions for individuals are up to date and as accurate as possible.
Given these and numerous other benefits associated with regular eye examinations, it is not surprising that many well-known optometric and ophthalmologic associations and organizations typically recommend that individuals visit eye care professionals once every one or two years Moreover, the need to receive regular eye examinations is particularly important for certain individuals, including those who have a higher likelihood of suffering from various disorders and diseases based on their demographics or other characteristics, such as age, race, profession, individual and/or family history of diseases or disorders, etc. As a result, it is often recommended that many such individuals receive eye exams at least once a year or on an even more frequent basis.
Additionally, it is well known and widely accepted in the eye care and vision field that, in order to maximize these benefits, the regular examinations received by individuals may be in the form of comprehensive eye examinations. Typically, to be considered comprehensive, such examinations may include certain approved tests and procedures and/or meet certain minimum standards and requirements for testing and diagnosis. In particular, comprehensive eye examinations may include some or all of the following tests and procedures (or tests and procedures of an equivalent nature): (i) objective and subjective refraction and/or other tests to check visual acuity; (ii) examination of the extraocular muscles; (iii) peripheral vision test (e.g., by checking the visual field by confrontation); (iv) examination of the external eye; (v) examination of the pupils; (vi) color vision test; (vii) test for stereopsis for depth perception; (viii) evaluation of central vision field (e.g., using the Amsler grid); (ix) cover test for strabismus; (x) an optical coherency tomography (OCT) scan and/or slit lamp examination using biomicroscopy; (xi) examination of eyelids, conjunctiva, cornea, anterior chamber, iris and lens; (xii) measure eye pressure and/or intraocular pressure; (xiii) imaging of fundus using a retinal camera and examination of macula, vessels, optic nerve, peripheral retina, and vitreous humour. In certain cases, it may also be useful to administer particular types of screenings to individuals for certain diseases or disorders (e.g., glaucoma, macular degeneration or hypertensive retina), such as where there is individual and/or family history of diseases or disorders.
Despite the known importance of regular eye health checkups and vision examinations, many individuals only visit eye care professionals and receive eye examinations on a highly sporadic basis. Other individuals fail to visit an eye care professional at all, or only do so in response to suffering from a medical condition or recognizing a potential problem with their vision. In fact, it is estimated that the average American adult receives an eye examination once every five years or more. Likewise, it is estimated that a large percentage of the individuals in America who require some form of vision correction have the wrong correction or no correction. Moreover, even among the individuals that undergo eye exams on a more frequent basis, the examinations received by these individuals often fail to rise to the level of a comprehensive eye examination. For example, when visiting an eye care professional many individuals may simply receive a vision screening and/or a minimal set of visual acuity tests.
While there are various contributing factors, primary reasons why many individuals fail to regularly undergo eye examinations are based on time, cost, and convenience. Typically, in order to obtain an eye examination, an individual required to expend time and effort to seek out, select and make an appointment with an appropriate eye care professional. In turn, time is spent traveling to and from the practitioner's office, waiting for the practitioner, partaking in discussions with the practitioner and/or nurse or assistant and undergoing the examination. Similarly, from the practitioner's perspective, the number of patients that can be seen and examined are limited by a number of factors, such as the time required to examine each patient, update the patient's records, and prepare equipment. As a result, individuals are frequently forced to visit eye care professionals at inconvenient times and/or travel to other, less conveniently located professionals. Also, in order to maximize the number of patients that can be seen, practitioners may limit the number of tests and procedures and/or the time spent on such tests, thereby reducing the time needed for each patient.
Additionally, the costs associated with visiting a practitioner can dissuade, and even prohibit, many individuals from receiving eye examinations on a regular basis. This can be further compounded by the fact that many individuals lack insurance coverage for such examinations and are required to pay some or all of the costs out of pocket. Thus, making regular visits to an eye care professional can often be a time-consuming, inconvenient and expensive commitment. Accordingly, there is a need for novel approaches to providing eye health examinations and vision examinations that minimize the time and cost required by individuals, and thereby encourage individuals to obtain regular examinations.
There have been some attempts in the past to provide systems that simplify and automate the vision testing and examination process. These prior art systems, however, have exhibited a number of drawbacks and limitations, which have resulted in their failure to be adopted by consumers in any meaningful way. One such drawback is that many of these systems only provide vision screening or visual acuity testing. Similarly, many of these systems are limited to a restricted or incomplete set of procedures and tests and do not allow individuals to obtain a comprehensive eye examination. Another drawback is that many of these systems require an on-site eye care practitioner and/or operator to provide some or all of the examination. Other such systems do not allow for any input or feedback from an eye care practitioner. Yet another drawback is that none of these systems provide a real-time interface between the examinee and a remote practitioner. Still yet another drawback is that many of these systems do not include any functionality for automatically detecting or diagnosing potential disorders, defects or risk factors based on an individual's examination data and/or for automatically generating recommendations and/or referrals.
There is, therefore, a need for an eye testing and evaluation system for providing eye health examinations and vision examinations to individuals. There is also a need for a system that allows individuals to obtain eye health examinations and vision examinations through a user-friendly customer diagnostic center that includes a wide range of ophthalmologic and vision testing equipment. There is further a need for a system which enables individuals to receive a comprehensive eye examination. There is further a need for a system having an automated or semi-automated customer diagnostic center that allows individuals to obtain eye health examinations and vision examinations with little or no on-site assistance.
There is also a need for a system that provides an interface between the customer diagnostic center and a remote eye care practitioner over a network. to enable the practitioner to evaluate an individuals eye health and vision. There is further a need for a system that enables the remote practitioner to evaluate an individuals eye health and vision and provides the individual with eye health reports, prescriptions, diagnoses, and/or recommendations from the remote practitioner. There is still further a need for a system that allows a remote practitioner or offsite technician to control or monitor the ophthalmologic and vision testing equipment and/or the administration of various eye health and vision tests to individuals. There is still further a need for a system that can be accessed by individuals at a wide range of convenient locations. There is still further a need for a system that encourages individuals to obtain eye health examinations and vision examinations on a regular basis by reducing the time and cost required.

According to certain embodiments, the communication of some or all of the data sent to and received from the remote practitioner (e.g., customer examination data and customer evaluation data) may be managed and facilitated by CDC server 20. For example, in response to a customer receiving an eye health examination and/or vision examination at customer diagnostic center 10, CDC server 20 may store various data (e.g., customer data, testing data, etc.) received from customer diagnostic center 10 and manage the delivery of the corresponding customer examination data to the remote practitioner. In certain of these embodiments, CDC server 20 may send the customer examination data to remote practitioner device 30 through any suitable delivery mechanism, such as e-mail, text message, file transfer, etc. Alternatively, or additionally, the remote practitioner may be able to access, view and/or download the customer examination data from CDC server 20, such as by using remote practitioner device 30 to access the customer examination data through a web-based service or similar network-based application hosted by CDC server 20 and/or a client application installed on remote practitioner device 30 that is adapted to connect to CDC server 20.
In turn, the receipt of various data from the remote practitioner may be managed by CDC server 20 in a similar manner. For example, after receiving and reviewing the customer examination data, the remote practitioner may send the customer evaluation data to CDC server 20. In certain embodiments, such as where the customer examination data may be accessed and viewed through a web-based service or client application, the remote practitioner may also be able to generate and/or provide the customer evaluation data through the web-based service or client application. In certain of these embodiments, the web-based service or client application may assist the remote practitioner with the process of creating the customer evaluation data, such as by providing a graphical user interface or the like that allows the remote practitioner to make selections, input, upload and edit various data, and generate various reports. In certain other embodiments, CDC server 20 may receive the customer evaluation data from the remote practitioner through any suitable delivery mechanism, such as email.
According to certain other embodiments, CDC server 20 may facilitate and/or establish a connection between customer diagnostic center 10 and remote practitioner device 30 in order to allow the direct communication of certain data between customer diagnostic center 10 and remote practitioner device 30. In certain of these embodiments, a real-time connection may be established between customer diagnostic center 10 and remote practitioner device 30, which allows the remote practitioner to view and interact with a customer, access and view customer examination data, and/or provide customer evaluation data to the customer in real-time, such as during (or shortly after) the administration of one or more eye health and vision tests. The remote practitioner may also be able to monitor and control certain ophthalmic equipment and instruments and/or the administration of one or more eye health and vision tests in real-time. As an alternative (or in addition), CDC server 20 may establish a real-time connection between customer diagnostic center 10 and a device associated with an offsite technician (e.g., an equipment operator or the remote practitioner's assistant, etc.) for monitoring and/or controlling the equipment and the administration of the tests. The process of establishing connections with and communicating various data to and from various devices associated with remote practitioners and off-site technicians is described in further detail below.
In certain embodiments, CDC server 20 may also manage the communication of certain data to various other systems and devices. For example, as shown in FIG. 1, in certain embodiments, after receiving an eye health examination and/or vision examination through customer diagnostic center 10, customers may be able to access some or all of the data associated with their examination or examination (e.g., an eye health report) from various devices, such as customer device 40 via network 50. Customer device 40 may be any suitable type of computing device that is associated with the customer, such as a personal computer, laptop, tablet, PDA, smartphone, etc. In certain of these embodiments, the data may be delivered and/or made accessible to customers through a web or network based service provided by CDC server 20 or a client application installed on customer device 40 in a similar manner to that described above in connection with communicating with the remote practitioner. In certain embodiments, customers may also be able to view, input and/or update other information, such as their customer data. Additionally, customers who have not yet received an eye health examination or vision examination through customer diagnostic center 10 may be able to enter certain background information and/or create an account in advance, such as to avoid having to provide this information when visiting customer diagnostic center 10.
As another example, CDC server 20 may forward certain data associated with customers and their eye health examinations and/or vision examinations to a third party provider of eye-care and vision related products and services, such as to an optical lab through optical lab server 90 (as shown in FIG. 1) or to an eye care professional (not shown) through network 50. In certain of these embodiments the data may only be sent to a third party provider in response to receiving a request from the customer. In certain other embodiments, CDC server 20 may be configured to automatically deliver certain data to one or more third party providers, such as in response to receiving customer evaluation data from a remote practitioner that includes a recommendation and/or referral for the customer to visit an eye care professional in-person.
Although the foregoing describes various examples in which CDC server 20 manages, facilitates, and/or controls the communication of certain data to one or more devices and systems (e.g., remote practitioner device 30 and customer device 40), these examples are intended to be illustrative, not limiting. It should be understood that these (and various other) communications could be managed, facilitated, and/or controlled by one or more other devices or components included with the eye testing and examination system, and/or various third-party or external systems, devices and components. For example, in certain embodiments, such as where customer diagnostic center 10 incorporates some or all of the functionality associated with CDC server 20 and/or database server 22, customer diagnostic center 10 may send customer examination data directly to remote practitioner device 30 and/or make the data accessible to remote practitioner device 30 via a web or network based service or through a client software application. Likewise, in certain embodiments, customer diagnostic center 10 may establish a real-time connection with remote practitioner device 30 and/or a device associated with an off-site technician, and may manage the communication of data to and from various other systems and devices, such as customer device 40 and/or optical lab server 90.
