Study to Evaluate the Reliability, Validity and Safety of Subjective Mobile Refraction
Study Details
Study Description
Brief Summary
This study evaluates the reliability, validity and safety of a self administered, subjective refraction test via a mobile medical app (GoEyes) as compared to standard of care subjective manifest refraction performed by a health care provider, in subjects who have no known ocular disease or condition other than refractive error.

Detailed Description
GoEyes is a Mobile Medical Application, which can be downloaded to a smartphone and is being developed as a self -administered subjective refraction examination that measures the refractive error of the user's eyes in the home environment without any contact or help from health care professionals.
The Study will be conducted in 2 parts; Part A and Part B.
Approximately 59 participants will be enrolled In Part A. Part A participants will have a GoEyes refraction test in clinic on two separate days and will also have a standard of care refraction test performed by a health care provider and best corrected visual acuity assessments.
Approximately 220 participants will be enrolled in Part B. Part B participants will self administer the GoEyes test at home on 2 separate days and will also have an in clinic standard of care refraction test performed by a health care provider and best corrected visual acuity assessments.

Outcome Measures
Primary Outcome Measures
- 90% Concordance for sphere power and cylinder power (monocular) [Baseline]
- Descriptive statistics for concordance of cylinder axis (monocular) stratified by cylinder power [Baseline]
- Monocular refractive outcomes [Baseline]
Lower confidence limit of ≥ 90% for concordance (for right and left eyes separately)
- Monocular visual acuity [Baseline]
Lower confidence limit of ≥95% (for right and left eyes combined)
- Proportion of out-of-range eye that are correctly excluded [Baseline]
- Incidence of Adverse Events in Part 1 [21 days]
- Incidence of Adverse Events in Part 2 [8 Days]
Secondary Outcome Measures
- Descriptive statistics for sphere power and cylinder power (monocular) [Baseline and Visit 2 (day 2-21 for part 1 and day 2-8 for part 2)]
- Descriptive statistics for cylinder axis (monocular) stratified by cylinder power [Baseline and Visit 2 (day 2-21 for part 1 and day 2-8 for part 2)]
- Descriptive statistics for concordance of monocular refractive outcomes (for right and left eyes separately [Baseline and Visit 2 (day 2-21 for part 1 and day 2-8 for part 2)]
- Descriptive statistics for monocular and binocular visual acuity (for right and left eyes combined [Baseline]
- Proportion of out of range eyes that are correctly excluded [Baseline and Visit 2 (day 2-21 for part 1 and day 2-8 for part 2)]
- Comparison of test and re-test measurements to Standard of Care (SOC) data [Baseline and Visit 2 (day 2-21 for part 1 and day 2-8 for part 2)]
- Rate of disagreement between GoEyes screening at home and in-clinic screening [Baseline]
