Study Summary
The purpose of this study is to compare the binocular distance, intermediate, and near visual acuity of the Alcon Vivity and Bausch \& Lomb enVista IOLs. We hypothesize that the Alcon Vivity and Bausch \& Lomb enVista IOLs will have similar distance, intermediate, and near visual acuity. If the null hypothesis is rejected, then the visual performance of the IOLs may be different.
Primary Outcome
Mean logMAR best-distance corrected visual acuity at intermediate (66 cm) tested in binocular photopic conditions at 3 months.
Interventions
- DEVICE Neutral Aspheric Monofocal IOL
- DEVICE Extended Vision IOL
