In the last two decades, corneal laser surgery has become a common procedure to correct medium-low refractive defects. It consists of reshaping geometry by means in order present error. this work, we compare opto-mechanical performance procedures: Photorefractive Keratectomy (PRK) and Small Incision Lenticule Extraction (SMILE).

PURPOSE To compare changes in the corneal wavefront aberrations after photorefractive keratectomy and laser in situ keratomileusis. METHODS In a prospective randomized study, 22 patients with bilateral myopia received photorefractive keratectomy on one eye and laser in situ keratomileusis on the other eye. The procedure assigned to each eye and the sequence of surgery for each patient were ra...

PURPOSE To evaluate the efficacy of unilateral photorefractive keratectomy to correct anisometropia induced by retinal detachment surgery. METHODS Photorefractive keratectomy was performed in 10 eyes of 10 patients with anisometropia induced by previous retinal detachment surgery. The Aesculap Meditec MEL 60 excimer laser was used. RESULTS Preoperative mean spherical equivalent refraction w...

PURPOSE We investigated the keratocyte response and stromal remodeling after corneal incision and photorefractive keratectomy to understand the histophysiological and immunohistochemical differences between these two types of surgery. METHODS Corneal incision or photorefractive keratectomy was performed in rabbits or rats. Then we chronologically observed the histological changes and the chan...

This is a report of two brothers who underwent bilateral photorefractive keratectomy and developed bilateral peripheral corneal infiltrate on the third day following surgery. The patients were treated with antibiotics and low concentration steroid until negative culture was reported 48 h later, when intensive topical steroid was started. The infiltrate resolved by day 10 with residual subepithe...

purpose: to evaluate the corneal endothelial cell density and polymegathism one year after laser assisted keratomileusis using mitomycin c. methods: one hundred and three eyes from 52 patients who underwent laser assisted sub-epithelial keratomileusis using mitomycin c 0.02% for 30 seconds entered this study. corneal endothelial cells were evaluated using specular microscopy before and one year...

This research focuses on four cases of patients having undergone eximer laser photorefractive surgery who were diagnosed with adenoviral keratoconjunctivitis during the postoperative period and who later developed epidemic keratoconjunctivitis (EKC)-like keratitis. Two of the patients had undergone laser-assisted subepithelial keratectomy (LASEK), one had undergone laser in situ keratomileusis ...
