A Randomized Comparative Study of Topography-Guided Versus Wavefront-Optimized FS-LASIK for Correcting Myopia and Myopic Astigmatism

Abstract

TCAT in virgin eyes induced less corneal optical path difference, fewer higher order aberrations, and less coma than WFO LASIK. However, TCAT was not as accurate as WFO, especially in astigmatism correction. A better compensation method for TCAT is warranted. [J Refract Surg. 2019;35(9):575-582.].
