Comparison of Moderate- to High-Astigmatism Corrections Using WaveFront–Guided Laser In Situ Keratomileusis and Small-Incision Lenticule Extraction

Abstract

Both procedures showed preferable outcomes in the correction of moderate and high astigmatism. However, high astigmatism was undercorrected after both procedures. Axial error of astigmatic correction may be one of the potential factors for the undercorrection.
