1 Introduction 
A recent publication from 2021 comparing the data in the US market from three sources, indicates that 
the daily disposable modality continues to lead in terms of prescribing by soft lens replacement 
schedule (range of 43% to 51%)1. Toric soft contact lenses, (TSCL), work best for people with 
astigmatism and other refractive errors (e.g., nearsightedness, farsightedness). The use of toric soft 
contact lenses (TSCL) has increased significantly in recent years. Soft toric contact lens wearers 
demand two things from their contact lenses, great comfort and excellent vision. Recently released 
data on prescription habits with soft toric lenses ranged from 13% to 59%. Contact lens manufacturers 
are continuously innovating in this area, with increased availability of soft toric contact lenses with 
novel designs in a range of replacement frequencies, from daily disposables to monthly replacement, 
and different materials, including silicone hydrogels. 
Therefore, CooperVision is interested in comparing the short-term clinical performance and subjective 
acceptance of Biomedics 1 Day Toric hydrogel contact lenses (LENS A) with MyDay Toric (LENS B) 
silicone hydrogel lenses. A non-dispensing fitting study is proposed to evaluate the short-term clinical 
performance of these two daily disposable lenses. 
2 Study Objective 
 
The aim of this non-dispensing fitting study is to evaluate the short term lens fit, vision performance 
and patient subjective experiences of the Biomedics 1 Day Toric when compared to the MyDay Toric 
lenses after 15 minutes of daily wear.  
The primary outcome variable is: 
• 
Subjective handling ratings on insertion (assessed by subjects) 
 
 
  
 
 
 
 
 
 
 
 
 
 
3 Study Hypothesis  
3.1 Study Hypothesis  
• 
Null hypothesis (Ho): There is no difference in clinical performance and subjective 
assessments between toric lens types. 
• 
Alternative hypothesis (H1): There is a difference in clinical performance and subjective 
assessments between toric lens types.

6.3 Clinical Trial Registration 
This study will be registered with clinical trials.gov in accordance with section 801 of the Food and 
Drug Administration (FDA) Act which mandates the registration of certain clinical trials of drugs and 
medical devices. 
6.4 Informed Consent 
Informed consent, (Appendix 1), shall be obtained in writing from the subject and the process shall be 
documented before any procedure specific to the clinical investigation is carried out. 
7 Potential Risks and Benefits to Human Subjects 
There may be direct benefits to the subjects in this study such as improved vision, comfort, 
convenience, and cosmetic advantage.   Participation in a study may contribute to scientific research 
information that may be used in the development of new contact lens products. In addition, subjects 
will receive an examination of the front part of their eyes and may have the opportunity to try a different 
type of soft contact lenses and/or different lens care products at no cost to them. The contact lens 
materials used in this study are commercially available intended for daily wear (NOT extended wear) 
similar to the average wearing time of 10-16 hours for daily wear lenses.  
This study is considered to be a non-significant risk study based on United State Food and Drug 
administration (FDA) and International Standards Organization (ISO) guidelines because the study 
devices used as intended in this study (daily wear) don’t represent a potential for serious risk to the 
health, safety or welfare of the subject, and (2) it is not an implant, (3) it is not used to support or 
sustain human life, (4) it is not of substantial importance in diagnosing, curing, mitigating or treating 
disease or otherwise prevents impairment of human health, (5) does not present a potential for serious 
risk to the health, safety or welfare of the subject.   
Complications that may occur during the wearing of contact lenses include discomfort, dryness, aching 
or itching eyes, excessive tearing, discharge, hyperemia and variable or blurred vision.  More serious 
risks may include photophobia, iritis, corneal edema or eye infection. Although contact lens-related 
infections are very infrequent, the possibility does exist.  The incidence of infection due to day-wear 
soft lenses is 0.035%. Almost always an infection will occur only in one eye.  This risk is assumed by 
35-million Americans who currently wear contact lenses. Routine clinical procedures including auto-
refraction, auto-keratometry, visual acuity, anterior ocular health assessment, and contact lens fitting 
will be used. In addition, high magnification imaging of the lens fit may be made using 35 mm or digital 
cameras, in vivo confocal microscopy, and/or specular microscopy. Patients will be monitored in the 
clinic during the study to reduce if not eliminate the occurrence of adverse or potential adverse events. 
Patients will be given instructions from the study investigator regarding early symptoms and signs of 
adverse events and their contact information.

