Eye drop study to protect corneal cells after cataract surgery
Part of Eyes & vision clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 to 85 years old and scheduled for routine cataract surgery in one eye.
- Your cataract is moderate to advanced (grade 3, 4, or 5 on a standard scale).
- The number of cells on the inner layer of your cornea is at least 1000 per square millimeter.
- Your vision in the study eye is poor enough to need surgery (pinhole vision score of 35 letters or worse on an eye chart).
- You are not pregnant, breastfeeding, or planning to become pregnant, and you agree to use birth control if needed.
- You do not have active eye infections, glaucoma, severe cornea disease, or a history of cornea surgery in that eye.
- You do not take more than 500 mg of vitamin C supplements daily, and you have no recent history of kidney stones or severe kidney disease.

This trial tests whether taking vitamin C before and after cataract surgery can help protect the inner layer of the eye. It is for people aged 60 or older with hard, age-related cataracts who are having phacoemulsification surgery.
This Phase 2 study tests whether eye drops containing a medicine called N-acetylcysteine (NAC) can reduce damaging “reactive oxygen” in people with advanced Fuchs’ endothelial corneal dystrophy (FECD). It involves people who need a special cornea transplant (DMEK) at the same time as cataract surgery, aiming to improve cornea healing and vision.
This Phase 1 study tests how safe and tolerable an investigational treatment (EO2002) is in adults having cataract surgery. It also looks at whether the treatment can be given without causing harmful effects in people with reduced cornea cell counts.
This study tests a new anti-inflammatory eye drop (PRO-232) in people who had routine cataract surgery on one eye the day before. The goal is to see if it helps control swelling and pain without problems.
This study tests a new eye drop medicine to see if it is safe and how the body handles it. It is for healthy adults only, not for treating a condition.
This trial tests three different anti-inflammatory eye drops to see which works best for pain and swelling after cataract surgery. You may join if you are scheduled for cataract surgery only, and you can apply the drops yourself or have help.
