Laser vs. manual method for PRK eye surgery
Part of Eyes & vision clinical trials.
This study compares two ways to remove the outer layer of the cornea before laser vision correction (PRK): one uses a laser, the other uses a manual tool. The goal is to see which method helps patients heal better and see more clearly.
Summary written for real people, not researchers, by Clin2.

This study compares three laser eye surgeries—LASIK, SMILE, and PRK—to see which works best for people who have similar eye prescription needs. You may be a good fit if you’ve never had vision-correcting surgery before and you meet the eye-health safety checks.
This study compares two types of laser surgery for vision problems (PRK versus another approach called “WFO ablation”) to see which works better for clear sight. You may be a candidate if you meet specific eye measurements and can return for follow-up visits.
This study is collecting health information from people who have undergone a specific laser eye correction procedure (PTK-PRK) for nearsightedness with or without astigmatism. It aims to understand how well the treatment works and how safe it is.
This study compares a new type of laser surgery (ray-tracing guided) to three other standard laser methods for correcting nearsightedness with or without astigmatism. It aims to see which approach provides the best vision correction.
This trial tests a new LASIK technique called PRESBYOND to improve vision at all distances in people with presbyopia (age-related need for reading glasses). It uses the MEL90 excimer laser to reshape the cornea.
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.
