Current trends in advanced surface ablation

Experience has shown us that virtually all patients who are candidates for laser in situ keratomileusis can be candidates for surface ablation, but patients with specific ocular conditions, such as epithelial basement membrane dystrophy, superficial corneal scars, and previous radial keratotomy will have the best outcomes with surface ablation. Surface ablation and laser in situ keratomileusis are comparable in terms of safety and quality of vision. Wavefront-guided photorefractive keratectomy offers better acuity and less induction of higher order aberrations than wavefront-guided laser in situ keratomileusis.
