Summary

This study compares two types of special lenses (Rayone EMV and Vivinex Impress XY1-EM) used in cataract surgery to improve vision at different distances. About 100 adults with age-related cataracts will receive these lenses in both eyes. The goal is to see which lens provides better vision at arm's length, far away, and up close.
