A Prospective Randomized Comparison of SMILE Surgery to Ray Tracing-Guided LASIK Surgery
Status: Recruiting
Location: See location...
Intervention Type: Device
Study Type: Interventional
Study Phase: Phase 4
SUMMARY
Participants will undergo LASIK surgery in one eye using ray tracing guided technology in one eye and LASIK surgery in the other eye using wavefront guided technology. We are comparing outcomes between the two technologies as measured by self reported quality of vision and quality of life outcomes using validated questionnaires before and after surgery. We will also be comparing outcomes between the two technologies including measurement of low contrast visual acuity,and best spectacle corrected visual acuity.