FIG. 2 is a pictorial diagram of an eye testing and evaluation system in accordance with certain other embodiments. In certain embodiments, the eye testing and evaluation system may include a number of customer diagnostic centers. For example, as shown in FIG. 2, the eye testing and evaluation system may include customer diagnostic centers 10A-10E. In certain embodiments, customer diagnostic centers 10A-10E may be in a form similar to the customer diagnostic centers illustrated and described in connection with FIGS. 1 and 3-5 (e.g., customer diagnostic center 10). In certain other embodiments, some or all of customer diagnostic centers 10A-10E may include a limited set of components and/or provide a limited set of features and functionality. For example, customer diagnostic centers 10A and 10C may be configured to provide customers with vision examinations, customer diagnostic centers 10B and 10D may be configured to provide customers with eye health examinations and customer diagnostic center 10E may be configured to provide customers with vision examinations and eye health examinations. The vision examinations and eye health examinations may include both comprehensive examinations and screenings (e.g., screenings that may be necessitate referral to a specialist for further evaluation). In yet other embodiments, one or more of the customer diagnostic centers may include additional components and/or provide additional features and functionality, such as functionality related to ordering and purchasing eye care and vision products and services.
In certain embodiments, customer diagnostic centers 10A-10E may all be owned, operated and/or maintained by the same party, such as a third party associated with the manufacture and/or servicing of the customer diagnostic centers or a company associated with the sale of various eye care and vision products and services. For example, customer diagnostic centers 10A-10E may each be provided at a retail store or other physical location that is associated with an optician or prescription lens company. In certain other embodiments, customer diagnostic centers 10A-10E may be owned, operated and/or maintained by a number of different third parties. According to certain preferred embodiments, the customer diagnostic centers may be provided at a wide range of locations and environments (e.g., retail stores, department stores, malls, doctor's offices, etc.), thereby making it as convenient as possible for customers to locate and visit a customer diagnostic center and obtain eye health examinations and vision examinations.
In certain embodiments, customer diagnostic centers 10A-10E may interface with a number of CDC servers over one or more networks (such as network 50 shown in FIG. 1). For example, as shown in FIG. 2, customer diagnostic centers 10A and 10B may interface with CDC server 20A, customer diagnostic centers 10C and 10D may interface with CDC server 20B, and customer diagnostic center 10E may interface with CDC server 20C. In certain of these embodiments, CDC servers 20A-20C may manage or control certain operations of customer diagnostic centers 10A-10E, provide various functionality and resources used by customer diagnostic centers 10A-10E, and/or enable or facilitate certain communications between customer diagnostic centers 10A-10E and various other systems and devices, in a similar manner to that of CDC server 20 described above in connection with FIG. 1. In certain embodiments, CDC servers 20A-20C may be provided in the form of separate physical computer servers, or may be provided in the form of virtual servers running on a one or more physical computer servers. In certain other embodiments, the functionality associated with CDC servers 20A-20C may be incorporated with a single CDC server (e.g., CDC server 20 shown in FIG. 1), which interfaces with customer diagnostic centers 10A-10E.
In certain embodiments, such as illustrated in FIG. 2, each CDC server may interface with a subset of the customer diagnostic centers that are provided through the eye testing and evaluation system. For example, each CDC server may be associated with a particular predefined subset of customer diagnostic centers. As another example, a CDC server may be associated with customer diagnostic centers that are located within a specified geographic region (e.g., a city, state, etc.) and/or customer diagnostic centers that are owned or operated by a particular third party (e.g., a prescription lens retailer). In certain other embodiments, a separate CDC server may be included for each customer diagnostic center that is provided through the eye testing and evaluation system (i.e., a one-to-one relationship). Additionally, while FIG. 2 shows each customer diagnostic center interfacing with a single CDC server, in certain embodiments, customer diagnostic centers 10A-10E may be able to interface with multiple CDC servers.
According to certain embodiments, CDC servers 20A-20C may interface with one or more database servers, such as database servers 22A-22C shown in FIG. 2. For example, CDC servers 20A-20C may utilize database servers 22A-22C, respectively, to store, retrieve, and access various data that is generated by, related to, and/or used by the customer diagnostic centers, such as customer data, testing administration data, customer examination data, and customer evaluation data, in a similar manner to that described in connection with FIG. 1. In certain of these embodiments, each CDC server may utilize a separate database server (or servers) to store the data that is associated with the particular customer diagnostic centers that are managed or controlled by the CDC server. In certain other embodiments, a central database server (or group of database servers) may be provided that is accessed and utilized by some or all of the CDC servers. One benefit to the use of a central database is that it enables data associated with a particular customer diagnostic center to be accessed quickly and efficiently at various other customer diagnostic centers, such as where a customer visits a number of customer diagnostic centers at different times.
In certain embodiments, such as where customer examination data and/or other information is provided to a remote practitioner for review and analysis of a customer's eye health or visual ability, customer diagnostic centers 10A-10E and/or CDC servers 20A-20C may communicate with a number of remote practitioners. For example, customer diagnostic centers 10A-10E and/or CDC servers 20A-20C may communicate with remote practitioners through remote practitioner devices 30A-30D, as shown in FIG. 2. In certain of these embodiments, the remote practitioner devices may include a wide range of computing devices, such as remote practitioner workstation 30A, remote practitioner smartphone 30B, remote practitioner laptop 30C and remote practitioner tablet 30D. Remote practitioner devices 30A-30D may include devices that are associated with a particular remote practitioner (e.g., a personal smartphone, PC, or tablet), devices that are associated with a number of remote practitioners (e.g., a workstation or company laptop) and/or a combination of the foregoing.
In certain of embodiments, customer diagnostic centers 10A-10E and/or CDC servers 20A-20C may communicate with remote practitioner devices 30A-30D over one or more networks using any suitable communications mechanisms and/or protocols, such as those described above in connection with FIG. 1. For example, customer diagnostic centers 10A-10E and/or CDC servers 20A-20C may send data to and/or receive data from remote practitioner devices 30A-30D through one or more standard transfer mechanisms (e.g., e-mail). Alternatively, or in addition, customer diagnostic centers 10A-10E and/or CDC servers 20A-20C may provide data to and receive data from the remote practitioners through a client-server framework, such as a web based service hosted by CDC servers 20A-20C and accessed by remote practitioner devices 30A-30D (e.g., via a web browser) or a client application installed on remote practitioner devices 30A-30D that connects to a server application running on CDC servers 20A-20C.
As illustrated in FIG. 2, some or all of the communications and connections between remote practitioner devices 30A-30D and customer diagnostic centers 10A-10E and/or CDC servers 20A-20C may be facilitated by one or more intermediary servers, such as remote practitioner management (RPM) server 24. In certain embodiments, RPM server 24 may simply act as a central gateway or proxy server that provides various interfaces through which data can be communicated to and received from the remote practitioner devices. In certain other embodiments, RPM server 24 may play a more active role and provide various features and functionality associated with managing, controlling and/or tracking the communications and/or connections with the remote practitioner devices. For example, RPM server 24 may keep track of the remote practitioners and/or remote practitioner devices that are associated with the eye testing and evaluation system and/or manage the distribution of data to the remote practitioners. In certain embodiments, the RPM server 24 may maintain a listing of remote practitioners, remote practitioner devices 30, customer diagnostic centers 10 and any other component or individual that is currently connected to the eye testing and evaluation system. The listing may be utilized to establish a connection between a remote practitioner device 30 and a customer diagnostic center 10.
In certain embodiments, RPM server 24 may utilize one or more database servers, such as practitioner database server 26 shown in FIG. 2, to store and access various data pertaining to the remote practitioners and the remote practitioner devices. Among other things, the practitioner data may include certain background information for each remote practitioner (e.g., name, age, qualifications, location, etc.), data indicating one or more remote practitioner devices associated with each remote practitioner and/or data pertaining to one or more communication mechanisms through which data may be delivered to and/or made accessible to the remote practitioners. In turn, RPM server 24 may access and use the practitioner data (or a portion thereof) in a number of manners.
For example, RPM server 24 may use the practitioner data in connection with forwarding data from the CDC servers and/or customer diagnostic centers to remote practitioners, such as to determine how the data should be delivered (e.g., e-mail, through a client application, etc.) and/or where the data should be delivered (e.g., determine one or more remote practitioner devices). Similarly, the practitioner data may be used to confirm whether data should be delivered to a particular remote practitioner (e.g., whether the remote practitioner is currently providing services through the system, connected to the system or whether the remote practitioner has certain required qualifications or expertise). As another example, RPM server 24 may provide some or all of the practitioner data to the CDC servers and/or customer diagnostic centers, such as to allow a customer to view and/or select from one or more remote practitioners, and/or to enable the CDC servers or customer diagnostic centers to determine remote practitioners to communicate with. In certain of these embodiments, the practitioner data may keep track of the customers for which each remote practitioner has reviewed examination data and/or provided eye health reports, optical prescriptions, etc., thereby allowing RPM server 24 (or the CDC servers or customer diagnostic center) to determine whether the data for a current customer can be sent to a remote practitioner that may already be familiar with the customer (e.g., in the case that the remote practitioner previously examined or interacted with the customer).
In certain embodiments, the practitioner data may store data that pertains to the availability and/or status of each remote practitioner. This data may include, for example, information related to a remote practitioner's schedule, the days and/or hours that a remote practitioner is available to review customer examination data through the system, whether the remote practitioner is on vacation, etc. The availability data may be used in various ways to manage the communication of data to the remote practitioners, such as determining whether a particular remote practitioner is able to review customer examination data, and/or providing a list of the currently available remote practitioners to the CDC servers and/or customer diagnostic centers. In certain of these embodiments, such as where a real-time connection is established between customer diagnostic centers and remote practitioners, the availability data may include an indication of whether each remote practitioner is online and/or available for connecting to a customer diagnostic center (e.g., is not already connected to a customer diagnostic center, has a sufficient network connection, is using a supported remote practitioner device, etc.).
Likewise, the practitioner data may include data that is associated with monitoring and tracking the current workload of the remote practitioners through the system (e.g., the number of customers for which each remote practitioner is in the process of reviewing and analyzing examination data). In turn, this data can be used by RPM server 24 to determine and select the remote practitioners who have availability to review examination data associated with additional customers. Alternatively, or additionally, this tracking data may be used to determine or prioritize the remote practitioners that should be assigned customer examination data as it is received, such as by keeping a list of the remote practitioners that is ordered based on how long it has been since customer examination data was provided to each remote practitioner. Accordingly, by monitoring and tracking the workload of the remote practitioners, RPM server 24 is able to distribute the customer examination data to the pool of remote practitioners in a balanced manner, thereby minimizing the amount of time each customer has to wait before receiving customer evaluation data (e.g., eye health report, diagnoses, optical prescriptions, etc.) from a remote practitioner.
