title: Unilateral corneal ectasia after laser in situ keratomileusis in a patient with uncomplicated photorefractive keratectomy in the fellow eye.
abstract: We report a patient treated for low myopia with laser in situ keratomileusis (LASIK) in one eye and photorefractive keratectomy (PRK) in the fellow eye. Corneal ectasia developed in the LASIK-treated eye. Preoperative corneal pachymetry, topography, and attempted correction were similar in both eyes. In patients whose corneas may be predisposed to instability, PRK may be a safer alternative procedure than LASIK.
