Purpose 
The purpose of this study is to explore the wear experience of current Comfilcon A (Biofinity® toric) 
contact lens wearers after they have been fit into Verofilcon A (PRECISION1®) Contact Lenses for 
Astigmatism.   
 
Study Overview 
This open-label study is of current Biofinity® toric (Cooper Vision, San Ramon, CA, USA) contact lens 
wearers who are satisfied with their lenses. Subjects will be refit into PRECISION1® for Astigmatism 
contact lenses and will wear lenses for approximately 2 weeks.  Subjects will return for vision and lens fit 
assessments and will complete surveys about their wear experience. 
 
Background 
Soft daily wear contact lenses are used by an estimated 40.9 million adults in the United States.1  Contact 
lenses which are worn for daily wear are considered minimal risk by the FDA, and risks to wearers are 
minimized by proper lens care and hygiene. Daily disposable contact lenses do not require daily cleaning 
and overnight storage, which improves the required amount of time to care for contact lenses.  In 
addition, daily disposable contact lenses are associated with less lens deposits, which decreases 
associated comfort issues in lens wearers, including decreasing the risk of triggering Giant papillary 
conjunctivitis (GPC) and/or ocular allergic responses in patients.2  Additionally, daily disposable contact 
lens wearers are not likely to expose their lenses to water and tend to have better lens hygiene since these 
lenses do not require daily cleaning.  This is reflected in a study which found less superficial punctate 
staining and symptoms of dryness when comparing daily disposable contact lens wear with planned 
replacement lenses.3 The subjects in this study are current satisfied wearers of 1 month planned 
replacement lenses (Biofinity®) and will be fit into PRECISION1 for Astigmatism daily disposable contact 
lenses, which are less likely to be associated with the already minimal risks of daily contact lens wear.

Key Endpoints: 
• 
Visual Analog Scale survey of lens wear symptoms (comfort, dryness, vision) 
• 
Subjective assessment of P1 with CLDEQ-8  
• 
Assessment via questionnaire about quality of life, preference, and lens modality experience 
 
Study Time Points: 
Visit 1 will be conducted to consent the subject and determine eligibility.  Consenting will be conducted 
via phone call and REDCap and will occur before the subject arrives on site if possible.   The participant 
will verify their current prescription for Biofinity® lenses in which one or both eyes utilizes a toric lens for 
astigmatism.  The participant will answer questions about ocular health to further determine eligibility. 
Participants will also verify that they are happy with their current lenses. Upon reporting to the in-person 
portion of the visit, visual acuity and an evaluation of the subject’s ocular health will occur. Biofinity® 
lenses will be evaluated and optimized before dispensing a new pair of lenses for approximately 1 week 
of wear. 
Visit 2: Biofinity® contact lens follow up and Precision 1 fitting visit.  Patients will verify that they are still 
satisfied with their current Biofinity® toric contact lenses in order to proceed and vision, lens fit and ocular 
health will be assessed.  Subjects will then be fit with PRECISION1® Contact Lenses for Astigmatism with 
assessments of initial satisfaction, initial comfort, and initial vision.  Lenses will be dispensed and a contact 
lens follow-up visit will be scheduled. 
Visit 3: The contact lens follow up visit will occur approximately 2 weeks (±3 days) following the initial 
fitting.  Subjects will have visual acuity, an assessment of ocular health, and lens fit completed.  Subjects 
will then complete surveys about their lens wear experience. 
 
 
Surveys will include:  
CLDEQ-8  
VAS survey of comfort/dryness/vision

Recruitment 
Potential subjects may see posters placed on bulletin boards at The Ohio State University or local eye care 
offices, emails to students, faculty and staff at OSU, online or paper ads, or signs on the OSU buses.  A 
search of the electronic medical records of The Ohio State College of Optometry may be done to identify 
possible subjects who then may be contacted by email or phone with information about the study. Word 
of mouth referrals by study team members to OSU employees and friends may occur.  Emails to alumni 
of the OSU College of Optometry may be sent for local doctors to notify eligible potential subjects about 
the study. 
 
