Cataract Senile
Conditions
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 mono- or bifocal 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 method is well established, the aim of this study is to compare the monofocal/EDOF cohort to the bifocal/EDOF cohort and evaluate visual acuity and patient satisfaction for both combinations.
