Trifocal lens for cataract surgery
Part of Eyes & vision clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You need an artificial lens (called an IOL) with a power between +15.0 and +25.0 diopters for each eye, which your doctor will determine.
- You should have only low astigmatism (less than 1.00 D), meaning the shape of your eye is fairly smooth, not too misshapen.
- Your eye doctor must believe that you can achieve good vision (about 20/32 or better) after surgery when wearing glasses or contact lenses.
- You should not have significant corneal disease or other health issues that could make the surgery risky or affect the results.
- You should not want monovision (one eye for distance, one for near); this trial expects both eyes to be corrected for distance.

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 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 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 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 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 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.