According to certain embodiments, some or all of the practitioner data may be obtained, tracked and/or updated on a regular, periodic or real-time basis using various mechanisms. For example, in certain embodiments, RPM server 24 (and/or the CDC servers or customer diagnostic centers) may regularly query the remote practitioners (e.g., by sending an e-mail to the remote practitioners each week) in order to request that the remote practitioners provide and/or update certain information, such as their upcoming schedules or periods of unavailability. In certain other embodiments, such as where the remote practitioners can review and/or respond to customer examination data through a web-based service or client application, the remote practitioners may be prompted to provide and update this information when they access the service or application (e.g., when they login to a website or launch an application on their device, etc.). Similarly, in the case where real-time connections are established between the remote practitioner devices and customer diagnostic centers, RPM server 24 (and/or the CDC servers or customer diagnostic centers) may update certain of this information in real-time, such as by keeping track of whether each remote practitioners is logged in to the system and/or currently connected to a customer diagnostic center. Additionally, or alternatively, some or all of the practitioner data may be obtained, tracked and/or updated based on information received or accessed from third party sources, such as accessing a remote practitioner's work schedule (e.g., from a doctor's office or hospital associated with the remote practitioner) or accessing a scheduling or calendar application on the remote practitioner's device. In certain other embodiments, RPM server 24 may use any other suitable means to obtain and update the practitioner data.
In certain embodiments, the system for providing vision and/or eye health examinations may be provided, at least in part, by a centralized cloud-based system. The cloud-based system may be accessible via a web browser (or other application) and may be compatible across all web platforms and devices. Both remote practitioners and users at customer diagnostic center 10 (and/or from other devices, such as a home computer) may login to the cloud-based system when utilizing the system. The cloud-based system may facilitate the exchange of audio/video streams between remote practitioner devices 30 and customer diagnostic centers 10, and may provide various interfaces for display on remote practitioner devices 30 and devices located at customer diagnostic center 10. For example, interfaces may be provided via remote practitioner device 30 for manipulating and controlling the equipment (e.g., the equipment illustrated in FIGS. 4 and 5) located at customer diagnostic center 10, for transmitting customer evaluation data and/or eye health reports to customer diagnostic centers 10, for saving data to a server, for accessing customers' medical records, for communicating with customer diagnostic centers 10 (e.g., via instant messaging, voice, video or other means), and/or for any other features and functionalities related to administering an eye health or vision examination. Likewise, interfaces may also be provided to devices located at customer diagnostic centers 10 for transmitting examination data to remote practitioner devices 30, for saving data to a server, for accessing medical records, for communicating with remote practitioner devices, and/or for any other features and functionalities related to administering an eye health or vision examination.
Although a particular number of remote practitioner devices, CDC servers and customer diagnostic centers are shown in FIG. 2 for illustrative purposes, it should be understood that the eye testing and evaluation system may include any number of these servers and devices. Similarly, while RPM server 24 and practitioner database server 26 are shown in FIG. 2, in certain embodiments, the functionality associated with RPM server 24 and/or practitioner database server 26 may be any number of servers. In certain other embodiments, some or all of the functionality associated with RPM server 24 and/or practitioner database server 26 may be integrated with one or more of CDC servers 20A-20C and/or customer diagnostic centers 10A-10E.

In addition, as discussed in more detail below, a wide variety of data and information may also be displayed to and received from customers through customer interface 160 in connection with numerous other features and functionality, such as paying for services received through the customer diagnostic centers, requesting data to be forwarded to one or more third parties, viewing, ordering and purchasing eye-care and vision products and services, and/or communicating with remote practitioners and other third parties.
In certain embodiments, customer interface 160 may include various software, applications and programs for managing the output of information to customers and/or assisting customers with the process of inputting and providing data, responses, etc. In certain of these embodiments, these applications may provide customers with a user-friendly graphical user interface that allows the customers to access and view information, input text and other data, and make selections, such as through a touch screen, keyboard, mouse or the like.
According to certain embodiments, customer interface 160 may include an audio response system, which may comprise and utilize various systems, devices, and software, such as speakers, microphones, voice recognition software, text-to-voice software, etc. In certain of these embodiments, the audio response system may be used to output various information and data to and/or receive various inputs, selections and data from the customers in the form of voice and/or other suitable audio data. In certain of these embodiments, the audio response system may be utilized in addition to (or instead of) outputting and receiving some or all of the data through other mechanisms, such as displays, keyboards, etc. For example, the audio response system may be used in connection with the administration of one or more eye health and/or vision tests, such as to ask the customer questions, receive responses and selections from the customer, and/or provide instructions and directions to the customer. In certain of these embodiments, the questions or other audio outputs may be based on a stored set of predefined questions and/or may be selected or determined based on the customer's responses to previous questions or the measurements or results of prior tests or procedures administered to the customer.
In certain embodiments, customer diagnostic center 10 may include network interface 180, as shown in FIG. 3. Network interface 180 may include any known networking devices, computer hardware and software, and/or associated systems and components, that enable customer diagnostic center 10 to send and receive data via one or more networks. In certain of embodiments, network interface 180 may provide interfaces that allow customer diagnostic center 10 to communicate with (and/or connect to) various other systems and devices (e.g., CDC servers, remote practitioner devices, third party retailer systems, etc.) over a wide range of networks (e.g., network 50). In certain of these embodiments, network interface 180 may also (or alternatively) be responsible for facilitating, controlling and/or managing some or all of the communications. For example, network interface 180 may facilitate and/or manage the communication of various data to and from CDC servers (e.g., customer data, testing data and programs, software and firmware updates, etc.), and remote practitioner devices (e.g., customer data, customer examination data, customer evaluation data, etc.).
According to certain embodiments, network interface 180 may include various systems, software and other components that allow for the encryption and encoding of some or all of the communications sent from the customer diagnostic center to be encrypted or encoded prior to transmission (as well as the decryption and decoding of communications received by the customer diagnostic center). For example, customer diagnostic center 10 may encrypt and/or encode all transmissions that include medical data for the customers (e.g., customer examination data, prior test results, etc.), or may encrypt and/or encode all transmissions having any data that is associated with the customers. In certain of these embodiments, the data and/or communications may be encrypted and/or encoded using any know methods and mechanisms.
Although FIG. 3 illustrates a exemplary portion of the systems, devices, and components that may be included in customer diagnostic center 10, in certain embodiments some or all of the customer diagnostic centers provided through the eye system may include various other systems, devices, and components (not shown in FIG. 3). For example, the customer diagnostic centers may include one or more recording devices, systems, and/or associated software (e.g., cameras, video cameras, audio recorders, etc.) that enable the customer diagnostic centers to capture and record various data associated with the administration of the tests and procedures to customers. In certain embodiments, such as where the customer diagnostic centers communicate with a remote practitioner and/or off-site technician, this data may be sent to these individuals along with (or instead of) customer data and/or customer examination data, such as to allow the remote practitioner to view the customers, view or hear responses from the customers, and/or to determine whether certain equipment was setup and operated appropriately and whether one or more tests were administered properly. In certain of these embodiments, such as where a real-time connection is established between the customer diagnostic centers and the remote practitioner devices, the recording system may allow the customer to interact with the remote practitioner in real-time (e.g., through an audio/video conferencing system or the like).
As another example, the customer diagnostic centers may include various payment related devices, systems, and/or software (e.g., credit/debit card readers, devices for depositing cash or checks, etc.) that allow the customer diagnostic center to receive payments from customers, such as in connection with providing customers with eye health examinations, vision examinations, and/or other services (e.g., ordering products and services from third parties). As yet another example, the customer diagnostic centers may include a number of other devices and systems for providing information to customers, such as printers, and/or for allowing customers to upload and input information, such as scanners, card readers, USB key readers, etc.
Additionally, some or all of the components shown in FIG. 3, may be omitted from customer diagnostic centers provided through the eye testing and evaluation system, or may be replaced with one or more other components. For example, in certain embodiments, some or all of the customer diagnostic centers may be implemented without the use of an on-site operator interface, and/or may include only one of vision examination system 150 or eye health examination system 140.
Vision Examination System
FIG. 4 is a block diagram illustrating a portion of a customer diagnostic center having a vision examination system in accordance with certain embodiments. As discussed above, in certain embodiments, some or all of the customer diagnostic centers provided with the eye testing and evaluation system may include a vision examination system. The vision examination system may comprise various ophthalmic devices, equipment and instruments, and other general hardware, mechanical and electronic devices and/or computer software and hardware that is utilized by the customer diagnostic center to provide vision examinations to customers. For example, as shown in FIG. 4, vision examination system 140 may include auto-phoropter 141, lens houser 142, auto refractor 143, lensometer 144, eye chart 145, and vision examination controller 148.
In certain embodiments, auto-phoropter 141 may comprise any suitable type of phoropter and/or other similar device (or a number of such phoropters and devices) that can be used to present powered lenses in front of a customer's eyes. Lens houser 142 may include one or more devices that are used to house and maintain a number of powered lenses and/or allow the lenses that are presented through auto-phoropter 141 to be switched in and out. In certain embodiments, lens houser 142 includes a wide range of powered lenses having different sphere, cylinder and/or axis values. Although, auto-phoropter 141 and lens houser 142 are shown as separate components in FIG. 4, in certain other embodiments, lens houser 142 (or a portion thereof) may be integrated with auto-phoropter 141.
Auto-refractor 143 may include one or more suitable types of refractors and/or similar devices that can be used to measure the refractive error of a customer's eyes. In certain of these embodiments, auto-refractor 143 may allow the system to determine approximate objective optical error specifications for sphere, cylinder and axis for one or both of the customer's eyes and/or measure curvatures in the steepest and flattest meridians of the corneas. In certain embodiments, vision examination system 140 may include an auto-keratometer, which may be integrated with auto-refractor 143, for measuring “K readings” that may be used to determine back or base curvature of a customer's lenses. Lensometer 144 may comprise one or more suitable types of lensometer and/or similar devices that can be used to measure and determine the power of optical lenses that are included in a pair of eye-glasses or contact lenses (e.g., the customer's current glasses). Eye chart 145 may be in the form of one or more charts, images, or the like, that can be presented to customers during various vision examination tests, such as to aid in determining the customer's visual acuity. In certain of these embodiments, eye chart 145 may include one or more physical eye charts and/or virtual eye charts (e.g., charts or images that are displayed on a computer screen or electronic display).
As shown in FIG. 4, in certain embodiments, vision examination system 140 may also include vision examination controller 148, which may comprise one or more processing units, microcontrollers, computing devices, hardware and software, and/or mechanical and electrical devices and components that control the operations of the vision examination equipment. In certain embodiments, vision examination controller 148 may be connected to and/or communicate with equipment controller 130 to allow the vision examination equipment to be monitored and/or controlled by the customer diagnostic center and/or one or more individuals (e.g., on-site operator). In certain other embodiments, vision examination controller 148 (or a portion thereof) may be integrated with equipment controller 130 and/or the vision examination equipment (e.g., auto-phoropter 141, lensometer 144, etc.).
In certain embodiments, some or all of these (and other) components may be used by the customer diagnostic center in connection with administering a variety of tests and procedures to customers, such as in order to measure, capture and/or record data pertaining to a customers' visual acuity and/or visual ability. For example, some or all of these components may be used in order to perform an automated refraction process that allows the refractive error of a customer's eyes to be determined. The following description is intended to demonstrate the type of steps and operations that may be included in an exemplary automated refraction process performed by a customer diagnostic center in accordance with certain embodiments.
