Comparing two cataract lens types in the same person
Part of Eyes & vision clinical trials.
This study compares two different cataract (intraocular) lens options in each eye of the same person. It aims to see which lens gives better distance vision after standard cataract surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are planning cataract surgery on both eyes with an implanted focusing lens (posterior IOL).
- You are between ages 50 and 100.
- You have irregular astigmatism, and the study needs specific lens types to match your condition (Acrysof IQ Vivity or IC-8 Apthera).
- You should be able to see well enough in both eyes for driving-range vision after surgery (around 20/25 or better).
- You have no prior eye surgery or eye injury before this cataract surgery.
- You are not pregnant or breastfeeding, and you must not be able to become pregnant.

This study compares different types of artificial lens implants (including toric lenses that correct astigmatism) during cataract surgery. It may help find which lens options work best for your vision and astigmatism correction.
This trial compares the Clareon PanOptix lens with another similar multifocal lens to see which provides better vision after cataract surgery. It has two stages: one for people who already had the lenses implanted, and one for those who are planning to have cataract surgery.
This study tests two types of intraocular lenses (IOLs) used in cataract surgery to see which one gives better visual function after the operation. It may help you see better at different distances without glasses.
This study compares two types of advanced intraocular lenses (IOLs) used during cataract surgery to see which provides better vision at multiple distances. It may help you achieve clearer vision without relying heavily on glasses after surgery.
This study compares two kinds of artificial lenses used in cataract surgery to see which one gives better vision. It may help you choose the lens that best suits your daily visual needs.
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.
