Comparison of U.S. FDA Premarket Approval Studies Between Ray Tracing-Guided LASIK with InnovEyes Sightmap Versus Topography-Guided LASIK Using Custom Ablation Treatment (T-CAT)

While TG-LASIK showed superior visual acuity outcomes, RT-LASIK was associated with higher contrast sensitivity; however, both platforms demonstrate excellent visual and refractive outcomes. The majority of published studies are consistent with FDA PMA trends, showing potential reductions in spherical aberration and higher rates of 20/20 or better visual acuity with RT-LASIK.
