Comparing two marking methods for placing astigmatism-correcting lenses
Part of Eyes & vision clinical trials.
This study compares two ways of marking your eye before cataract surgery to help place a special lens (toric lens) that corrects astigmatism. It aims to see if a digital method works as well as the manual one, which could make the procedure more accurate and easier.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are scheduled for routine cataract surgery (no other eye problems).
- You have no irregular astigmatism or other conditions like glaucoma, uveitis, or previous eye surgery.
- You are able to have your eye measured with special devices (ARGOS or VERION) before surgery.

Other trials that look related to this one.
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 trial tests two different devices that measure your eyes before cataract surgery to see which one helps doctors choose the best lens implant. The goal is to get your vision as close to perfect as possible after surgery.
This trial compares two methods for calculating how much an artificial lens tilts or shifts after cataract surgery. It aims to find which method gives more accurate measurements.
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 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 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.
