Laser showdown: which eye surgery fixes mixed astigmatism best?
NCT ID NCT07481227
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compared two types of laser eye surgery—FS-LASIK and single-step TransPRK—for correcting mixed astigmatism, a condition where the eye's shape causes blurry vision at all distances. Thirty-nine people received one of the two procedures, and researchers measured their vision and prescription afterward. The goal was to see which surgery provides better visual outcomes.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Femtosecond laser-assisted LASIK and single-step transepithelial photorefractive keratectomy (laser eye surgery procedures)
- What this could lead to
- If successful, this could help doctors choose the best laser surgery for people with mixed astigmatism, leading to clearer vision without glasses.
- What could go wrong
- This is a small, completed study with only 39 participants, so results may not apply to everyone. Both procedures carry standard risks like dry eyes or under-correction.
