Comparing two types of laser eye surgery for nearsightedness
Part of Eyes & vision clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 22 years old or older
- You have nearsightedness between -1.00 and -8.00 diopters (a measure of lens power)
- You have astigmatism of 3.00 diopters or less
- Your eyes are similarly nearsighted — the difference between them is no more than 1.50 diopters
- Your eyes have similar levels of astigmatism — difference of 0.75 diopters or less
- You have healthy eyes (no very thin corneas, no keratoconus or other eye disease, no autoimmune disease, and not pregnant or nursing)

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 compares three laser eye surgeries—LASIK, SMILE, and PRK—to see which works best for people who have similar eye prescription needs. You may be a good fit if you’ve never had vision-correcting surgery before and you meet the eye-health safety checks.
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 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.
This study compares two types of laser eye surgery (SMILE and SMILE Xtra) to see which works better for treating nearsightedness. The goal is to help you see clearly without glasses or contacts.
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.
