Conditions

Cataract Senile

Brief summary

Modern day cataract surgery isn't just a rehabilitative procedure anymore but rather aims at improving a patient's quality of life by reducing the need for spectacles in everyday life to a minimum. One way of achieving this goal is by using different lens technologies, such as a monofocal lens paired a lens with EDOF technology, as EDOF lenses provide an enhanced depth of focus by creating a single elongated focal point. As this mix-and-match is well established, the aim of this study is to compare the monofocal lens cohort to the EDOF lens cohort and evaluate visual acuity and patient satisfaction.

Interventions

PROCEDUREIOL Implantation:EDOF lens

A EDOF lens is implanted in the dominant eye

PROCEDUREIOL Implantation: Monofocal lens

A monofocal lens is implanted in the non dominant eye.
