Not Applicable
Completed
- Conditions
- Myopia
- Registration Number
- NCT05308069
- Lead Sponsor
- David A Berntsen, OD PhD
- Brief Summary
This study will evaluate changes in visual performance at different pupil sizes between a single vision soft contact lens and multifocal soft contact lens, and compare refractive error measured between these two lenses with an autorefractor and an aberrometer
