Comparing two laser platforms for myopia surgery
Part of Eyes & vision clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have mild to moderate nearsightedness (no more than -1.00 diopters of spherical error).
- Your astigmatism is -2.00 diopters or less, and the difference in prescription between your eyes is less than 1.00 diopter.
- Your vision with glasses is at least 6/12 (20/40) in both eyes.
- Your prescription has been stable (changing by 0.50 diopters or less per year) for at least the past year.
- If you wear contact lenses, you must stop wearing them at least 2 weeks before the initial measurement.
- You have no irregular astigmatism, keratoconus, or other active eye diseases, and have not had prior corneal surgery or trauma in the area of the laser treatment.

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 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 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.
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 treating nearsightedness. The goal is to help you see clearly without glasses or contacts.
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.
