LAY LANGUAGE SUMMARY OR SYNOPSIS (no more than one paragraph)
The EyeQue Corporation has developed a hand-held device plus an app to measure the refractive error of the
eye. The refraction values will be captured using 2 devices
–
Auto refractor and EyeQue VisionCheck. These
refractive values will be used to prepare 2 sets of trial lens frames. n. Best-corrected visual acuity will be
assessed using the ETDRS eye chart. For each subject, BCVA LogMAR scores will be collected for OD, OS,
and OU for each of the 3 trial lens frames. They will also be asked a question regarding overall satisfaction with
visual acuity using each of the 3 trial lens frames. Subjects will be monitored for adverse events and adverse
device effects during the study
6.
SPECIFIC AIMS
1.
The primary objective of this study is to determine whether EyeQue VisionCheck is statistically non-
inferior to the phoropter as assessed by best corrected visual acuity (BCVA) for each eye independently,
measured using trial lens frames that correct the refractive error measured by each device, for the age
stratum 45 through 65 years.
2.
Assessing the similarity of refraction values (sphere, cylinder, axis) from the EyeQue VisionCheck
compared with the phoropter through comparative plots and Pearson correlations
3.
Determining whether EyeQue VisionCheck is statistically non-inferior to the autorefractor as assessed
by BCVA measured using trial lens frames that correct the refractive error measured by each device
4.
Determining whether EyeQue VisionCheck is statistically non-inferior to the phoropter as assessed by
BCVA measured using trial lens frames that correct the refractive error measured by each device, for
the age stratum 30 through 65 years.
5.
To evaluate the safety of EyeQue VisionCheck compared with the phoropter and the autorefractor
7.
BACKGROUND AND SIGNIFICANCE
Uncorrected refractive errors account for more than 40% of the major causes for visual impairment globally
The most common types of refractive errors include myopia, hyperopia, presbyopia, and astigmatism. When an
individual has an uncorrected refractive error, symptoms may include blurred vision, double vision, haziness,
squinting, headaches, and eye strain. Refractive error correction is accomplished through the use of eye glasses,
contacts, or refractive surgery. However, not all of the population has access to optometrists/ophthalmologists
and these diagnostic devices or can afford these exams. Additionally, for some instances it may be more
convenient to be able to obtain refraction values outside of the clinic.
The EyeQue Corporation is developing an inexpensive, portable, self-administered device to measure refraction
values that can be used outside of the clinic. This device is a monocular refraction system consisting of 3
components: a mobile app, a cloud-based processing platform, and the VisionCheck optical device that attaches
to a compatible smartphone owned/operated by the end user. The EyeQue app guides the subject through
interactive measurements with the EyeQue VisionCheck device in order to determine refractive error.

RESEARCH DESIGN AND METHODS
This is a single-center, open-label, prospective study in healthy volunteers desiring refraction for correction of
visual acuity to compare the EyeQue VisionCheck with the phoropter and autorefractor. Prior to enrollment of
study subjects, both the phoropter and autorefractor devices will be calibrated following standard practice
The subject will complete the following assessments and procedures at Screening to confirm eligibility.
Once eligibility is confirmed, the subject will be enrolled and proceed with study testing procedures. The
refraction values (sphere, cylinder, axis) for each subject (OD and OS) will be assessed using 2 additional
devices: autorefractor and the EyeQue VisionCheck. Subjects will be assessed with the autorefractor using
standard device methodology. The refraction values generated from the EyeQue VisionCheck, the
autorefractor, and the phoropter (during screening) will be used to prepare 3 sets of trial lens frames. Pupillary
distance, measured using the autorefractor, will be recorded for all subjects and will be used for preparation of
trial lens frames. All subjects will be trained on how to use the EyeQue VisionCheck device prior to initiating
testing. In order to obtain refraction values using the EyeQue VisionCheck, the subject will be required to take
1 practice test followed by a minimum of 3 saved tests for each eye using the EyeQue VisionCheck device and
mobile app. After completion of a set of tests (1 test for each eye), the subject may elect to save or discard that
set of tests. They may choose to discard for any reason which may include not following instructions, pressing
the wrong button in error, etc. Each test consists of the subject looking through the EyeQue VisionCheck
device and using the app controls to fully overlap red and green bars at 9 different angles. After completion of
all tests (1 practice test and 3 saved tests with each eye), the refraction values will be displayed on the mobile
app. These values will be used for preparation of the trial lens frames. If the EyeQue system determines that the
overall test results are unreliable, subjects may have to complete 3 additional tests per eye before the system
may be able to provide refraction values. Subjects will not be allowed to complete more than 6 saved tests and
1 practice with each eye. The system evaluates the statistical spread of the test results taken by the subject. If
the spread is too large, the results are considered to be unreliable and values will not be provided. Such spread
can be due to testing errors, improper instruction, etc. After the collection of refraction values from each device
(phoropter, autorefractor, and EyeQue VisionCheck), the 3 trial lens frames will be prepared and given to the
subject in a masked fashion. Best-corrected visual acuity will be assessed using the ETDRS eye chart. For each
subject, BCVA LogMAR scores will be collected for OD, OS, and OU) for each of the 3 trial lens frames.
Subjects will also be asked a question regarding overall satisfaction with visual acuity using each of the 3 trial
lens frames. Subjects will be monitored for adverse events (AEs) and adverse device effects (ADEs) during the
study
The EyeQue VisionCheck is a self-administered, portable, monocular refraction system consisting of 3 main
components: a mobile app, a cloud-based processing platform, and the VisionCheck optical device that attaches
to a compatible smartphone owned/operated by the end user. The EyeQue app guides the subject through
interactive measurements with the EyeQue VisionCheck device in order to determine refractive error. The
device and mobile app operate on the inverse Shack-Hartmann principle described in patent US 8783871 B2,
“Near Eye Tool for Refraction Assessment” (Pamplona V, US Patent, 2014).
The EyeQue VisionCheck device
is manufactured for EyeQue Corporation.
This device is considered a nonsignificant risk medical device study that is subject to abbreviated
investigational device exemption (IDE) regulations, and exempt from the requirement to submit an IDE
application.
The study will be conducted in accordance with GCP as contained in the US CFR governing the protection of

