Trifocal lens implant study for cataract or presbyopia
Part of Eyes & vision clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You need cataracts in both eyes or are getting lens replacement surgery.
- You have trouble seeing up close (presbyopia) or are farsighted.
- Your eye's natural curve (astigmatism) must be less than 1.00 diopter.
- You must not have other eye diseases like glaucoma or macular degeneration.
- You should be highly motivated to stop wearing glasses and willing to accept mild glare or halos at night.
- You are under 75 years old and not in a job that requires perfect vision (like a pilot or professional driver).

This study tests a new type of artificial lens (called a trifocal IOL) implanted during cataract surgery. It is designed to give you clear vision at multiple distances, and the trial checks how well it works in people with typical eye shapes and low astigmatism.
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 compares two different trifocal toric intraocular lenses (special lenses that correct both near, far, and astigmatism) used during cataract surgery. Researchers want to see which lens gives better results for people with cataracts and astigmatism.
This study tests a special lens implant (toric lens) for people having cataract surgery who also have astigmatism. The lens corrects both the cataract and the astigmatism, potentially giving you clearer distance vision without glasses.
This study tests whether a small ring placed around the lens implant during cataract surgery helps keep the implant stable for people with high myopia (severe nearsightedness). It could lead to better vision and fewer complications after surgery.
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.
