- Conditions
- Refractive ErrorsVision Disorders
- Interventions
- Device: EQ103
- Registration Number
- NCT04693247
- Lead Sponsor
- EyeQue Corp.
- Brief Summary
This study is exploratory and examines whether the best-corrected visual acuities (BCVA's) from trial frames created with the refraction results obtained from a novel handheld optical device yields results similar to the ophthalmic refraction obtained from an autorefractor in healthy volunteers age stratum of 18 through 65 years.

- Primary Outcome Measures
Name Time Method Best corrected visual acuity (BCVA) for both eyes EQ103 vs Autorefractor for all participants Day 1 Tendency of, or achieving, statistical non-inferiority of EyeQue EQ103 BCVA's (reading an EDTRS chart) for each eye from (pooled) trial frames created with the refraction values compared with those of an autorefractor analyzed with all age groups.
- Secondary Outcome Measures
Name Time Method Best corrected visual acuity (BCVA) for worse eye: EQ103 vs Autorefractor for all subjects and age groupings Day 1 Tendency of, or achieving, statistical non-inferiority of EyeQue EQ103 BCVA's (reading an EDTRS chart for worse eye from trial frames created with the refraction values compared with those of an autorefractor analyzed within the following age strata.
