Wavefront-guided LASIK Surgery Compared to Ray Tracing-Guided LASIK Surgery

Recruiting now · Not applicable

Conditions studied: Myopia, Astigmatism

In brief

We are enrolling participants aged 22 and older to have LASIK surgery in both eyes. We will perform wavefront-guided LASIK in one eye and ray tracing-guided LASIK in the fellow eye of each participant. We are trying to see if there are any differences in the efficacy between the two types of LASIK procedures.
