INTACS for high astigmatism in healthy corneas
Part of Eyes & vision clinical trials.
This trial tests a procedure called INTACS, which uses small plastic rings to reshape the cornea and reduce high astigmatism. It is for people whose corneas are healthy and not bulging or thinning.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must have a high degree of astigmatism (a high cylinder error) in your eye.
- Your cornea must be healthy and not bulging or thinning (no ectasia).
- This trial is testing a treatment for people with high astigmatism but without a condition called keratoconus or other corneal weakness.

Other trials that look related to this one.
This study checks how accurately eye measurements describe astigmatism (a focus-bending problem) using different exam modes. It may help improve how doctors assess astigmatism after cataract surgery so treatment planning is more precise.
This study tests tiny plastic rings (called Intacs) that are placed in the cornea to help reshape it and improve vision. It is for people with a condition called corneal ectasia, where the cornea thins and bulges, and who are otherwise facing a cornea transplant.
This trial tests whether prescription inserts placed in the cornea can improve day-to-day vision for people with keratoconus whose vision is getting worse and who have few options left. You may be able to avoid or delay corneal transplant depending on your cornea shape and thickness.
This study tests two types of implantable lenses that correct astigmatism (blurry vision from an irregularly shaped cornea). You keep your own natural lens, and the new lens is placed in front of it—no laser or lens removal needed. The goal is to see which lens works better and is safer.
This study tests whether making small cuts in the cornea can safely reduce high astigmatism (blurry or distorted vision) that remains after cataract surgery. If effective, it could improve vision without needing glasses or contacts.
This study tests whether combining tiny corneal cuts with a special adjustable lens can better correct astigmatism (an irregularly shaped cornea) during lens replacement surgery. It may help people who need cataract surgery and have astigmatism achieve sharper vision without glasses.
