New lens implant aims to sharpen vision for cataract patients

This study tests a special lens implant that corrects cataracts, presbyopia (need for reading glasses), and astigmatism (blurry vision from an irregularly shaped cornea). The goal is to see if this lens stays stable in the eye and provides good vision at all distances. About 100 adults aged 45 and older with cataracts or presbyopia and significant astigmatism are taking part. The study compares their results to those from an earlier study on a similar lens.
