Comparing laser eye surgery methods for nearsightedness
Part of Eyes & vision clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be between 22 and 50 years old.
- You must have nearsightedness with or without astigmatism, with a prescription between -2.00 and -9.00 in spherical equivalent.
- Your vision must be stable for at least 12 months (no major prescription changes).
- You must have good best-corrected vision (20/20 or better) in both eyes.
- You must not have had any previous eye surgery, and you cannot have certain eye conditions like keratoconus or severe dry eye.
- You must be willing to stop wearing contact lenses for a specific period before screening and surgery.

This trial compares two laser vision correction methods: SMILE surgery in one eye and LASIK surgery in the other eye. It is designed for people with mild to moderate nearsightedness and astigmatism to see which approach works better.
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 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 study tests how well a new type of LASIK (called ray-tracing-guided) improves vision in low light and how satisfied patients are with the results. It is for people with mild to moderate nearsightedness who want to stop wearing glasses or contacts.
This trial tests a laser device to correct nearsightedness and astigmatism by reshaping the cornea without creating a flap. It may be a good option if you have stable vision and want to reduce your need for glasses or contacts.
This trial compares two types of laser eye surgery (CLEAR and SMILE) to see which works better for nearsightedness and astigmatism. If you are eligible, it could help find the best option for your vision.
