Abstract
Laser vision correction (LVC) has grown with tremendous speed over the past
decade. In addition to the choice of surface (photorefractive keratectomy, laserassisted
epithelial keratectomy, epi-laser in situ keratomileusis) or lamellar
(LASIK, femto-LASIK) treatments, the surgeon now has to select a laser profile
for myopic, hyperopic, or astigmatic treatment.
Wavefront-guided, wavefront-optimized, topography-guided and Q-factor
adjusted ablation are the most advanced and frequently used profiles in current
practice. Technical developments, clinical studies, and surgeon experience
should help in selecting the best profile.
This study characterizes distinctly the various ablation profiles with the use of
comparative studies emphasizing the advantages and disadvantages of each in
correlation to their outcome, safety and predictability. Thus highlighting the
prudent use of the different profiles to ensure optimum optical and visual
outcome of the refractive procedure.
