Title: Method and device for monitoring ophthalmic lens manufacturing conditions

Description:
TECHNICAL FIELD 
     The disclosure generally relates to a method and a communication system device used to monitor manufacturing conditions. More particularly, it relates to the method of monitoring controlled manufacturing conditions of an ophthalmic lens and generating an unique identifier. 
     BACKGROUND 
     Traditionally, ophthalmic devices, such as a hydrogel lens, an intraocular lens or a punctal plug, include corrective, cosmetic or therapeutic qualities. A contact lens, for example, may provide vision correcting functionality, cosmetic enhancement, and/or therapeutic effects. Each function is provided by a physical characteristic of the contact lens. For example, a refractive quality may provide a vision corrective function, a pigment may provide a cosmetic enhancement, and an active agent may provide a therapeutic functionality. 
     Ophthalmic lens manufacturing processes include, for example, sandwiching a monomer between back curve (upper) and front curve (lower) mold sections carried in a mold array. The monomer is polymerized, thus forming a lens, which is then removed from the mold sections and further treated in a hydration bath and packaged for consumer use. A more recently developed manufacturing process for manufacturing high quality customized ophthalmic lenses is disclosed in U.S. Pat. No. 7,905,594 to Widman, et al. which is assigned to the assignee of the present disclosure. 
     In order to reach greater design ranges and higher optical quality, currently, these and other manufacturing techniques are carried out by partially automated and semi-automated apparatus and processes with strict process controls and tight tolerances necessary for the production of high quality ophthalmic lenses. Evolving techniques employ different process controls seeking to improve or add a particular manufacturing step. Examples of newly developed methodologies include new ways of demolding the lens from the mold part, the application of binder layers to the mold parts, polymerization techniques, lens hydration techniques, metrology techniques, lens material development, and the such. 
     With new methods and lens components being developed, the complexity of troubleshooting the desired automated process controls is sometimes greater. In addition, because some faults may not be detected prior to the detection of a defective ophthalmic lens during quality control, fault identification and correction can often be subject to a time delay wasting production time and materials. As a result, while the aforementioned production processes have some efficacy in the production of soft contact lenses, they suffer a number of disadvantages which can hinder the development of a high speed automated production line capable of producing high quality ophthalmic lenses. Furthermore, with the increasing risk of these high quality ophthalmic lenses being counterfeited, it is desirous for the ophthalmic lens to include a communication system useful to provide information about the ophthalmic lens&#39; production. 
     Therefore, there is a need for a communication system that can be incorporated in an ophthalmic lens and/or mold part during early stages of manufacturing and which can be useful to generate a unique identifier with correlated production information. 
     SUMMARY 
     Accordingly, the foregoing needs are met, to a great extent, by one or more embodiments of the communication system. In accordance with some embodiments, the communication system includes a nano-antenna incorporated into or onto an ophthalmic device during manufacturing and is coded with an unique identifier. 
     According to aspects of the disclosure, a method of monitoring ophthalmic lens manufacturing controlled conditions is disclosed. The method can comprise: placing a communication system on a lens forming surface of a mold; energizing a communication system; storing a unique identifier in the communication system; measuring a controlled condition during manufacturing of the ophthalmic lens using at least one or more sensor(s) in the communication system; transmitting sensor data relating to the measured condition to a processor; and identifying a deficiency in the controlled condition using the sensor data and the unique identifier. 
     In some embodiments of the disclosure, an ophthalmic lens can include: a hydrogel portion supporting a communication system; the communication system comprising: a processor in logical communication with one or more sensor(s) configured to measuring a controlled condition during manufacturing of the ophthalmic lens; a nano-antenna capable of receiving energy to energize the processor and the one or more sensor(s) and transmit sensor data relating to the measured controlled condition; and wherein the processor is capable of storing a unique identifier. 
     Certain implementations of the ophthalmic device and communication system including the antenna configuration have been outlined so that the detailed description below may be better understood. There are, of course, additional implementations that will be described below and which will form the subject matter of the claims. 
     In this respect, before explaining at least one implementation in detail, it is to be understood that the hydrogel lens including the communication system is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. Also, it is to be understood that the phraseology and terminology employed herein, as well as in the Abstract, are for the purpose of description and should not be regarded as limiting. 