Inclusion criteria:  
• 
Subjects must be current Biofinity® toric lens wearer in one or both eyes.    
• 
Subjects must have 20/25 or better distance visual acuity with current lenses. 
• 
Good general health (defined by medication use that has not changed within the last 
month and the absence of medical conditions or treatments that are deemed 
confounding to the data as determined by the PI) 
• 
Ability to give informed consent  
• 
Willing to spend time for the study.  Subjects will be required to attend two study visits 
and wear contact lenses on days between study visits.   
• 
Either gender 
• 
Any racial or ethnic origin 
Exclusion criteria:  
• 
No current ocular inflammation or infection as assessed by the study investigator 
 
Consent and Confidentiality 
A team member trained in the consent process will provide the consent document for the potential 
subject to read and will review the procedures with reference to the consent form. The individual is then 
provided with time to read the consent form and offered the opportunity to ask questions. The participant 
is explicitly told that they may stop participation at any time. All subjects will have the capacity to give 
informed consent. If there is any doubt as to the subject’s ability to consent to the study, the subject will 
be excluded from the study. If the subject agrees to take part in the screening or measurement, he or she 
will sign and date the most recent IRB-stamped consent as will the team member. The subject will be 
provided with a copy of the consent form. 
The investigator team is trained in privacy issues and will be reminded of the importance of patient privacy 
prior to study initiation. Potential study participants will contact us after seeing advertisements, emails or 
hearing about the study by word of mouth, giving them the choice of whether or not they wish to 
participate in a study for people with dry eyes.  Privacy is protected by limiting information related to 
study recruitment only, and no other personal or medical information that should be private to the 
patients. The PHI needed is only for the purposes of this study. It is highly unlikely, indeed extremely 
remote that the dry eye symptoms or signs are related to private or personal information that should or 
would be preferred to be kept confidential to the patients. Risk factors for dry eye rarely relate to matters

or conditions that would be personal to the patient such as personal relationships, behaviors or diseases 
that one prefers to keep private and confidential. 
 
Statistical Analysis and Power Calculation 
This small sample size of 30 was chosen for convenience, as this study is not intending to prove superiority, 
but to study the acceptability of the study lens in previous successful Biofinity® wearers.  
 
Data Management and Security 
During the active stages of the study (recruitment to last measurement visit), all paperwork (consents, 
questionnaires and data forms) for each subject will reside in a subject folder for easy access throughout 
the study. The folders will reside in the limited-access research area, in a locked file drawer or cupboard. 
At the completion of the study or disenrollment of a subject the paperwork in the subject’s folders will be 
reorganized into a regulatory binder (consents, W-9s) and a data binder (questionnaire and data forms) 
and will reside in an office in the limited-access research area. When the data analysis is completed and 
the study is considered complete, the binders will be stored in the secure Department or Office Clinical 
Research Area. Paperwork (questionnaire and data forms) for individuals who participate in the baseline 
visit but are not eligible to continue the study will be stored in the study regulatory binder in an office in 
the limited-access research area. An electronic file of potential subjects and a file of enrolled subjects with 
their contact information, as well as electronic files of collected data with the subject number, will reside 
on a limited-access shared drive with firewall and password protection and is restricted to individuals in 
the research team. Any electronic data files that contain PHI will be destroyed at the conclusion of the 
study. 
 
Risks to Subjects and Mitigation 
Although rare, a subject could experience eye pain, changes in vision, continued redness or irritation of 
the eye when inserting or learning to insert a contact lens. More likely transient blurring of vision (less 
than one minute) or mild, transient (less than a minute) stinging may occur. 
 
Adverse Events 
All adverse events will be documented and reported under the guidelines of The Ohio State University 
Event Reporting guidelines, with any serious, unanticipated and related events being reported to the IRB, 
by the PI, within 10 days. Adverse Events information will be summarized in the annual report to the IRB 
at the end of the study.  Adverse events will be assessed and determined by Dr. Jennifer Fogt.  
 
Subject Dismissal  
Subjects who, after study team member coaching, are not able to provide analyzable data may be 
dismissed from the study. Data may not be analyzable if a participant is unable able to utilize the

examination room equipment, for example. These issues are usually revealed at the screening assessment 
visit. Subjects who cannot provide analyzable data will be dismissed for the study. Subjects who do not 
keep scheduled visits within the required time frame will be dismissed from the study. Study team 
members will make reasonable efforts to accommodate subjects’ schedules.  
 
Protocol Violations, Discontinuation  
In the event that a member of the study team or a representative of sponsor becomes aware of a major 
protocol violation, the IRB shall be notified within 10 working days.
