This study is comparing a new type of LASIK surgery called Ray-Tracing Guided LASIK to three other common vision correction surgeries: Keratorefractive Lenticule Extraction (KLEx), WaveFront Optimized LASIK, and Topography Guided LASIK. The goal is to see which surgery provides the best uncorrected vision (vision without glasses or contacts). You might be able to join if you are between 22 and 50 years old and have nearsightedness (myopia) or nearsightedness with astigmatism (blurry vision due to an irregularly shaped cornea). The study is currently unclear on its recruitment status, but plans to enroll 120 people in total.

Study design

This study is designed in three phases, comparing Ray-Tracing Guided LASIK to one other surgery in each phase. It is a randomized study, meaning which eye gets which treatment is decided by chance, and involves 120 participants.

What's involved

You will undergo refractive correction surgery for myopia or myopia with astigmatism. You will also have follow-up visits to measure your uncorrected visual acuity at 3, 6, and 12 months after surgery.

Compensation

Not stated in the trial record.

Follow-up

Your vision will be checked at 3, 6, and 12 months after your surgery.