     As such, those skilled in the art will appreciate that the conception upon which this disclosure is based may readily be utilized as a basis for the designing of other structures, methods, and systems for carrying out the several purposes of the ophthalmic lens including the control, subsequent to the manufacturing of the ophthalmic lens, of dynamic components that may be included in some embodiments. It is understood, therefore, that the claims include such equivalent constructions insofar as they do not depart from the spirit and scope of the present application.

     Referring now to  FIG. 1 , a diagram of an exemplary Mold for an Ophthalmic Lens with a Communication System  109  is illustrated. As used herein, the term Mold can include a mold assembly  100  having a cavity  105  into which a Lens forming mixture  110  can be dispensed such that upon reaction or cure of the Lens Forming Mixture, an Ophthalmic Lens of a desired shape is produced. In some embodiments, the Molds and mold assemblies  100  may be made up of more than one “mold parts” or “mold pieces”  101 - 102 . For example, the mold parts  101 - 102  can be brought together such that a cavity  105  is formed between the mold parts  101 - 102  in which a lens can be formed. This combination of mold parts  101 - 102  is preferably temporary. Upon formation of the Ophthalmic Lens, the mold parts  101 - 102  can again be separated and the Ophthalmic Lens can be Released from a Mold. 
     At least one mold part  101 - 102  has at least a portion of its Lens Forming Surface  103 - 104  in contact with the Lens Forming Mixture such that upon reaction or cure of the Lens Forming Mixture  110  that surface  103 - 104  provides a desired shape and form to the portion of the Ophthalmic Lens with which it is in contact. The same may be true of at least one other mold part  101 - 102 . 
     Thus, for example, in one preferred embodiment a mold assembly  100  can be formed from two parts  101 - 102 , a female concave piece (front piece)  102  and a male convex piece (back piece)  101  with a cavity formed between them.

     In some embodiments, the front mold piece  102  can also have an annular flange integral with and surrounding circular circumferential edge  108  and extends from it in a plane normal to the axis and extending from the flange (not shown). 
     A Lens Forming Surface can include a surface  103 - 104  with an optical quality surface finish, which indicates that it is sufficiently smooth and formed so that an Ophthalmic Lens surface fashioned by the polymerization of a Lens Forming Mixture in contact with the molding surface is optically acceptable. Further, in some embodiments, the Lens Forming Surface  103 - 104  can have a geometry that may be necessary to impart to the lens surface the desired optical characteristics, including without limitation, spherical, aspherical and cylinder power, wave front aberration correction, corneal topography correction and the like as well as any combinations thereof. 
     Mold part  101 - 102  material can include a polyolefin of one or more of: polypropylene, polystyrene, polyethylene, polymethyl methacrylate, and modified polyolefins. A preferred alicyclic co-polymer contains two different alicyclic polymers and is sold by Zeon Chemicals L.P. under the trade name ZEONOR. There are several different grades of ZEONOR. Various grades may have glass transition temperatures ranging from 105° C. to 160° C. A specifically preferred material is ZEONOR 1060R. Other Mold materials that may be combined with one or more additives to form an Ophthalmic Lens Mold include, for example, Zieglar-Natta polypropylene resins (sometimes referred to as znPP). On exemplary Zieglar-Natta polypropylene resin is available under the name PP 9544 MED. PP 9544 MED is a clarified random copolymer for clean molding as per FDA regulation 21 CFR (c)3.2 made available by ExxonMobile Chemical Company. PP 9544 MED is a random copolymer (znPP) with ethylene group (hereinafter 9544 MED). Other exemplary Zieglar-Natta polypropylene resins include: Atofina Polypropylene 3761 and Atofina Polypropylene 3620WZ. Still further, in some embodiments, the Molds of the disclosure may contain polymers such as polypropylene, polyethylene, polystyrene, polymethyl methacrylate, modified polyolefins containing an alicyclic moiety in the main chain and cyclic polyolefins. This blend can be used on either or more Mold parts, for example, where it is preferred that this blend is used on the back curve and the front curve consists of the alicyclic co-polymers. 
     In some preferred methods of making Molds  100 , injection molding can be utilized according to known techniques, however, embodiments can also include Molds fashioned by other techniques including, for example: lathing, diamond turning, or laser cutting. Typically, lenses are formed on at least one surface of both Mold parts  101 - 102 . However, in some embodiments, one surface of an Ophthalmic Lens may be formed from a Mold part  101 - 102  and another surface of a lens can be free-formed as described by other methods.

