Summary

More and more patients like to achieve complete spectacle independence after cataract surgery. Two possibilities that are particularly often used today are on the one hand multifocal lenses, and on the other hand the concept of monovision (in doing so one eye is adjusted for closeness and the other focuses for distance). The drawback with multifocal lenses is that some patients are bothered by glare phenomena, the disadvantage of monovision is that some patients lose a little of their stereo vision.

The aim of this study is a direct comparison of these two methods. Therefore 70 patients are included in 2 groups. In one group, patients receive on both sides a multifocal IOL with a near addition of +1.5 D and the patients in the second group receive monovision. One hour, 1 week and 3 months after surgery, patients are invited and tests for visual accuity are performed for near vision (40cm), intermediate vision (80cm) and distant vision (400cm). Furthermore, contrast sensitivity and stereopsis of patients is assesed. Additional measurements for detecting the tilt of the lens will be performed.
