Extended focus lens vs standard lens for cataract surgery
Part of Eyes & vision clinical trials.
This trial compares two types of artificial lenses implanted during cataract surgery: one that gives a wider range of clear vision (extended depth of focus) and a standard single-focus lens. It aims to see if the extended focus lens helps you see better at different distances without glasses.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older
- You have cataracts in both eyes that are bad enough to need surgery
- Your cornea (the clear front of your eye) has very little astigmatism (1.00 diopter or less)
- You have not had any prior eye surgery like LASIK or corneal transplants
- You do not have other eye conditions like severe dry eye, glaucoma, or macular degeneration that could affect vision
- You are willing and able to attend all study visits and follow the study plan

This trial compares two types of artificial lenses (intraocular lenses) used during cataract surgery: enhanced monofocal and extended depth of focus (EDoF) lenses. It aims to see which lens gives better vision for everyday activities.
This study compares two types of extended depth of focus (EDOF) lens implants to see how well they improve vision after cataract surgery. It may help people who need both distance and near vision without glasses.
This trial compares two different types of advanced lens implants that help you see at multiple distances after cataract surgery. It aims to find which one offers better vision for daily life.
This study tests a new type of lens implant that gives you a wider range of clear vision after cataract surgery. It uses a special laser to help remove the cataract, and the lens may help you see better at near, far, and in between without glasses.
This study tests a new type of lens implant that helps you see clearly at multiple distances after cataract surgery. It compares two ways to set the lens: one aiming for perfect distance vision in both eyes, and another that leaves one eye slightly nearsighted to improve reading vision.
This trial compares two types of artificial lenses (EDOF and monofocal) to see which gives better vision after cataract surgery combined with removal of an epiretinal membrane, a thin layer of scar tissue on the retina. The study aims to find which lens may improve how clearly you see at different distances.