Various embodiments may include the Media Insert  320  locating the pattern of circuitry, components and Energy Sources around a periphery of an Optic Zone through which a wearer of an Ophthalmic Lens would see, while other embodiments may include a pattern of circuitry, components and Energy Sources which are small enough to not adversely affect the sight of the Ophthalmic Lens wearer and therefore the Media Insert  320  may locate them within, or exterior to, an Optical Zone. 
     Referring now to  FIG. 4 , a schematic design of the exemplary Communication System  109  of  FIG. 1  comprising a nano-antenna  401  according to some aspects of the disclosure is illustrated. In some preferred embodiments, the nano-antenna  401  can be a fractal antenna configured to operate at different frequencies. The nano-antenna  401  may be made up of a conductive material, such as, a metallic material. Suitable metallic materials can include, for example, gold, graphene, silver and copper. Conductive fibers such as conductive carbon fibers can also be suitable. The nano-antenna may function as an energy receptor configured to provide a self-powered nano-Communication System  109 , for example, when it is exposed to a heavy radial frequency field absorbing enough energy to power other electronic components. A fractal shape may include a repeating pattern or any other mathematical set that has a dimension that usually exceeds its topological dimension. Another type of nano-antenna  401  can include a nano-optical Yagi-Uda antenna or the such. 
     In some embodiments, the nano-antenna  401  can be in communication nano-transceiver  402  which may be configured to perform functions including baseband processing, frequency conversion, filtering and power amplification, of the received signals transmitted into and/or out of the nano-antenna  401 . A nano-actuator  403  may also be included in the Communication System  109  to allow one or more nano-sensor(s)  406  to interact with the surrounding environment. Nano-sensors can include, for example, one or more of: physical nano-sensors capable of measuring mass, pressure, force, and/or displacement; chemical nano-sensors configured to measure chemical compositions and/or concentrations; and, biological nan-sensors configured to measure antibody/antigen interaction, DNA interaction, and/or enzymatic interactions. Nano-actuator  403  may include one or more of: physical, chemical or biological actuators. A nano-processing device  404  comprising nano-memory  405  in communication with the sensor  406  can function, for example, to control the recording measured conditions by the sensor  406 , execute operational sequences, generate and/or transmit data related to the Ophthalmic Lens Pedigree Profile. 
     In general, according to the embodiments previously described, a Media Insert  320  and/or self-powered nano-Communication System  109  can be embodied within or on an ophthalmic lens via automation which can places/deposit the components on a desired location relative to a mold part used to fashion the Ophthalmic Lens. 
     Apparatus 
     Referring now to  FIG. 5 , automated apparatus  510  is illustrated with one or transfer interfaces  511 . As illustrated, multiple mold parts can each be associated with a mold part receptacle  514  contained within a pallet  513  and presented to the transfer interface(s)  511 . The transfer interface(s)  511  can place or deposit a standalone Communication System (shown in  FIG. 4 ) or a Media Insert (shown in  FIG. 3 ) containing the Communication System configured to generate an Ophthalmic Lens Pedigree Profile. Embodiments can include, for example, a single interface individually placing a single Communication System on a programmed manner onto a mold part receptacle  514 , or multiple interfaces (not shown) simultaneously placing multiple Communication Systems within multiple mold parts, and in some embodiments, within each mold part. 
     Another aspect of some embodiments includes apparatus to support the Communication System while the hydrogel body of the Ophthalmic Lens is molded around the Communication System. For example, in some embodiments the communication system may affix to holding points in a Mold (not illustrated). In some embodiments, the holding points may preferably be affixed with polymerized material of the same type that will be formed into the lens body. 
     Referring now to  FIG. 6 , a schematic diagram of a controller  600  that may be used with some embodiments of the present disclosure is illustrated. The controller  600  includes a processor  610 , which may include one or more processor components coupled to a communication device  620 . In some embodiments, a controller  600  can be used to transmit energy to the energy source placed in the Ophthalmic Lens. 
     The controller  600  can include one or more processors  610 , coupled to a communication device  620  configured to communicate logical signals via a communication channel. The communication device  620  may be used to electronically control one or more of: the placement of a microcontroller and a flexible media into the Ophthalmic Lens and the transfer of command to operate a component or the microcontroller. 