In response to a customer requesting a vision examination, the customer diagnostic center may determine a preliminary refractive error or error range for the customer's eyes. In certain embodiments, the preliminary error may be determined based on various data associated with the customer, such as prescriptions or refractive errors associated with one or more prior vision examinations received by the customer (e.g., through a customer diagnostic center and/or from various practitioners) that is retrieved from customer data (e.g., stored in local memory or at a CDC server or database server). Alternatively, or in addition, the customer diagnostic center may use lensometer 144 to determine the preliminary refractive error by measuring the power of the lenses in a current pair of eyeglasses or contact lenses provided by the customer. In certain of these embodiments, the preliminary refractive error may be used in the automated refraction process in various manners, such as to determine a starting point for other tests or calculations or to confirm or check that the process was performed properly (e.g., to check that the ultimate determination for the refractive error does not conflict with or seem highly improbably in light of the customer's prior refractive error). The customer diagnostic center may also (or instead) measure the refractive error of the customer's eyes using auto-refractor 143.
The customer diagnostic center may then use auto-phoropter 141, lens houser 142 and/or eye chart 145 to administer an interactive refraction test to the customer. In certain embodiments, this may include an iterative process in which powered lenses are placed in front of the customer's eyes using auto-phoropter 141 and/or lens houser 142, questions are presented to and responses are received from the customer using the customer interface (e.g., through the audio response system), and based on the customer's responses, the powered lenses are switched with lenses having a different power, and so on. The questions may include asking the customer to read information displayed on eye chart 145 and/or asking the customer whether the displayed information appears clearer or less clear with the current powered lenses. In certain of these embodiments, the questions may be retrieved from a predefined set of stored questions and/or based on the customer's responses to previous questions. This iterative process may continue until one or more conditions or criteria are met, such as receiving a particular combination of responses from the customer, or determining that sufficient data has been acquired through the test.
In certain embodiments, after performing these tests and measurements (or at one or more points during the process) the customer diagnostic center may record and/or store various types of data, such as the questions presented to and responses or inputs received from the customer, the tests, operations and steps performed, the results of the measurements, calculations performed, etc. In turn, some or all of this data may be stored locally and/or sent to a CDC server to update the customer data and other information associated with the customer. The customer diagnostic center may then determine an updated refractive error for the customer's eyes, such as by making various calculations and applying one or more predefined algorithms to the examination data and/or other data (e.g., customer data). In certain embodiments the customer diagnostic center may package and/or format some or all of the examination data and customer data, together with the final refractive error and other information (e.g., potential disorders, defects or conditions detected by the customer diagnostic center based on the examination data), and send the packaged data to a remote practitioner for review and confirmation. In response, the customer diagnostic center may receive customer evaluation data (e.g., revised refractive error, optical prescription, recommendations, referrals to see other practitioners, etc.) from the remote practitioner.
In certain other embodiments, the customer diagnostic center may establish a connection with the remote practitioner prior to, during, or after performing the automated refraction procedure, such as to allow the remote practitioner to monitor and control the tests, view and interact with the customer, review and analyze the examination data, and/or provide the evaluation data in real-time. In yet other embodiments, the customer diagnostic center may automatically generate customer evaluation data based on the updated refractive error, examination data and/or customer data. After generating or receiving the customer evaluation data, the customer diagnostic center may provide the customer evaluation data (or a portion of it) to the customer, such as by displaying information to the customer and/or providing the customer with one or more printed documents (e.g., an optical prescription) at the customer diagnostic center, or sending information to the customer (e.g., via e-mail).
As can be seen from the foregoing, the automated refraction procedure performed through the customer diagnostic center may include both an objective portion (e.g., using auto-refractor 143 to measure the customer's objective refractive error and/or lensometer 144 to measure the power of the customer's current lenses), and a subjective portion (e.g., using auto-phoropter 141, lens houser 142, eye chart 145 and/or an automated voice response system to present powered lenses in front of the customer's eyes and ask the customer questions and receive subjective responses from the customer pertaining to the customer's perceived visual acuity with such powered lenses). In a similar manner, various other vision examination and/or eye health tests and procedures performed by the customer diagnostic center may include both objective and subjective components. One important benefit to using these types of tests is that the accuracy of the tests and the corresponding results is often significantly higher as compared to similar tests that only utilize an objective or subjective process.
The exemplary automated refraction process discussed above is intended to be illustrative, not limiting, and it should be understood that, in certain other embodiments, one or more of the described steps or operations could be removed, reordered, or modified, or could be replaced with one or more other steps or operations, and various other steps and operations may be added to the process. Also, the vision examination system illustrated in FIG. 4 may be used by the customer diagnostic center to perform various other tests and procedures associated with the examination of a customer's vision. Likewise, the vision examination system may be modified, such as by omitting, updating or replacing one or more of the components shown in FIG. 4 and/or including other ophthalmic equipment, devices, instruments, and/or other associated components, in order to incorporate new or update existing vision examination equipment, tests and procedures.
For example, vision examination system 140 may include an electronic visual acuity monitor for allowing the system to perform various tests associated with measuring a customer's visual acuity at longer distances. In certain embodiments, the electronic visual acuity monitor may be used to determine the size of objects at specific distances that are visually perceptible to a customer (e.g., 20/20 or 20/30 size letters or other object). In certain of these embodiments, the electronic visual acuity monitor (or a portion of it) may be integrated with eye chart 145, such as in the form of a Snellen ‘E’ chart in a self-lit visual acuity monitor. In certain embodiments, the electronic visual acuity monitor may be used to administer various tests to measure digital visual acuity data for a customer with and/or without lenses at various distances, based on subjective responses and inputs received from the customer, which can be compared to certain measurement standards. In certain of these embodiments, the measurements and results of such tests may allow the system to assess changes in the customer's vision, such as in response to a new set of lenses or treatments received by the customer (e.g., medicine or surgery).
Eye Health Examination System
FIG. 5 is a block diagram illustrating a portion of a customer diagnostic center having an eye health examination system in accordance with certain embodiments. As discussed above, in certain embodiments, some or all of the customer diagnostic centers provided with the eye testing and evaluation system may include an eye health examination system. The eye health examination system may comprise various ophthalmic devices, equipment and instruments, and other general hardware, mechanical and electronic devices and/or computer software and hardware that is utilized by the customer diagnostic center to provide eye health examinations to customers. For example, as shown in FIG. 5, eye health examination system 150 may include digital imager 151, biomicroscope 152, retinal camera 153, tonometer 154, visual field instruments 155, and eye health examination controller 158.
In certain embodiments, digital imager 151 may comprise any suitable type of digital imaging device, such as a camera, video-camera, sonar imager, infrared imager, or other similar digital imager (or a number of such devices) that can be used to capture, record and/or generate digital images of a customer. For example, digital imager 151 may be used to obtain full facial images of a customer, and/or various proportionate, to-scale, images of the customer's eyes, pupils, face, or head (e.g., a full facial image). Biomicroscope 152 may be in the form of any suitable type of microscope or microscopes that are used to magnify the view of the anterior portion of a person's eyes (e.g., the first third of a person's total eye length). In certain embodiments, biomicroscope 152 and/or digital imager 151 may be used to detect, and capture images related to, various tissue enhancements (e.g. from the tear layer, cornea, aqueous/anterior chamber, lens, and/or posterior chamber).
In certain embodiments, retinal camera 153 may comprise any suitable type of camera or other like device that allows for enhanced viewing and/or digital imaging of the rear portion of a person's eyes (e.g., the back two third's of a person's total eye length). For example, retinal camera 153 may be used to detect, and capture images related to, the vitreous, choroids, retina, macula, and/or optic nerve of a person's eyes. A tonometer 154 may also be used. Tonometer 154 may include any suitable device or device that can be used to measure the intraocular pressure of a person's eyes, such as to detect, diagnose, and/or evaluate the possibility of glaucoma. In certain of these embodiments, for example, tonometer 154 may allow intraocular pressure to be determined in millimeters of mercury (mmHG), such as by detecting the degree of indentation (e.g., resistance) of a probe at a ninety degree angle flat to the center of a person's cornea and using this measurement to calculate mmHG based on one or more predefined formulas.
Eye health examination system 150 may also include various visual field instruments, such as visual field instruments 155 illustrated in FIG. 5. In certain embodiments, visual field instruments 155 may comprise one or more instruments and devices that can be used to detect and measure visual sensitivity and/or acuity in a person's peripheral view (e.g., things surrounding an object upon which a person's vision is primarily fixed or focused). For example, in certain of these embodiments, visual field instruments 155 may be used to flash various visual stimuli of different light-candle strengths in a customer's periphery while the customer's vision is focused on an object that is straight-ahead. In turn, such tests can determine the existence of various defective fields of vision, such as patterns of non-discernable vision within a world-view having four, equal and symmetric quadrants (e.g., a person's blind spot, where there are no rods and cones), which can be used to detect, diagnose, and/or evaluate certain conditions and disorders (e.g., advancing glaucoma, detached retina, tumors, diabetic retinopathy, or retinitis pigmentosa).
As shown in FIG. 5, in certain embodiments, eye health examination system 150 may also include eye health examination controller 158, which may comprise one or more processing units, microcontrollers, computing devices, hardware and software, and/or mechanical and electrical devices and components that control the operations of the eye health examination equipment. In certain embodiments, eye health examination controller 158 may be connected to and/or communicate with equipment controller 130 to allow the eye health examination equipment to be monitored and/or controlled by the customer diagnostic center and/or one or more individuals (e.g., on-site operator). In certain other embodiments, eye health examination controller 158 (or a portion thereof) may be integrated with equipment controller 130 and/or the eye health examination equipment (e.g., digital imager 151, tonometer 154, etc.).
In certain embodiments, some or all of these (and other) components may be used by the customer diagnostic center in connection with administering a variety of tests and procedures to customers associated with evaluating the customers' eye health. For example, the customer diagnostic center may use some or all of the eye health examination equipment to measure, capture and record customer examination data pertaining to a customer's eye health, process, analyze and evaluate the customer examination data, package and deliver the customer examination data to a remote practitioner for review, receive customer evaluation data from the remote practitioner and/or provide an eye health report to the customer, in a similar manner to the automate refraction process described above.
The following provides certain examples of ophthalmic equipment, devices, instruments, and components, as well as tests and procedures that may be incorporated with the eye health examination system and offered to customers through the customer diagnostic centers in accordance with certain embodiments. It should be understood that the particular equipment and tests described below are intended to be exemplary in nature, not exhaustive, and various other equipment and tests may be used in connection with the eye health examination system, corresponding arrangements and systems, devices and methods described herein. For example, like the vision examination equipment discussed above, the eye health examination system may be modified, such as by omitting, updating or replacing one or more of the components shown in FIG. 5 and/or including numerous other types of ophthalmic equipment, devices, instruments, and/or other associated components. As another example, the eye health examination system may be periodically updated and/or expanded in order to incorporate new or modify existing eye heath examination equipment, tests and procedures, thereby providing customers with a wide range of the most up-to-date equipment, tests and procedures associated with examining eye health.
