NCT ID NCT07688681
First seen Jul 07, 2026 · Last updated Jul 08, 2026 · Updated 1 time
Summary
This study compares two types of artificial lenses used during cataract surgery, both designed to provide clear vision at far and intermediate distances. Adults having cataract surgery in both eyes are randomly assigned to receive either the Tecnis PureSee or the 1stQ Comfort Z-EDOF lens. The goal is to see which lens offers a wider range of clear vision and better overall satisfaction, helping doctors and patients make informed choices.
