BACKGROUND/AIMS Epithelial debridement for photorefractive keratectomy (PRK) is associated with pain, slower visual recovery, and may be aetiological in haze production. The aim of this study was to assess the clinical results of a new technique involving raising and replacing of an epithelial flap in photorefractive keratectomy. METHODS A prospective, non-randomised, comparative, paired eye ...

PURPOSE To determine predictive factors for intra-operative cyclotorsion in photorefractive keratectomy (PRK). METHODS A retrospective statistical analysis of medical records pertaining to 3,996 eyes undergoing PRK was conducted. Outcome measures of this study were the likely existence of statistically significant relations between diverse and potentially influential factors and the occurrenc...

human species and is relevant in clinical practice—to excimer laser photorefractive keratectomy (PRK) in particular. Due to the complexity of the underlying physiological mechanisms, there is no single definition that applies to all aspects of ocular dominance. Nevertheless, a clinically useful definition would be, “The dominant eye is the eye that is preferred in monocular viewing or in pointi...

PURPOSE To report the clinical, confocal scan, and histopathologic features of nocardia keratitis in a patient who developed bilateral infection following photorefractive keratectomy (PRK). CASE REPORT A 23-year-old woman underwent bilateral PRK for low myopia. On postoperative day 3, dense central stromal infiltrates were noticed in both eyes. Empirical antibiotic therapy was initiated which...

PURPOSE Stereopsis, as a part of visual function, is the ability of differentiating between the two eyes' views (binocular disparity), due to the eyes' different positions. The aim of this study was to compare stereoscopic vision before and after photorefractive keratectomy (PRK) in myopia. METHODS In a prospective interventional case series study clinical trial, forty-eight myopic individual...

Materials and Methods: This retrospective study was conducted at Laser Vision Center, Model Town, Lahore. It comprised of 200 patients(400 eyes) that underwent PRK on Summit Apex Plus excimer laser from 20 Feb 2004 to 3 June 2005. All consecutive patients with complete relevant data were included in the study. Three months postoperatively, the uncorrected visual acuity and complications in each...

AIM To report the clinical presentation, surgical management, and outcome of retinal detachment following excimer laser. METHODS Retrospective analysis of retinal detachments observed in 11 eyes of 10 myopic patients who had previously undergone photorefractive keratectomy (PRK) or phototherapeutic keratectomy (PTK) by excimer laser. RESULTS Symptoms of visual loss in two eyes were initiall...
