简要总结
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.
详细描述
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.
