Study of two implantable astigmatism-correcting lenses
Part of Blood & lymphatic, Cancer, Eyes & vision, Immune system & allergy clinical trials.
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.
Summary written for real people, not researchers, by Clin2.

- You are 21 or older.
- Your glasses prescription has been stable for at least 12 months.
- If you wear contact lenses, you have had a stable prescription even after not wearing lenses for a few days or weeks.
- You have not had any eye surgery before (like LASIK or cataract surgery).
- You are willing to come to all follow-up visits and sign a consent form.

Other trials that look related to this one.
This study compares five different advanced lenses (that give a range of focus) with a standard single-focus lens for cataract surgery. It aims to see which lens provides the best overall vision.
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 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 different types of artificial lens implants (including toric lenses that correct astigmatism) during cataract surgery. It may help find which lens options work best for your vision and astigmatism correction.
This trial studies whether a specific, “viscoelastic-free” technique for implantable collamer lens (ICL) surgery is safe and works well for people with stable near-sightedness. It may help by improving the way the lens is inserted while closely monitoring eye safety and vision results.
This study tests a new type of artificial lens (called an accommodating IOL) that may help your eye focus on objects at different distances after cataract surgery. The lens is implanted during your standard cataract operation.