In certain embodiments, the eye health examination system may include one or more of the following ophthalmic devices, instruments and equipment and/or may utilize one or more of the following tests and procedures in connection with providing customers with eye health examinations through the customer diagnostic centers:

Varying Levels of Automation and Assistance

    
    


As mentioned above, the eye testing and evaluation system may be implemented using different levels of automation and/or different types of assistance from on-site and/or remote individuals. The following describes a number of exemplary implementations having varying degrees of assistance and automation, in accordance with certain embodiments
In certain embodiments, for example, the system (or a portion thereof) may be configured to be fully automated, thereby allowing customers to obtain vision examinations and/or eye health examinations at a customer diagnostic center with no assistance from others. In certain of these embodiments, the customer diagnostic centers may utilize and execute software applications, programs and routines that are designed to obtain various information from the customers through the customer interface (e.g., customer data) and determine one or more vision examination and/or eye health examination tests and procedures to administer to the customers (e.g., based on the customers' data and/or selections received from the customer regarding desired services). Likewise, the customer diagnostic centers may utilize and execute software in connection with administering one or more tests to the customer, such as programs that enable the customer diagnostic centers to control and operate the ophthalmic equipment, devices and related components, output instructions, questions, testing data and other information to customers, and/or receive and record responses and inputs from the customers, measurements, readings, and other data resulting from administering the tests and procedures. In turn, after administering the tests and procedures (or during such administration), the customer diagnostic centers may process and analyze the data captured and recorded through the tests, and/or other data (e.g., customer data), using various algorithms, metrics and software in order to automatically evaluate the customers' vision and/or eye health. In certain of these embodiments, the customer diagnostic centers may also utilize and execute various software for auto-generating one or more reports, documents, and the like pertaining to the customers' vision and/or eye health (e.g., eye-health reports, prescriptions, recommendations, referrals, etc.) that can be output and/or provided to the customers.
In certain embodiments, the system (or a portion thereof) may be configured to enable on-site operators (e.g., operators, technicians, or assistants at the sites where the customer diagnostic centers are located) to facilitate and assist customers with one or more aspects of the vision examinations, eye-health examinations, and/or other services, features and functionality provided through the customer diagnostic centers. In certain of these embodiments, for example, the on-site operators may simply assist customers with one or more processes associated with the use of the customer diagnostic centers, such as creating an account, choosing desired services, printing out an eye health or vision report, forwarding data to third parties, etc. As another example, the on-site operators may assist and guide customers during the administration of various tests and procedures, such as by helping customers assume the required positions and answer or respond to certain questions or other data output during the tests. In certain of these embodiments, the on-site operators may provide assistance to customers on an as-needed or as-desired basis, such as in response to a customer selecting an option or otherwise indicating a desire for on-site help.
In certain of these embodiments, the on-site operators may monitor and/or control the ophthalmic equipment and devices (e.g., through an on-site operator interface), such as during one or more tests and procedures to ensure proper administration, and/or before and after the tests and procedures to initialize, setup and/or reset the equipment. Likewise, in certain of these embodiments, the on-site operators may also (or instead) monitor and control the administration of one or more tests, such as by selecting and/or modifying the questions or outputs presented to the customers based on previous responses from the customers and/or test results. In certain other embodiments, some or all of the assistance provided by, and functionality associated with, the on-site operators may be provided by one or more remote operators (e.g., a technician located at a remote call center or an assistant associated with a remote practitioner).
According to certain embodiments, the system (or a portion thereof) may be configured to enable remote practitioners (e.g., practitioners who are not at the sites where the customer diagnostic centers are located) to facilitate and assist customers with one or more aspects of the vision examinations, eye-health examinations, and/or other services, features and functionality provided through the customer diagnostic centers. For example, in certain preferred embodiments, when a customer receives a vision examination and/or eye health examination through a customer diagnostic center, various data associated with the customer and one or more of the tests and procedures administered to the customer is provided to a remote practitioner (e.g., via a remote practitioner device) to allow the remote practitioner to confirm, evaluate and diagnose the customer's visual ability and/or eye health and/or create a vision and/or eye health report (or similar evaluation) to be provided to the customer.
In certain of these embodiments, this process may occur asynchronously. In other words, after the customer has received the vision examination and/or eye health examination, the system may deliver the customer data and customer examination data to the remote practitioner (or make such data available to the remote practitioner through a web-based service and/or software application installed on the remote practitioner device). At some later time, the remote practitioner may then review and analyze the data, diagnose and confirm various aspects of the customer's vision and eye health, and generate and/or send back customer evaluation data (e.g., vision report, eye health report, optical prescriptions, etc.), which can then be sent or made accessible to the customer (e.g., at a customer diagnostic center, at a device associated with the customer, etc.).
In certain other embodiments, assistance from remote practitioners may occur synchronously. In certain of these embodiments, when a customer requests a vision examination and/or eye health examination through a customer diagnostic center (or at some point during the examination or examination process), the system may be configured to establish a real-time connection to a remote practitioner. As a result, this allows the remote practitioner to review and evaluate the customer examination data and provide evaluations and reports to the customer in real-time or near real-time. Additionally, or as an alternative, the remote practitioner may be able to monitor and control the ophthalmic equipment and instruments and/or the administration of the tests and procedures to the customer, in a similar manner to that described above for the on-site (or remote) operator, through the real-time connection with the customer diagnostic center.
For example, in certain embodiments, some or all of the ophthalmic equipment and instruments at the customer diagnostic center may be connected to a personal computer running Windows or any other suitable operating system and having a client application installed that provides an interface to (e.g., sends commands to and receives data from) the equipment. The client application may be any suitable application capable of providing a remote interface to the ophthalmic equipment, such as the Eyelogic touchscreen-enabled Windows application available from Eyelogic Systems, Inc. In certain embodiments, the client application may store various data (e.g., in a database stored in local memory at the customer diagnostic center), including data received from the ophthalmic equipment and/or customers. In certain of these embodiments, such as where the personal computer and/or customer diagnostic center includes various recording devices (e.g., a video recorder, microphone, etc.) the client application may record and/or store the vision examination and/or eye health examination session (e.g., the interactions with the customer, tests administered to the customer, etc.).
In certain embodiments, the client application and/or personal computer may be connected to a tele-presence system, which may be any suitable system for establishing a real-time connection with, and routing or streaming various data to and from a remote agent (e.g., a remote practitioner via a remote practitioner device). For example, the client application and/or personal computer may be connected to a tele-presence client framework or endpoint, such as the VidyoDesktop software application available from Vidyo, Inc. The endpoint may connect to a tele-presence server and/or server framework, such as a VidyoRouter server available from Vidyo, Inc, via any suitable network and/or network protocol (e.g., the Internet and/or Session Initiation Protocol). In certain of these embodiments, the tele-presence server and/or server framework may be integrated with and/or run on one or more CDC servers or RPM servers included with the eye testing and evaluation system (such as CDC servers 20 and 20a-20c and/or RPM server 24 shown and described above in connection with FIGS. 1 and 2).
According to certain embodiments, the tele-presence server and/or server framework may be configured to route the examination and/or examination session to an available remote practitioner, such as via a CTS-500 Endpoint or other suitable tele-presence client framework or endpoint associated with the remote practitioner (e.g., an endpoint integrated with or connected to a remote practitioner device). As a result, data associated with the examination and/or examination session can be streamed or otherwise delivered to the remote practitioner in real-time. In certain of these embodiments, the endpoint associated with the remote practitioner may be configured to send various data back to the endpoint associated with the customer diagnostic center, thereby enabling two-way communication between the remote practitioner and the customer. For example, the remote practitioner may send back commands for controlling the ophthalmic equipment and/or the administration of the tests, audio/video data to be output to the customer (e.g., instructions, questions, guidance, etc.) and/or evaluation data pertaining to the customer's vision and/or eye health (e.g., vision and/or eye health reports, prescriptions, recommendations, referrals, etc.).
In certain other embodiments, the tele-presence system may enable real-time teleconferencing and video conferencing to be established without the need for specialized networks, endpoints, and/or other hardware (e.g., dedicated cameras, microphones, monitors, firmware, etc.). For example, the system may utilize a centralized teleconferencing infrastructure, which enables and manages conferencing between software endpoints (e.g., devices having certain software installed). In certain embodiments, this centralized conferencing architecture may be provided and managed by a separate service provided, such as the VidyoRouter service provided by Vidyo, Inc. Importantly, the use of this type of centralized architecture allows for the conferencing functions to be performed at the customer diagnostic centers via the same hardware (e.g., computer, monitor, etc.) used for controlling the ophthalmic equipment, interfacing with the customers, and/or administering the vision tests and eye examinations. In certain of these embodiments, the conferencing software that is installed and executed at the customer diagnostic centers and/or remote practitioner devices may be customized in any suitable manner, such as to display or present various data to a customer prior to, or during, a conference (e.g., customer data, prior examination data, introductory videos, logos, etc.).
According to certain embodiments, such as where a real-time conference is established between a customer and remote practitioner during the administration of a vision and/or eye health examination, the examination and conference (or a portion thereof) may be recorded and stored, such as at the centralized teleconferencing system. In certain of these embodiments, these stored recordings may be accessible to one or more individuals, such as the customer, remote practitioner, and/or other practitioners. For example, the remote practitioner may wish to replay some or all of the recorded examination session in connection with reviewing and analyzing the customer's examination data and/or providing a prescription or eye health report. As another example, the recorded examination session may be provided to another practitioner for review, such as in the case where the customer is referred to a specialist practitioner for further or follow-up testing, diagnosis and/or treatment.
As shown by the foregoing discussion, the ability for customers who are receiving vision examinations and/or eye health examinations at a customer diagnostic center to connect to and interface with remote practitioners in real-time provides a number of important benefits. One such benefit is that it enables the remote practitioners to “touch and feel” the customers, such as by interacting with and interrogating the customers, thereby allowing the remote practitioners to provide a more meaningful and accurate evaluation of the customers' vision and eye health. Another such benefit is that it allows customers to receive vision examinations and/or eye health examinations in virtually the same manner as an in-person screening or examination, while significantly reducing the time, inconvenience and expense associated with visiting a practitioner's office to obtain the in-person screening or examination.
In addition, by utilizing one or more of the systems and methods for implementing various degrees of automation and/or assistance at the customer diagnostic centers, the eye testing and evaluation system enables a great deal of flexibility and customizability. For example, certain customer diagnostic centers could be configured to provide fully-automated vision examinations and/or eye health examinations or examinations with limited on-site assistance, thereby allowing customers to obtain examinations with little or no assistance and minimizing the corresponding time and cost required. In certain embodiments, these fully-automated (or minimally assisted) vision examinations and/or eye health examinations could be in the form of limited or partial examinations (e.g., examinations having a limited set of tests and procedures that are capable of being automatically processed and evaluated by the system). In turn, some or all of these customer diagnostic centers (or others) may give customers the option of receiving a more extensive or comprehensive vision examination and/or eye health examination (e.g., at a higher cost), such as examinations that require the assistance of a remote practitioner.
