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.
