NCT ID NCT07721714
First seen Jul 23, 2026 · Last updated Jul 24, 2026 · Updated 1 time
Summary
This trial compares two types of laser eye surgery—SMILE and ray tracing-guided LASIK—in people with nearsightedness and astigmatism. Each participant will receive one technique in one eye and the other in the other eye, allowing a direct comparison. The goal is to see which method provides better vision and quality of life three months after surgery.

- Active substance
- laser eye surgery (SMILE and ray tracing-guided LASIK)
- What this could lead to
- If one technique proves superior, it could become the preferred option for people with nearsightedness and astigmatism, offering sharper vision and fewer side effects.
- What could go wrong
- This is a small, single-center trial, so results may not apply to everyone. Both procedures carry risks like dry eyes or glare, and the difference between them may be minor.