Vision and Eye Health Evaluations
As mentioned above, in connection with a customer receiving a vision examination and/or eye health examination through a customer diagnostic center, the customer diagnostic center and/or eye testing and evaluation system may generate and/or provide the customer with customer evaluation data pertaining to the customer's vision and/or eye health, such as one or more reports, charts, documents, summaries, test results, recommendations, referrals, treatments, etc. In certain of these embodiments, some or all of the customer evaluation data may be automatically generated by the customer diagnostic center and/or eye testing and evaluation system, such as by applying various software and algorithms to, and otherwise processing, the data associated with administering the tests and procedures to the customer and/or other data (e.g., customer data). Alternatively, or in addition, some or all of the customer evaluation data may be received (or be based on data received) from a remote practitioner, such as in response to providing the customer examination data and customer data to the remote practitioner for review and analysis.
In certain embodiments, such as where a customer receives a vision examination through a customer diagnostic center, the customer evaluation data may include vision evaluation data, such as an optical prescription, set of optical specifications and/or an order for eyeglasses and/or contact lenses (e.g., FDA Class I, OTC medical devices). In certain of these embodiments, such as where the customer evaluation data is received (or based on data received) from a remote practitioner, the optical prescription (and/or optical specifications or order) may be signed by the remote practitioner (e.g., using an electronic signature or similar mechanism) and dated. The optical prescription may or may not indicate an expiration date and/or may indicate to the customer that the optical prescription can be filled by the optical dispenser of the customer's choice.
In certain embodiments, the vision evaluation data may include data and information pertaining to one or more parameters associated with the customer's visual acuity, such as the parameters used to determine the refractive error of the customer's eyes. For example, the vision evaluation data may include the strengths or curvatures in degrees and/or Diopters (e.g., converted from millimeters of radius of curvature into Dioptric strength power) for one or more components of visual acuity, such as (1) Sphere in Diopters (e.g., in connection with simple myopia/nearsightedness and hyperopia/farsightedness); (2) Cylinder Power in Diopters (e.g., in connection with astigmatism), (3) Axis of Cylinder in degrees from 0 to 180 (e.g., in connection with astigmatism); and/or (4) another Sphere in Diopters, such as bifocal power pertaining to additional correction needed for reading (e.g., in connection with presbyopia, typically present in individuals over 45). In certain embodiments, the vision evaluation data may include information that indicates the corrected and/or un-corrected visual acuities for the customer's eyes, which may include each eye separately, e.g. 20/40 in the left eye at distance, and/or for the two eyes together. In certain of these embodiments, the vision evaluation data may include an explanation for such visual acuities (e.g. in order for a person with 20/40 vision to see what someone with normal 20/20 vision sees at 40 feet distance, the person with 20/40 vision must be 20 feet away from the same object).
In addition to (or instead of) the optical prescription, the vision evaluation data may include a vision report that provides information concerning any specific vision or refractive disorders or conditions that were detected and/or diagnosed through the vision examination. For example, the vision report may indicate whether or not the customer has certain vision disorders or conditions, such as simple myopia; simple hyperopia; mixed compound astigmatism, hyperopic astigmatism, myopic astigmatism, and/or presbyopia. If any such vision disorders or conditions were detected and/or diagnosed, the vision report may include additional information pertaining to the disorder, such as a general description, recommended treatment, etc. In certain of these embodiments, if one or more particular types of disorders or conditions are detected, the vision report and/or vision evaluation data may include a referral for the customer to visit a practitioner in-person.
According to certain embodiments, such as where a customer receives an eye health examination through a customer diagnostic center, the customer evaluation data may include eye health evaluation data. In certain of these embodiments, the eye health evaluation data may include an eye health report, in a similar manner to the vision report described above. For example, the eye health report may include various data and information that indicates whether the customer's eyes were found to be normal, healthy and/or functioning properly. In certain of these embodiments, the eye health report may indicate whether or not the customer has certain eye disorders or conditions, such as glaucoma, corneal defects, cataracts, color blindness, etc. and may include additional information pertaining to any such disorder or condition that has been detected and/or diagnosed.
In certain embodiments, when one or more eye disorders or conditions have been detected and/or diagnosed, the eye health evaluation data may indicate whether there is a need for the customer to seek further evaluation, testing and/or treatment through an in-person consultation with an eye health practitioner (e.g., an eye surgeon or other specialist). In certain embodiments, such as where the customer examination data is provided to a remote practitioner for review, the need for further in-person evaluation may be based on determinations or recommendations received from the remote practitioner. Alternatively, or additionally, the system may be configured to automatically detect and/or flag certain examination data or results as indicating a potential need for the customer to seek further evaluation (as described in more detail below). In certain embodiments, the eye health evaluation data may include referrals for the customer to see one or more particular eye health practitioners. In certain of these embodiments, the eye health report may indicate that the referral is urgent and/or mandatory, such as in order to prevent or reduce the risk of permanent vision loss.
According to certain embodiments, the vision evaluation data and/or eye health evaluation data may include one or more recommendations for the customer pertaining to future vision examinations and/or eye health examinations. For example, the vision evaluation data and/or eye health evaluation data may indicate a recommendation for how often the customer should obtain vision examinations and/or eye health examinations (e.g., once a year, once every two years, etc.). In certain embodiments, these recommendations may be based on various customer data (e.g., the customer's age, ethnicity, sex, vision/eye health, individual and family medical history, length of time since the customer's previous examination), and/or risk profiles and similar information provided by various well-known vision and eye health organizations (e.g., the American Academy of Ophthalmology). Likewise, in certain embodiments, the urgency of other recommendations (e.g., referrals to see other practitioners) may be determined in a similar manner. In certain embodiments, the vision evaluation data and/or eye health evaluation data may also include specific diagnoses and/or indicate an actual or suspected condition of a customer's eyes (e.g., whether a customer has healthy eyes or is suspected of having an eye disease, abnormality or other condition).
While the foregoing discussion describes certain types of information that may be included in the customer evaluation data provided to customers who receive vision examinations and/or eye health examinations through the customer diagnostic centers, it should be understood that the particular types of information described are intended to be exemplary, not exhaustive, and various other types of information could easily be included and/or utilized instead of some or all of the information described above. Similarly, although the vision evaluation data and eye health evaluation data are described separately in the discussion above, it should be understood that, in certain embodiments, some or all of the data and information associated with the vision evaluation data and eye health evaluation data may be combined or integrated. For example, in certain embodiments, such as where the customer receives both a vision examination and eye health examination or where the eye health examination incorporates one or more tests associated with vision examination, the customer evaluation data may include a combined vision/eye health report having some or all of the information associated with the vision evaluation data and eye health evaluation data described above.
In certain embodiments, customers may be able to access the customer evaluation data (or a portion thereof) through the customer diagnostic centers. In certain of these embodiments, such as where the vision examination and/or eye health examination is fully automated (or only involves assistance from an on-site operator) or where a real-time connection is established with a remote practitioner, the customer evaluation data may be provided to the customer at the customer diagnostic center (e.g., displayed on one or more screens) during and/or shortly after the customer receives the vision examination and/or eye health examination. Alternatively (or in addition), the customer may be able to access the customer evaluation data by returning to the same customer diagnostic center (and/or one or more other customer diagnostic centers) at a later time. In certain embodiments, the customer may be able to print out some or all of the customer evaluation data (e.g., an optical prescription or referral) using one or more printers provided at the customer diagnostic center.
According to certain embodiments, the customer evaluation data (or a portion thereof) may be sent and/or made accessible to the customers through various other systems and devices, such as one or more personal computing devices associated with the customers. For example, the customer evaluation data may be sent via e-mail or any other suitable delivery mechanism. As another example, customers may be able to access the customer evaluation data from a wide range of computing devices, such as by logging into a web-based service or application provided by the customer diagnostic center and/or eye testing and evaluation system and/or through a software application (e.g., client application, mobile app, etc.) installed on the customers' devices. In a similar manner, the customers may be able to instruct the customer diagnostic center and/or eye testing and evaluation system to forward some or all of the customer evaluation data to various third parties and/or third party systems, such as an external practitioner, optical lens lab, or third party provider of vision and eye care products and/or services. In certain of these embodiments, the customer evaluation data may be sent to the customer and/or one or more third parties automatically or only in response to a request by the customer. In certain embodiments, the customer evaluation data may be conveyed to the customer over a telephone. For example, a customer who requests to speak with a practitioner may provide a telephone number to enable the practitioner to call the customer at a convenient time.
Data Analysis for Diagnosis and Risk Prediction
In accordance with certain embodiments, such as those illustrated and described in connection with FIGS. 1-3, the customer diagnostic centers and/or other components of the eye testing and evaluation system (e.g., CDC servers, database servers, etc.) may store and/or update a wide range of data in connection with providing vision examinations and/or eye health examinations to customers. The eye testing and evaluation system may store and/or update various customer data (e.g., background and demographical data, prior vision examination and/or eye examination results, individual and family medical history, and other characteristics and preferences) associated with the customers. Similarly, the eye testing and evaluation system may store and/or update customer examination data (e.g., customer inputs and responses, instrument measurements, tests and procedures performed, etc.), customer evaluation data (e.g., reports, prescriptions, recommendations, referrals, digital images and other imaging data, etc., generated by the system and/or received from remote practitioners) and/or other types of data associated with the vision examinations and/or eye health evaluations provided to customers through the customer diagnostic centers.
In certain embodiments, the eye testing and evaluation system may store and/or update testing analytics data associated with reviewing, analyzing and processing the customer examination data and/or customer data, such as one or more algorithms and formulas (e.g., to calculate refractive error) and/or various standards, norms, and metrics (e.g., normal or acceptable ranges for certain parameters) that may be applied to the measurements or test results and/or otherwise utilized in connection with detecting or diagnosing various disorders, defects and conditions and evaluating the customers' vision and eye health. Additionally (or alternatively), the eye testing and evaluation system may store and/or update risk prediction data pertaining to various risk factors, risk profiles, correlations and similar information that is associated with vision and eye related disorders, defects and conditions that are more likely to occur in certain groups of individuals.
In certain of these embodiments, the risk prediction data may include risk factors and the like that are based on a person's background (e.g., welders are more prone to have corneal scars that can cause irreversible loss of vision), ethnicity (e.g., Hispanic Americans are more prone by 20% to acquire glaucoma, and African Americans are 40% more prone to acquire glaucoma, as compared to Caucasian Americans), income (e.g., lower income families typically have less frequent eye exams and refractions, and less primary medical health care, and are more prone to irreversible vision caused by diabetes and hypertension), prior medical history (e.g., individuals with pre-existing hypertension, diabetes, or history of eye disease and/or disorders, eye surgeries, etc., are more prone to certain systemic eye disorders and syndromes, such as syphilis, Bell's Palsy, shingles, etc.), age (e.g., individuals over sixty are more prone to certain age related eye diseases (AREDS), such as cataracts, glaucoma, diabetic retinopahy, macular degeneration, etc.).
