Light Filters in Intraocular Lenses (IOLs) and Its Influence on Colour and Contrast Vision.

Hospital Hietzing32 enrolled

Overview

Visible-light-filtering IOLs are implanted increasingly often in cataract surgery. Several studies examined the effect of light-filters on contrast and colour vision. However, the study outcomes were varying. The present study investigated the effect of two light-filtering IOL on colour perception and contrast acuity using highly sensitive measurement methods.

Prospective, randomized, double-masked study with intraindividual comparison. Implantation of a Polylens Y30 IOL in one eye and an Orange Series Model PC 440 Y in the contralateral eye.
