Refractive Accuracy of "2WIN" and Portable Autorefractors

NCT04249505 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 708

Last updated 2021-07-23

No results posted yet for this study

Summary

Youth and some adults have photoscreening refractions and hand-held auto refraction before cycloplegia refraction during new and follow up eye examinations. Vector math is applied to each refraction to determine how closely the hand-held "dry" devices match actual refraction.

Conditions

  • Refractive Error - Myopia Axial
  • Astigmatism
  • Accomodation
  • Visual Impairment
  • Hyperopia of Both Eyes

Interventions

DEVICE

"2WIN" Photoscreener

non-cycloplegia refraction by Adaptica "2WIN"

DEVICE

"Plusoptix A12"

non-cycloplegic refraction by "Plusoptix A12" photoscreener

DEVICE

"Retinomax"

non-cycloplegic refraction by "Retinomax K+" auto refractor
