What the study is about

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.

Being studied: LASIK; LASIK

Conditions: Myopia; Astigmatism
