Lee WS, et al. - Researchers ascertained and compared the relationship between change in simulated keratometry (K) and degree of refractive correction in wavefront-guided (WFG) and wavefront-optimized (WFO) myopic laser-assisted in situ keratomileusis (LASIK) at the Byers Eye Institute, Stanford University. Compared to WFG LASIK, WFO LASIK required a smaller amount of corneal flattening for a given degree of refractive correction. For both, no significant difference was reported in the corneal curvature change for a given degree of refractive error between smaller and larger corrections.
