Abstract The ability to measure the wavefront aberration in the human eye more than a decade ago by Liang and associates . at the University of Heidelberg, Germany, inaugurated a new and revolutionary era in refractive surgery. Ocular wavefront aberrations were subsequently thoroughly studied and linked to contrast sensitivity and visual symptoms. Laser corneal photoablation profiles were soon to correct ocular wavefront aberrations in addition to the spherocylindrical refractive error, Early results published by Seiler and associates by the turn of the new millennium were encouraging. . Custom laser-assisted in-situ keratomileusis (LASIK) has since been performed worldwide, including the United States after receiving the Food and Drug Administration (FDA) approval, initially for myopia and myopic astigmatism in 2002. Since then, many technologic improvements have been made to various custom laser platforms, and many studies have been published investigating the efficacy, predictability and safety of wavefront-guided LASIK, with emphasis on quality of vision. |
