Testing a New Three-Zone Vision Lens for Cataract Surgery
Part of Eyes & vision clinical trials.
This trial tests a new artificial lens that aims to help you see clearly at three different distances—far, intermediate, and near—after cataract surgery. The goal is to reduce your need for glasses or contacts after the procedure.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your eyes need a lens power between +15.0 and +25.0 diopters (a measure of lens strength)
- You must have minimal astigmatism (corneal irregularity) in both eyes—less than 1.00 diopter
- Your doctor believes you can achieve good vision (roughly 20/32 or better) in each eye after surgery, even with best-corrected glasses or contacts
- You cannot have significant corneal disease that might affect your vision results
- You must be in good overall eye and general health, with no conditions that would make it unsafe to participate
- You must be willing to have both eyes set up for balanced, multifocal vision—not one eye for distance only

This trial tests a specific cataract replacement lens to see how safe it is and how well it improves vision. If you have cataracts in both eyes and are good candidate for cataract surgery, this lens may help you see more clearly after surgery.
This study tests a new artificial lens (LuxBoost IOL) designed to safely improve vision after cataract surgery in both eyes. It may be a good option if you have cataracts in both eyes, have healthy eyes with no prior surgery, and need a standard lens power.
This study looks at how well your vision works and how different cataract surgery lens choices perform. It may help researchers better understand what affects sight after cataract surgery.
This study tests a new type of trifocal lens implant to see how well it improves vision at all distances after cataract or lens replacement surgery. It may help you become less dependent on glasses.
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 trial tests two types of artificial lenses (IOLs) in people with high nearsightedness and cataracts. It looks at which lens works better for vision recovery.
