PURPOSE To compare corneal reepithelialization, pain scores, ocular discomfort, and tear production after photorefractive keratectomy (PRK) and butterfly laser epithelial keratomileusis (LASEK). METHODS This prospective, randomized, double-masked study comprised 102 eyes of 51 patients who underwent laser refractive surgery. Each patient was randomized to have one eye operated on with PRK and...

purpose: to compare long-term results of excimer laser sub-epithelial keratectomy (lasek) and laser in situ keratomileusis (lasik) for low to moderate myopia. methods: in a comparative case series, visual outcomes in 415 lasik-treated eyes (212 patients) and 359 lasek-treated eyes (194 patients) with myopia ranging from -1.5 to -5 diopters (d) and astigmatism up to -2.75 d using a flying spot e...

PURPOSE To determine the incidence and the type of flap complications in our initial series of eyes undergoing laser in situ keratomileusis and the impact of microkeratome-related complications on best spectacle-corrected visual acuity. METHODS We reviewed the charts of the 630 consecutive eyes operated in the Refractive Surgery Department of Cerrahpasa Medical School, University of Istanbul,...

PURPOSE To compare the effect of Homatropine and Diclofenac eye drops for reducing pain after photorefractive keratectomy (PRK). METHODS This randomized, double-masked, interventional study included 32 patients (64 eyes) who underwent bilateral PRK. After operation, patients received Homatropine eye drops in one eye and Diclofenac eye drops in the fellow eye for 48 h. The level of pain was ev...

The history of refractive eye surgery is recent, but has seen rapid advancement. Older technologies, such as radial keratectomy, had the problem of overcorrection and epithelial complications. Newer technologies, such as photorefractive keratectomy, laser-assisted in-situ keratomileusis (LASIK) and laser-assisted subepithelial keratomileusis (LASEK), which require the use of laser, has revoluti...

PURPOSE The corneal change induced by refractive procedures influence both the postoperative refractive status and the ocular spherical aberration (SA). We evaluated changes in corneal SA after three types of surface ablation: phototherapeutic keratectomy (PTK), myopic photorefractive keratectomy (PRK), and myopic wavefront-guided laser epithelial keratomileusis (LASEK). METHODS Twenty-six ey...

PURPOSE To evaluate by impression cytology (IC) the corneal surface of live limbal tissue donor eyes for autograft or allograft limbal stem cell transplantation (LSCT). METHODS Twenty limbal donors were enrolled (17 for autograft LSCT and 3 for allograft). Impression cytology was performed before transplantation of superior and inferior limbal grafts and after the third postoperative month. ...

AIMS/BACKGROUND To evaluate epithelial wound healing and visual outcome of excimer laser photorefractive keratectomy (PRK) performed on high myopic eyes with contact lens intolerance due to dry eye. METHODS PRK was performed on two groups of patients with non-Sjogren's dry eye: group A (-6 D to -9.5 D, 11 patients, 17 eyes) and group B (-11.5 D to -19.5 D, 11 patients, 16 eyes) in an attempt ...
