Comparing SMILE vs SMILE Xtra for nearsightedness
Part of Eyes & vision clinical trials.
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 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 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 study compares three different methods to correct nearsightedness: SMILE laser, ICL implantable lenses, and Wavelight Plus laser. The goal is to find which works best for you.
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.
