Comparing two new cataract lens implants for distance and near vision
Part of Eyes & vision clinical trials.
This study compares two types of advanced intraocular lenses (IOLs), the Tecnis PureSee and the Comfort Z-EDOF, placed during cataract surgery. The goal is to see which lens gives better all-around vision, with the dominant eye corrected for distance and the non-dominant eye slightly under-corrected to help with reading.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 40 years or older with cataracts in both eyes that are ready for surgery.
- You have no prior eye surgeries like LASIK, cataract surgery, or glaucoma surgery.
- Your corneas are clear and shaped regularly (astigmatism no more than 4.5 diopters).
- The length of your eye (axial length) is between 21.5 and 26.5 mm.
- You have no significant eye diseases like advanced macular degeneration or glaucoma affecting central vision.
- You agree to the target vision plan: the dominant eye sees perfectly far, and the other eye is helped to see better up close.

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 trial tests new enhanced monofocal intraocular lenses (special lens implants) to see if they improve vision after cataract surgery. It is for people with age-related cataracts in both eyes who are otherwise healthy.
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 study tests a new type of cataract surgery lens that aims to give clear vision at multiple distances, possibly reducing the need for glasses. If you are having cataract surgery in both eyes, this trial may help you see better overall.
This study compares two types of artificial lenses (IOLs) used during cataract surgery to see which one gives better vision. It is for people who need cataract removal in both eyes and have healthy eyes otherwise.
This study compares two types of multifocal intraocular lenses (IOLs) used during cataract surgery to improve vision at multiple distances. It is for people with cataracts in both eyes who have not had previous eye surgery.
