Eye Surgery Approach for Nearsightedness With Specific Eye Alignment
Part of Eyes & vision clinical trials.
This study compares two different computer-guided surgical techniques for correcting nearsightedness using a laser eye procedure called SMILE. The research tests whether adjusting for your eye's natural alignment during surgery affects your vision results.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Age 18–40 years old with stable glasses prescription for at least 1 year
- Nearsightedness or nearsightedness with astigmatism (blurred vision at all distances) within the range treatable by SMILE surgery
- Healthy cornea (clear front layer of eye) with normal thickness for surgery
- Best vision with glasses or contacts of 20/20 or better before surgery
- Specific eye alignment measurement (kappa angle) showing offset of at least 0.20mm in either direction
- Able to attend all follow-up visits and cooperate fully during surgery and recovery

This study tests whether a small adjustment during laser eye surgery for nearsightedness improves your vision outcomes. You'll be randomly assigned to receive either standard surgery or surgery with a minor compensation adjustment, and researchers will compare how well you see afterward.
This study compares two ways to align lasers during SMILE surgery to treat astigmatism (blurry vision from an irregularly shaped cornea). The goal is to find which method gives better vision correction with fewer side effects.
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 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 trial studies how well the SMILE laser procedure works to correct very high nearsightedness. It may help people with strong focusing power problems, as long as their eye measurements and cornea shape meet the study limits.
