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.