HUMAN SUBJECTS
Approximately 200 subjects will be enrolled in this study to achieve a minimum of 100 evaluable subjects. The
initial cohort included 39 subjects; therefore, approximately 160 additional subjects will be enrolled in the
study. Subjects will be enrolled to obtain a population of approximately 35% in the age range of 30 through 44
years and approximately 65% in the age range of 45 through 65 years. Subjects will be screened for study
participation and, if enrolled, will complete the testing procedures at the same visit.

14.
POTENTIAL RISKS
The device risk analysis and risk assessment were conducted in compliance with 21 CFR 820. Based on this
assessment, the EyeQue VisionCheck is non-invasive and considered a low-risk device that requires periorbital
surface contact. Even if the EyeQue VisionCheck is misused, the likelihood it will cause harm is low. The
comparators in this study, phoropter and autorefractor, are used as part of standard eye exams. Most of the
anticipated adverse effects are generally well tolerated and would be expected to occur infrequently. The risk
and impact of these adverse effects is low. Based on the design and the intended use of the EyeQue
VisionCheck, and given the low risk of potential adverse effects, this is considered a nonsignificant risk
medical device study that is subject to abbreviated investigational device exemption (IDE) regulations, and
exempt from the requirement to submit an IDE application.
The following adverse effects may potentially occur with the use of the EyeQue VisionCheck device itself, the
comparators, or the procedure used for the device:
• Transient blurred vision
• Transient dizziness
• Headache
• Transient eye irritation
• Superf
icial eye or periorbital infection
15. RISK MANAGEMENT PROCEDURES AND ADEQUACY OF RESOURCES
The following approaches have been used to minimize risk in this investigation:
• Subjects will be screened before receiving treatment to ensure they meet the protocol
-defined inclusion and
exclusion criteria. The inclusion and exclusion criteria have been developed to ensure appropriate subjects are
included in the studied population and subjects with confounding conditions or conditions that could put them
at risk are excluded from participation.
• The test articles (i
nvestigational and comparator devices) are intended for measuring refraction values and/or
accessing BCVA. To minimize risk during the evaluations, the site staff will be trained on all devices and
subjects will be instructed on how to use each device. The phoropter and autorefractor are both operated by the
site staff. The EyeQue VisionCheck device will be operated by the subject and subjects will be trained in
advance of completing testing with the device. The mobile app provides detailed instructions on how to operate
the EyeQue VisionCheck device. Detailed instructions for the site staff to provide to subjects about the EyeQue
VisionCheck are provided in the study operations manual.
• To minimize the risk of eye irritation or infection, the devices will be
sanitized between users.

Case Study – The New Engineer
Jeff was just hired by GSI, Inc. to be their Environmental and Safety Coordinator. This is Jeff's first position after completing his engineering degree. He had taken a course in safety engineering as part of his studies and felt confident that he could handle the job.
Management at GSI, Inc. has assured him that they are committed to maintaining a safe workplace. They have never had an individual dedicated to this task full-time. They will implement his recommendations if he can justify them.
As Jeff begins to get familiar with the operations, he spends considerable time on the production floor. He notices workers clean their tools before break with a liquid from an unmarked 55-gallon drum. They also use this liquid to clean residue from their skin. They use paper towels to dry their tools and hands, throw these towels in the trash, and head to the break room for a snack and/or smoke.
In talking with the workers, Jeff learns of some of…