According to certain embodiments, some or all of this data (and various other data) may be utilized by the eye testing and evaluation system in a number of different ways. In certain embodiments, the eye testing and evaluation system may use this data to determine whether customers have a higher risk for various vision and eye related disorders, defects and/or conditions. For example, in response to receiving new or updated customer data (and/or other data) from a customer, the customer diagnostic center and/or eye testing and evaluation system may compare the customer data to the prediction data to determine whether the customer's demographics, characteristics, etc. match any risk profiles or factors in the prediction data. In certain of these embodiments, the eye testing and evaluation system may create and store an individual risk profile for new customers that includes a list of any high-risk disorders, defects, and/or conditions identified for the customer (e.g., prescreen the new customers) and/or update the individual risk profile when additional or updated customer data is received.
In turn, the individual risk profile (or similar data) could be included with the customer examination data for the customer that is sent to a remote practitioner (e.g., to assist the remote practitioner's review and evaluation) and/or used to select, modify and/or tailor tests and procedures administered to the customer and various recommendations provided to the customer. In certain of these embodiments, the eye testing and evaluation system may use the individual risk profiles and/or other data (e.g., customer data and customer evaluation data) to create and update a customized testing plan for a customer. For example, the customized testing plan may include one or more customized vision examinations and eye health examinations (e.g., specifying a particular group of tests and procedures to be administered), a recommended schedule for receiving such vision examinations and eye health examinations, recommended actions, medicines or treatments, and/or referrals to see one or more eye care practitioners in-person (e.g., on a one-time and/or periodic basis).
In certain embodiments, the eye testing and evaluation system may use some or all of the stored data described above in connection with evaluating the customer examination data and other data associated with administering vision examinations and/or eye health examinations to customers through the customer diagnostic centers. For example, the eye testing and evaluation system may process and analyze the customer examination data based on the testing analytics data, such as to automatically calculate various parameters using predefined formulas and/or detect and diagnose certain disorders, defects and conditions by comparing the customer examination data to one or more standards (e.g., normal or acceptable ranges or results). In certain embodiments, the system may utilize software to analyze images or other digital scanning data to diagnosis and/or risk prevention purposes. For example, images or scanning data associated with the ganglion cell layer may be analyzed by the software for detecting or preventing chronic glaucoma. In certain of these embodiments, such as where the customer examination data is sent to remote practitioners, the eye testing and evaluation system may instead (or in addition) use the testing analytics data to pre-process and package the customer examination data before providing it to the remote practitioner. For example, in connection with measuring or calculating a particular parameter (e.g., intraocular pressure) the eye testing and evaluation system may create a chart or graph that shows the parameter for the customer in relation to an acceptable range associated with the parameter. Importantly, pre-processing and packaging the customer examination data that is provided to remote practitioners makes it easier and more efficient for remote practitioners to review the data and/or confirm the results, thereby reducing the time associated with evaluating and providing reports to each customer.
In certain embodiments, the eye testing and evaluation system may use some or all of the stored data described above to track and evaluate the customers' vision and/or eye health over time. For example, when a customer receives a vision examination and/or eye health examination through a customer diagnostic center, the examination data and/or evaluation data may be compared with data for previous vision examinations, eye health examinations and other similar tests received by the customer (e.g., data associated with previous tests received through a customer diagnostic center, from an external practitioner, or a combination thereof). In certain of these embodiments, the eye testing and evaluation system may generate and/or update various charts, graphs, images, summaries, etc. using the current and previous examination and/or evaluation data, such as to show the progression of one or more parameters, defects, disorders, and/or conditions. For example, after a customer receives a vision examination, the eye testing and evaluation system may create or update a chart that illustrates the changes in the refractive error of the customer's eyes over a specified period. In certain embodiments, these charts, graphs, and/or other tracking data associated with the progression of the customer's vision and/or eye health may be included with the customer examination data that is sent to the remote practitioners in order to assist the remote practitioners in making an informed evaluation and diagnosis.
In turn, by keeping track of customers' vision and/or eye health over time, the eye testing and evaluation system can determine whether a treatment previously prescribed to the customer is working (e.g., whether there has been any improvement or change in a defect or condition being treated), and/or evaluate the outcome of a surgery, operation or procedure previously performed on the customer. Similarly, the eye testing and evaluation system may use the tracking data in connection with detecting and/or diagnosing certain disorders, defects and/or conditions and/or determining whether a customer should be referred to one or more external eye care practitioners. For example, if the eye testing and evaluation system detects that a customer's visual acuity is worsening or not improving despite the use of refractive lenses, this may be a strong indication that the customer has a medical anomaly, disorder or disease (e.g., optic nerve inflammation or infection, amblyopia, cataracts, etc.) and the system may refer the customer to an eye-care practitioner or specialist (e.g., a cataract specialist).
According to certain embodiments, the eye testing and evaluation system may use some or all of the stored data described above to tweak or modify certain existing risk factors, risk profiles, standards, correlations etc. and/or identify new risk factors. For example, the eye testing and evaluation system may analyze the customer data, customer examination data and/or customer evaluation data to search for potential correlations between various parameters (e.g., female Asian Americans have a 30% higher risk of developing cataracts). Similarly, the eye testing and evaluation system may analyze this data to confirm the accuracy of existing risk factors and correlations and/or various standards and norms (e.g., normal ranges for parameters). In turn, as customer data and examination and evaluation data is continuously collected, compiled and processed by the system, these risk factors, correlations and/or standards can be periodically updated to reflect the data.
Exemplary Method for Providing an Eye Testing and Evaluation Service
FIG. 6 is a flow chart illustrating an exemplary method 600 for administering an eye testing and evaluation service in accordance with certain embodiments of the present invention. Initially, one or more tests associated with an eye health examination and/or vision examination are provided to a customer (step 610). In certain embodiments, the one or more tests may be administered at a customer diagnostic center. Next, customer examination data relating to the eye health examination and/or vision examination is generated (step 620). The customer examination data may include any data associated with the customer and any data that enables or assists a remote practitioner to evaluate the customer's eye health and visual ability, detect and diagnose certain disorders, defects and conditions and/or confirm that one or more of the tests and procedures were administered correctly. In certain embodiments, the customer examination data may include data associated with the customer (e.g., the customer's name, age, gender, race, medical history, prior test results, etc.) and data associated with one or more of the tests administered to the customer (e.g., responses, inputs and selections from the customer, instrument measurements and readings, test results, etc.). In certain embodiments, the customer examination data may include a live video stream or video recording of the eye health examination and/or vision examination that was provided to a customer.
The customer examination data is transmitted over a computer network (e.g., the Internet) from a customer diagnostic center to a diagnostic center server (step 630). The diagnostic center server may store all or a portion of the customer examination data. The diagnostic center server provides access to one or more practitioner devices to enable a practitioner device to access the customer examination data (step 640). This permits a practitioner operating a practitioner device to review the customer examination data from a location that is located remotely from the customer diagnostic center where the one or more tests are administered to the customer. In certain embodiments, a practitioner may access the customer examination data in real-time as tests are being administered to the customer. In certain embodiments, a practitioner may access the customer examination data after the tests are administered to the customer.
After or while the practitioner is reviewing the customer examination data, customer evaluation data is generated that pertains to the eye-care practitioner's review and evaluation of the customer examination data (step 650). The customer evaluation data received from the remote practitioner may include various reports, diagnoses, recommendations and other information indicating the results of the eye health and vision tests and procedures administered to the customer. In certain embodiments, the customer evaluation data may include an eye health report or may be used to generate an eye health report. The eye health report may include a summary of the customer's eye health, visual acuity, test results and procedures, diagnoses, optical prescriptions, pharmaceutical prescriptions, recommendations, treatment instructions, referrals to see other eye care professionals, and/or other data that is associated with the customer, practitioner or the customer's visit to the customer diagnostic center. The eye health report which is based, at least in part, on the customer evaluation data is then provided to the customer through the network (step 660). The eye health report may be provided to a customer in various ways. In certain embodiments, the eye health report may be presented to the customer through the diagnostic center 10. In certain embodiments, the customer may be permitted to access the eye health report using one or more computing devices associated with the customer. In certain embodiments, the customer may be permitted to download a copy of the eye health report from a website after logging in (e.g., with a username and password) to an account on the website. In certain embodiments, the eye health report may be transmitted to the customer via electronic mail.
Exemplary Methods for Providing Vision and Eye Health Examinations
FIG. 7 is a flow chart illustrating an exemplary method 700 for administering a synchronous vision examination in accordance with certain embodiments of the present invention. Initially, a connection is established between a customer diagnostic center 10 and a remote practitioner device 30 (step 710). In certain embodiments, a request may be transmitted to a server from the customer diagnostic center for establishing the connection and the request may be accepted by the remote practitioner device 30. A remote practitioner associated with the remote practitioner device 30 may be selected by the server or an individual at the customer diagnostic center 10 and the remote practitioner may choose whether or not to accept the request. In certain embodiments, the connection may be established through the server (e.g., customer diagnostic center server 20, remote practitioner management server 24 or other server) or made directly between the customer diagnostic center 10 and the remote practitioner device 30. In certain embodiments, the connection may provide a live audio/video stream to both the remote practitioner device 30 and the customer diagnostic center 10 in order to facilitate communication between a remote practitioner who is operating the remote practitioner device 30 and a customer and/or on-site personnel located at the customer diagnostic center 10. Any data transmitted via the connection may be encrypted for security purposes.
Next, a preliminary refractive error is determined for the customer located at the customer diagnostic center 10 (step 720). The preliminary refractive error may be determined by analyzing prior prescriptions, analyzing data associated with prior vision examinations, retrieving customer data that is stored in a database or a tangible record, utilizing a lensometer 144, or by other means.
After a preliminary refractive error is determined for the customer, an interactive refraction test may be administered to the customer in a manner that permits the remote practitioner to monitor and control the vision examination (step 730). In certain embodiments, the remote practitioner may be presented with an interface on the remote practitioner device 30 that permits the practitioner to control the equipment (e.g., turn the equipment on/off, move the equipment, take measurements, etc.). For example, by selecting interface elements (e.g., buttons, links or on-screen controls) on the interfaces, the practitioner may cause the remote practitioner device 30 to transmit commands to the equipment controller 130 located at the customer diagnostic center 10, thus permitting the practitioner to operate and manipulate the equipment. The remote practitioner may be permitted to control any equipment that is relevant to providing a vision examination including, but not limited to, an auto phoropter 141, lens houser 142, auto-refractor 143, lensometer 144 and eye chart 145 (and any projector associated with an eye chart). In certain embodiments, the remote practitioner may not be able to directly control the equipment. Rather, personnel at the diagnostic center 10 may control the equipment and the remote practitioner may provide instructions to the personnel via the established connection.
After or while the vision examination is administered, examination data associated with the vision examination (including examination data that indicates an updated refractive error for the customer) may be transmitted to the remote practitioner device 30 for review by the remote practitioner (step 740). In response, the customer may receive evaluation data and/or an eye health report from the remote practitioner (step 750). In certain embodiments, the evaluation data and/or an eye health report may be transmitted to the customer diagnostic center 10 from the remote practitioner device 30 while the customer is present at the customer diagnostic center 10. In certain embodiments, the evaluation data and/or an eye health report may be transmitted to the customer after the customer leaves the customer diagnostic center 10 (e.g., via e-mail, traditional mail service, or through a website).
