Measuring the Peripheral Optical Quality of The Eye

• Status: Completed

• Healthy volunteers: Accepted

Summary

The goal of the study is to quantify wavefront aberration profiles of the eye with and without contact lens across the visual field. This will enable us to investigate the impact of the aberration on retinal image quality.

Detailed description

The goal of this study is to investigate the effects of monofocal and bifocal soft contact lenses in the changes of peripheral optical quality and through-focus visual performance on real eyes. The goal will be accomplished by performing optical measurements using Shack-Hartmann wavefront sensor with and without the use of single vision and bifocal soft contact lenses.

Conditions

• Nearsightedness

Interventions

Type	Name	Description
