Comparing eye alignment methods for astigmatism correction in SMILE surgery
Part of Eyes & vision clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 to 40 years old.
- You have nearsightedness with astigmatism that has been stable for at least 1 year.
- Your cornea is healthy and thick enough for SMILE surgery, as checked by your doctor.
- You can see 20/20 or better with glasses or contacts before surgery.
- Your astigmatism is at least 0.75 diopters in both eyes, and the difference between eyes is 1.00 diopter or less.
- You are willing to have SMILE surgery on both eyes on the VISUMAX 800 machine and follow the random assignment of which alignment method is used.

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.
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 trial tests if a newer laser machine (VISUMAX 800) works as well as the current standard (VISUMAX 500) for correcting nearsightedness. It may help decide if the newer technology offers better outcomes for patients.
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 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 laser eye surgery (SMILE and SMILE Xtra) to see which works better for people with high myopia. It aims to help you understand which option might give you the best vision correction.
