Wavefront Analyzes and Visual Performance of Three Multifocal Intra-ocular Lenses

University of Sao Paulo60 enrolled

Overview

The purpose of this study is to determine if differences in the design of multifocal intra-ocular lenses would mean different values of higher-order aberrations and different performance in objective parameters such as modulation transfer function.