FIG. 8 is a flow chart illustrating an exemplary method 800 for administering an asynchronous vision examination in accordance with certain embodiments of the present invention. A preliminary refractive error may initially be determined for a customer located at a customer diagnostic center 10 (step 810). The preliminary refractive error may be determined in the same ways discussed above. In certain embodiments, this step may be performed by technicians, operators, or other personnel located at the customer diagnostic center 10. In certain embodiments, this step may be performed by the customer (e.g., by permitting the customer to specify preliminary refractive error results from prior examinations). Next, a refraction test may be administered to the customer at the customer diagnostic center 10 (step 820) and an updated refractive error may be determined for the customer (step 830). Once again, these steps may be performed by technicians, operators, or other personnel located at the customer diagnostic center 10. In certain embodiments, the step of determining an updated refractive error may be performed at a subsequent time by a remote practitioner after reviewing the examination data associated with the vision examination.
After the refraction test is administered to the customer (and possibly after an updated refractive error has been determined), examination data associated with the vision examination is transmitted to a server for storage (step 840). The server may represent a customer diagnostic center server 20, remote practitioner management server 24 or other server. In certain embodiments, the vision examination system may be provided, at least in part, by a cloud-based service and the server may be associated with the cloud-based service. In certain embodiments, the stored examination data may be associated with a particular remote practitioner (e.g., which may be selected by a round robin process or who may be a practitioner who has serviced the customer in the past). One or more remote practitioners may be provided with access to the stored examination data located on the server (step 850). In certain embodiments, the remote practitioners may receive and accept a request for providing the asynchronous vision examination for the customer. The remote practitioners may be selected by an individual at the customer diagnostic center or by the server. In certain embodiments, the remote practitioner may enter login credentials (e.g., username and password) to access the stored examination data associated with the customer. After reviewing the examination data, the remote practitioner may provide evaluation data and/or eye health report to the customer (step 860). Once again, the evaluation data and/or an eye health report may be transmitted to the customer after the customer leaves the customer diagnostic center 10.
FIG. 9 is a flow chart illustrating an exemplary method 900 for administering a synchronous eye health examination in accordance with certain embodiments of the present invention. A connection may be established between a customer diagnostic center 10 and a remote practitioner device 30 prior to administering an eye health examination (step 910). In certain embodiments, a request may be transmitted to a server from the customer diagnostic center for establishing the connection and the request may be accepted by the remote practitioner device 30. A remote practitioner associated with the remote practitioner device 30 may be selected by the server or an individual at the customer diagnostic center 10 and the remote practitioner may choose whether or not to accept the request. In certain embodiments, the connection may be established through a server (e.g., customer diagnostic center server 20, remote practitioner management server 24 or other server) or established directly between the customer diagnostic center 10 and the remote practitioner device 30. Once again, the connection may provide a live audio/video stream to both the remote practitioner device 30 and the customer diagnostic center 10 in order to facilitate communication between a remote practitioner who is operating the remote practitioner device 30 and a customer and/or on-site personnel located at the customer diagnostic center 10. Any data transmitted via the connection may be encrypted for security purposes.
A remote practitioner may be permitted to control one or more ophthalmic devices located at the customer diagnostic center 10 for conducting the eye health examination (step 920). As explained above, the remote practitioner may be presented with an interface on the remote practitioner device 30 that permits the practitioner to control and manipulate the equipment by selecting interface elements or in other ways. The remote practitioner may be permitted to control any equipment that is relevant to providing an eye health examination including, but not limited to, a digital imager 151, bio-microscope 152, retinal camera 153, tonometer 154 and visual field instruments 155. The remote practitioner may then administer the eye health examination to the customer located at the customer diagnostic center 10 as the remote practitioner monitors the eye health examination in real-time (step 930).
After or while the eye health examination is administered to the customer, examination data associated with the eye health examination may be transmitted to the remote practitioner device 30 (step 940). In certain embodiments, the examination data may initially be transmitted to a server (e.g., customer diagnostic center server 20, remote practitioner management server 24 or other server) which may then provide the examination data to the practitioner device 30 or make the examination data available to the practitioner device 30. After the remote practitioner has reviewed the examination data, the customer may then receive evaluation data and/or eye health report from the remote practitioner (step 950). As mentioned above, the evaluation data and/or eye health report may be provided to the customer while the customer is at the customer diagnostic center 10 or afterwards by other means.
FIG. 10 is a flow chart illustrating an exemplary method 1000 for administering an asynchronous eye health examination in accordance with certain embodiments of the present invention. Initially, ophthalmic equipment is utilized to generate examination data associated with an eye health examination for a customer at a customer diagnostic center (step 1010). The examination data may include data generated by ophthalmic equipment or any other data associated with the eye health examination. This step may be performed by technicians, operators, or other personnel located at the customer diagnostic center 10. After or while the examination data is generated, the examination data may be transmitted to a server (step 1020) and stored on the server (step 1030). As mentioned above, the server may represent a customer diagnostic center server 20, remote practitioner management server 24, server associated with a cloud-based service or other server. In certain embodiments, the stored examination data may be associated with one or more remote practitioners. For example, a remote practitioner may be randomly selected to review the examination data (e.g., by selecting the practitioner using a round robin process or in other ways) or may be selected to review the examination data because the practitioner previously serviced the customer in the past (e.g., previously administered a vision or eye health examination to the customer).
One or more remote practitioners may be provided with access to the stored examination data located on the server (step 1040). In certain embodiments, the remote practitioners may receive and accept a request for providing the examination for the customer. The remote practitioners may be selected by an individual at the customer diagnostic center or by the server. In certain embodiments, the remote practitioner may enter login credentials (e.g., username and password) to access the stored examination data associated with the customer. After reviewing the examination data, the remote practitioner may provide evaluation data and/or eye health report to the customer (step 1050). As mentioned above, the evaluation data and/or an eye health report may be provided to the customer while the customer is at the customer diagnostic center 10 or afterwards by other means.
It should be recognized that the above methods are merely meant demonstrate how vision and eye health examinations can be administered to customers and are not meant to be limiting. Numerous variations can be made to the methods without departing from the scope of the present invention.
Extended Services and Functionality
In certain embodiments, customers may be able to view, compare, order and/or purchase various vision and/or eye care related products and services through the customer diagnostic centers and/or the eye testing and evaluation system. For example, the customer diagnostic centers and/or the eye testing and evaluation system may store and/or access various information associated with products (e.g., eyeglasses, contact lenses, etc.) that are offered by one or more third parties. As a result, customers may be able access, view and/or browse through these products at the customer diagnostic centers (e.g., through a display screen included with the customer interface). Customers may also, or instead, be able to access the products from other devices (e.g., a computing device associated with the customer), such as through a web-based service or client application installed on the customer's device.
In certain embodiments, the customer diagnostic centers and/or the eye testing and evaluation system may display a virtual representation or simulation of the customer wearing or using a particular product in order to illustrate how certain products would look on the customer. For example, the customer may be able to view a virtual representation of his or her face and/or head, and select one or more eyeglasses to be shown with the virtual representation. In certain of these embodiments, the virtual representation of the customer may be based on data obtained through one or more tests associated with the vision examinations and/or eye health examinations (e.g., via digital imaging devices, video cameras, etc.).
According to certain embodiments, the customer diagnostic centers and/or the eye testing and evaluation system may be configured to recommend one or more vision and/or eye care related products and services to the customers. For example, the eye testing and evaluation system may select one or more products to recommend to a customer based on various data associated with the customer, such as customer data (e.g., income, sex, age, prior products purchased, etc.) and/or customer examination and evaluation data (e.g., refractive error, optical specifications, astigmatism, etc.). Similarly, the eye testing and evaluation system may determine product recommendations for a customer based on data associated with various other customers, such as by identifying products purchased by customers with similar characteristics, backgrounds, disorders, etc. In certain other embodiments, the product recommendations may be based on a “preferred” status associated with one or more third party vendors (e.g., vendors who pay a fee to emphasize their products and services).
In certain embodiments, after a customer has browsed through and selected one or more products and services, the customer may be able to order and/or purchase the selected products and services through the customer diagnostic center. In certain of these embodiments, the customer diagnostic center and/or eye testing and evaluation system may forward various data to the third party associated with the purchased products and services, such as order data, customer data, and/or customer evaluation data (e.g., optical specifications).
In certain embodiments, various advertisements and/or promotional materials (e.g., coupons, offers, discounts, etc.) may be presented or provided to customers through the customer diagnostic centers. In certain of these embodiments, for example, advertisements and promotions may be displayed to customers (e.g., through one or more displays included with the customer interface) before, during, and/or after the customer receives a vision examination and/or eye health examination through the customer diagnostic center. In certain embodiments, the advertising and promotional materials may include materials that are associated with various vision and eye care related products and services, and/or may include materials for a wide range of other consumer products and services. In certain embodiments, such as where the customer diagnostic center includes a printing device, the customers may be able to print out a hard copy of one or more promotions, such as coupons. Alternatively, or in addition, customers may be able to select an option to forward the advertisement or promotion to themselves (e.g., via e-mail or text).
Importantly, the incorporation of advertising and promotional materials and other similar services (e.g., allowing vendors to pay for preferred status) provides certain benefits to customers. One such benefit is that, given the revenue generated through such mechanisms, customers may be able to receive vision examinations and/or eye health examination at a significantly reduced cost, or may even be able to receive certain services at no charge, thereby encouraging customers to receive such examinations on a regular basis.
In certain embodiments, the eye testing and evaluation system may be configured to send various notifications and messages to customers (e.g., through email, text, and/or via one or more computing devices associated with the customers). For example, in certain embodiments, the eye testing and evaluation system may send a message to a customer to remind the customer that it is time to receive a vision examination and/or eye health examination, or to remind the customer about an upcoming appointment with an external practitioner (e.g., in connection with a previous referral for in-person evaluation). Similarly, the eye testing and evaluation system may send messages to a customer requesting confirmation that the customer has made an appointment with and/or visited an external practitioner (e.g., in the case where a referral for urgent follow-up testing was provided to the customer).
It is understood that the various systems, devices, and methods described in connection with the foregoing figures are exemplary, and any other suitable systems, devices or methods may be used. The foregoing is merely illustrative of the principles of this invention and various modifications can be made by those skilled in the art without departing from the scope and spirit of the invention. As an example, although certain embodiments of the eye testing and evaluation system have been described in connection with a particular number of customer diagnostic centers and/or remote practitioner devices having certain formats or types, the platform may include any number, format and type of customer diagnostic centers and/or remote practitioner devices. As another example, while the customer diagnostic centers have been described as having certain exemplary ophthalmic equipment and instruments, the customer diagnostic centers may utilize virtually any suitable type of such devices and instruments. One skilled in the art will appreciate that the present invention can be practiced in other than the described embodiments, which are presented for purposes of illustration and not limitation.
