Comparing two toric lenses for cataract and astigmatism
Part of Eyes & vision clinical trials.
This study compares two types of advanced lens implants (Alcon Vivity Toric and RxSight LAL+) for people with cataracts and astigmatism. The goal is to see which lens gives better vision after surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 45 years or older and have cataracts in both eyes that need surgery.
- You have regular astigmatism (1.00 to 2.00 diopters) that can be corrected with a special lens.
- Before cataracts, you had good vision (20/25 or better) in each eye.
- Your pupils can dilate to at least 7 mm (about the size of a pencil eraser) in both eyes.
- You do not have other serious eye conditions like glaucoma, macular degeneration, severe dry eye, or a history of certain eye infections or surgeries.

This study compares two types of advanced artificial lens implants used during cataract surgery. It looks at how well people see after getting one type of lens in one eye and the other type in the other eye, compared to getting the same type in both eyes.
This study compares two types of artificial lenses placed during cataract surgery to see which one gives better vision for people with cataracts and astigmatism. You will receive the same type of lens in both eyes.
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 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 tests different artificial lens implants (called intraocular lenses or IOLs) to see which gives the best vision after cataract surgery. If you have cataracts in both eyes and need surgery, you may be able to join.
This study compares three types of toric lenses (lenses that correct both cataracts and astigmatism) to see how well they stay in place after surgery. It may help you choose the best lens for your cataract surgery.
