Overview

Brief Summary

The purpose of this study is to evaluate differences in the depth of focus after implantation of a spherical or aspheric IOL in hypermetropic and emmetropic patients. After implantation of a spherical IOL hypermetropic patients may achieve a better depth of focus compared to emmetropic patients due to a larger amount of spherical aberrations.