     The communication device  620  may also be used to communicate, for example, with one or more controller apparatus or manufacturing equipment components. 
     The processor  610  is also in communication with a storage device  630 . The storage device  630  may comprise any appropriate information storage device, including combinations of magnetic storage devices (e.g., magnetic tape and hard disk drives), optical storage devices, and/or semiconductor memory devices such as Random Access Memory (RAM) devices and Read Only Memory (ROM) devices. 
     The storage device  630  can store a program  640  for controlling the processor  610 . The processor  610  performs instructions of the program  640 , and thereby operates in accordance with the present disclosure. For example, the processor  610  may transmit data including, for example, unique identifier, sensor data, design information and other data that can be included in the Pedigree Profile. The storage device  630  can also store ophthalmic related data in one or more databases  650 - 660 . The database may include customized user data, Ophthalmic Lens Pedigree profiles, metrology data, and specific control sequences for controlling energy to and from the Communication System. 
     In some embodiments, an Ophthalmic Lens with an activation component operative to provide energy from an energy source incorporated into a Media Insert. 
     Referring now to  FIG. 8 , method steps that can be used to generate an Ophthalmic Lens Pedigree Profile are shown. At  801 , a Communication System is energized. Energization may take place, for example, using an internal Energy Source contained in a Media Insert and/or through a nano-antenna configured to be an energy receptor and energize other components of the Communication System when it is placed in a high frequency field. 
     At  802 , data relating to a unique identifier can be transmitted to a database included in one or both of a database stored in memory contained within the Communication System and a database of an external processor in communication with the Communication System. The unique identifier may be a serial number that can be recorded during the manufacturing of the die and/or a numerical value assigned to a Pedigree Profile generated throughout the manufacturing of the Ophthalmic Lens  803 . In some preferred embodiments, the unique identifier may be stored in a database and correlated to additional information. Additional information can include, for example, lens manufacturer information, customer/user data, lens design, Pedigree Profile and the like. Further, in some embodiments, the unique identifier can be encrypted and recorded in a coded signal that can be used to access said Pedigree Profile. The coded signal can be recorded in the Communication System and accessed by an external system, for example, on demand to protect the user by ensuring the Ophthalmic Lens is not a counterfeited product  804 . In addition to ensuring authenticity, additional information relating to the Ophthalmic Lens, patient, and/or manufacturer that may be stored in a database and associated with the Ophthalmic Lens may be accessed. 
     Referring now to  FIG. 7 , exemplary method steps that may be used to monitor and/or troubleshoot manufacturing controlled conditions are shown. At  701  a Communication System is placed on a Lens Forming Surface. At  702  the Communication System can be energized. At  703  a Lens Forming Mixture is put in contact with the Lens Forming Surface by immersion of the Lens Forming Mixture onto a container or depositing the Lens Forming Mixture to the Mold including the Lens Forming Surface. At  704 , the Ophthalmic Lens can be formed according to an Ophthalmic Lens design using a suitable manufacturing method. Controlled conditions or processed during the depositing of the Lens Forming Mixture  703  and/or the forming of the Ophthalmic Lens  704  can be monitored using one or more sensors in communication with, and/or comprised by, the Communication System. At  705 , data relating to a controlled condition can be transmitted to a processor. At  706 , the processor can compare predetermined thresholds values to the transmitted data to conform to the Ophthalmic Lens design. At  707  when the measured data is determined to be outside the predetermined threshold, the processor may modify a subsequent process controlled condition to counteract the previous deficiency if appropriate. At  708 , the processor may categorize the Ophthalmic Lens as a non-conforming one that should be discarded. 
     At  710 , the Ophthalmic Lens may undergo quality control procedures in which controlled conditions may also be monitored. When a non-conformity/fault is identified, either during the manufacturing  708  or the quality control process  710  the recorded data may be used to identify the accounted process fault for the non-conformity in the manufacturing line  709 . In some preferred embodiments, the processor may additionally send an alert to the manufacturing line operator/controller and stop the line until further input is provided by the operator/controller. As previously mentioned, all of the transmitted data may be recorded in a database and used to generate the Pedigree Profile corresponding to the unique identifier stored in the Communication System  711 . Once completed, the ophthalmic lens is provided to a user at  712 .