8.2 Study Materials 
8.2.1 Contact lens 
CooperVision will provide the site with an inventory of both study lenses (LENS A) and (LENS B) to 
allow participants to be fit with the lens powers available for this study.  
All subjects will be trial fitted and, if suitable, dispensed the first pair of the assigned lens brand 
assigned per a determined table (Appendix 3). The lenses used in this study are all FDA approved 
and marketed products. Details of the study contact lenses are shown in Table1.

masked because of the need to follow the specific lens fitting guide during the lens prescription 
optimization visit.     
8.2.7 Ordering and Accountability of Study Materials 
The study sponsor will supply the investigators with the study lenses to use during the study.  
8.3 Visit Schedule and Procedures 
This will be an interventional, subject masked, bilateral, non-dispensing fitting study.  Participants will 
be examined at two different points over the course of one day, lens dispensing,  and15 minutes post 
lens settling.  Participants will wear two different pairs of lenses with LENS A fitted first to all 
participants, followed by LENS B. Anterior ocular health examination will be performed at baseline 
without the use of fluorescein*.  
* Fluorescein will not be used before lens dispensing to prevent potential eye discomfort that could influence subjective 
comfort ratings after lens fitting and settling. However, fluorescein will be instilled at the last visit upon lens removal. 
The following outline identifies the four study visits and the general procedures, (Appendix 5), to be 
conducted at each visit for each day of the study and recorded in the case report forms (Appendix 6):

9 Adverse Event Reporting 
9.1 Adverse Response Definitions 
Adverse Event (AE): An AE refers to any untoward medical occurrence (sign, symptom or disease) 
in a trial subject that does not necessarily have a causal relationship with the study device.  AEs may 
be classified as ‘unanticipated adverse device effects,’ ‘serious AEs,’ ‘significant AEs,’ or ‘non-
significant AEs,’ as defined below.   

Confidential 
EX-MKTG-146 Clinical Evaluation of Biomedics 1 day Toric and MyDay toric 
17 
Adverse Event Form will be completed for each eye. Whenever possible, the adverse event will be 
photo-documented. 
Expenses incurred for medical treatment as part of study participation will be paid by the sponsor (bills 
and prescription receipts kept). The subject must be followed until resolution and a written report 
completed indicating the subsequent treatment and resolution of the condition. 
9.3 Reporting Adverse Events 
All potential Serious and Unanticipated Adverse Device Effects that are related or possibly related 
to subject participation in the investigation will be reported to the Principal Investigator and the sponsor 
within 24 hours of the investigator becoming aware of the event. The Principal Investigator will report 
the event to the EC/IRB as soon as possible (by fax, mail/delivery, phone, or email), but within 10 
business days of becoming aware of the problem.  All fatal or life threatening events will be reported 
immediately to the IRB. 
 
Significant and Non-Significant Adverse Events will be reported to the sponsor as soon as 
possible, but no later than 5 working days after the occurrence. 
 
 
  
 
 
  
 
 
  
 
 
  
 
 
 
 
9.4  Discontinuation from the Study  
All discontinuations will be fully documented on the appropriate CRF Exit and Adverse Event forms as 
needed.  Participants will be followed until resolution (in most instances) and are free of the ophthalmic 
insert related complications or other ocular pathology. When possible study lenses involved in an 
Adverse Event will be returned to the sponsor in a new tightly sealed contact lens case, and labeled 
with the subject identification and stored in Unisol non-preserved saline. 
10 Statistical Analysis  
10.1 Statistical analysis 
Summary statistics will be produced, (e.g., mean, standard deviation), by the principal investigator. 
Differences between lenses will be compared using Paired t-tests. Paired t-tests /analysis of variance 
for normal (interval/continuous) data, Wilcoxon’s signed ranks test for non-normal (ordinal) data, chi-
squares test for nominal data. A Binomial test will be used to evaluate lens preference questions. All 
participants who are evaluated in the study will be used in the analysis. In the event of missing data 
individual number of points will be excluded in the analysis and not extrapolated from the collected 

Confidential 
EX-MKTG-146 Clinical Evaluation of Biomedics 1 day Toric and MyDay toric 
18 
data. The critical alpha level for statistical significance will be set at p ≤ 0.05, with adjustment for 
multiple comparisons. 
10.2 Sample size 
Figure 1 shows the sample size calculation for a paired t-test, (alpha=0.05), in order to detect a 
difference in mean subjective handling scores between lenses. Assuming a standard deviation of 1.2, 
a sample size of about 37 completed subjects provides 84% power to detect a difference in subjective 
handling ratings of 0.6 points on a 0-10 scale. However, in this study a scale of 0-100 will be used. In 
order to account for potential subject dropouts or AEs, around 45 subjects will be enrolled with the aim 
to complete 37.
