Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
