Effect of Lens Presentation on the Clinical Oculomotor Assessment at Near

NCT02679313 · Status: WITHDRAWN · Phase: NA · Type: INTERVENTIONAL

Last updated 2025-05-31

No results posted yet for this study

Summary

This study will compare near clinical oculomotor parameters (heterophoria, vergence ranges, AC/A and accommodative findings) measured when lenses and/or prisms are introduced using three different instruments namely: (i) a standard manual phoropter, (ii) an electronic phoropter and (iii) a wearable adaptive refractor (VisionFit).

Conditions

  • Vision Disorders

Interventions

DEVICE

Phoropter

Each subject will be tested on 3 separate occasions using either the manual phoropter (American Optical 11625), electronic phoropter (Topcon CV-5000) or the wearable adaptive refractor (VisionFit). Oculomotor measurements, i.e., heterophoria, vergence ranges, AC/A and accommodative findings will be measured at each session using the different devices. Each session will be separated by a minimum of 24 hours and a maximum of 14 days.
