A Comparison of Induced Astigmatism in Conventional and Wavefront-guided Myopic LASIK Using LADARVision4000 and VISX S4 Platforms

Abstract

Wavefront-guided ablation is associated with higher surgically induced astigmatism and larger astigmatic axis shift on the VISX platform as compared to the LADAR CustomCornea and the LADAR and VISX conventional platforms. Care should be emphasized mainly during registration/alignment to minimize surgically induced astigmatism in wavefront-guided LASIK.
