[Functional vision training after MIOL implantation].

In a prospective and intraindividually comparative study, we investigated visual performance after implantation of two multifocal intraocular lenses. Eight patients received the ReSTOR (Alcon) bilaterally, and eight patients received the Tecnis ZM900 (AMO). The nondominant eye of each patient was trained based on the concept of perceptual learning using orientation discrimination of near-vertical bars. The fellow eye served as a control. After 3 h of training distributed over 2 weeks, the mean improvement of orientation discrimination in the trained eyes was 44%, which was significantly higher compared with the control eyes (9%). Moreover, contrast sensitivity and near vision under different contrast levels showed a significant benefit of training. These results support the concept of improving visual function by training after multifocal lens implantation. The superior function of the trained eyes was still present at the 6-month follow-up.
