Testing a formula for laser eye surgery astigmatism correction
Part of Eyes & vision clinical trials.
This study develops a formula to help surgeons correct astigmatism (blurred vision from curved corneas) during a laser eye surgery called LASEK. If you're eligible, your surgery may be more precisely tailored to your eye shape.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are at least 18 years old
- Your nearsightedness ranges from -0.50 to -10.00 diopters (mild to severe)
- Your astigmatism ranges from -1.50 to -5.00 diopters
- Your prescription has been stable (changed less than ±0.50 D) for at least one year
- Your cornea (front of eye) has normal shape on imaging and is thick enough for surgery (>500 μm or predicted remaining layer >280 μm)
- Your eye pressure is below 21 mmHg

This study compares a new type of laser surgery (ray-tracing guided) to three other standard laser methods for correcting nearsightedness with or without astigmatism. It aims to see which approach provides the best vision 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 compares two types of LASIK surgery to correct nearsightedness and astigmatism. It may help if you have healthy eyes, are 22 or older, and have a stable prescription within a certain range.
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.
This study tests a newer version of LASIK eye surgery to correct nearsightedness and astigmatism. The researchers want to see if this laser approach is safe and effective for people who are eligible.
This trial compares two ways of mapping your eye to guide LASIK surgery for people with nearsightedness and mild astigmatism. It looks at how well vision (especially best-corrected vision) does after surgery one month later.
