Ningxia, NingxiaAges 40–85 - NCT07694375RecruitingPhase 2
Eye drop study to protect corneal cells after cataract surgery
This trial tests an eye drop called CA201A to see if it can prevent loss of cells in the clear front layer of the eye (the cornea) after cataract surgery. The drop contains ascorbic acid, a form of vitamin C, and is given before and after the procedure to help protect the eyesight.
Deakin, Australian Capital TerritoryAges 18–85 - NCT07693205RecruitingPhase 4
Comparing two lens types for cataract surgery with astigmatism
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.
Sugar Land, TexasAges 22 years+ - NCT07672899Recruiting
Study on tRF-31 changes in age-related cataract patients
This study looks at a small RNA molecule called tRF-31 in people with age-related cataracts. Researchers want to see how it changes, which may help understand cataracts better.
Hangzhou, ZhejiangAges 18 years+ - NCT07658040Recruiting
Comparing two cataract lens implants: Clareon vs. Tecnis
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.
Gainesville, GeorgiaAges 18 years+ - NCT07648095Recruiting
Lacrifill treatment for dry eyes before cataract surgery
This trial tests whether a treatment called Lacrifill can help improve dry eye symptoms in patients preparing for cataract surgery. Lacrifill is designed to keep the eye surface moist and healthy during the surgical process.
Largo, FloridaAges 40 years+ - NCT06681688RecruitingPhase 1/Phase 2
Comparing two approaches to prevent cataract surgery complications
This study compares two ways to prevent complications after cataract surgery. One group gets a special combination of eye drops and a steroid injection before surgery, and the other group gets standard care. The goal is to see which approach leads to fewer problems after surgery.
Venice, FloridaAges 18 years+ - NCT06712758Recruiting

Eye fluid and tissue analysis in glaucoma and cataract
This study collects eye fluid and tissue samples during planned cataract or combined cataract-glaucoma surgery to analyze differences between people with and without glaucoma. It may help researchers understand eye disease better.
WarsawAges 18 years+ - NCT06048380RecruitingPhase 3
Ripasudil drops for FED patients having cataract surgery
This trial tests if ripasudil eye drops can help people with Fuchs' endothelial dystrophy (FED) during and after cataract surgery. It aims to see if the drops protect the eye's inner layer and improve recovery.

Common questions
- Are there clinical trials for cataract?
- Yes. Clin2 currently lists 149 recruiting cataract studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a cataract trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a cataract trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
