purpose: to assess the short-term effect of mitomycin-c (mmc) 0.02% on endothelial cell density and morphology after photorefractive keratectomy (prk) in patients with moderate myopia. methods: forty-two eyes of 21 participants with moderate myopia (range, -4.0 to -8.0 d) underwent prk with mmc 0.02% for 40 seconds. specular microscopy was performed preoperatively and repeated 6 months after su...

background: silicon hydrogel bandage contact lenses are used to enhance epithelial healing, control surface-generated pain, and prevent epithelial erosions after refractive surgery. considering the importance of faster reepithelialization in preventing complications of photorefractive keratectomy (prk) and the fact that the features and specifications of these commercially-available lenses are ...

This study describes a case of nodular epithelial hyperplasia and stromal alterations in a patient with keratoconus who was submitted to topography-guided photorefractive keratectomy (PRK) followed by corneal collagen cross-linking. Debridement of the epithelial nodule was performed. After a 2-year followup, a new topography-guided PRK was indicated.

Two patients developed corneal ectasia after photorefractive keratectomy (PRK). Case 1 had evidence of early keratoconus preoperatively, with manifest refractions of -4.00 +2.50 x 160 (20/20) in the right eye and -7.00 +3.00 x 180 (20/30) in the left eye; thin corneas (472 microm and 441 microm, respectively); and inferior paracentral steepening in the right eye and central steepening in the le...

PURPOSE To describe a case of choroidal neovascularization (CNV) following photorefractive keratectomy (PRK) to correct myopia. METHODS We performed PRK in both eyes of a 20-year-old girl to correct myopia. Refractive error was -4.75 -2.25 × 5 in the right eye and -5.00 -1.25 × 180 in the left eye. Metamorphopsia was noticed by the patient in the right eye one month after the surgical procedu...

PURPOSE To assess the effectiveness, safety, and comfort of transepithelial photorefractive keratectomy (PRK) using the Amaris laser platform. SETTING Ophthalmic Consultants of Beirut, Jal-El-Dib, Metn, Lebanon. DESIGN Comparative case series. METHODS Myopic eyes with or without astigmatism were treated by transepithelial PRK (study group) and compared with variable-adjusted eyes treated ...

purpose : to present the clinical features, biomechanical properties and management of a patient who developed unilateral corneal ectasia after photorefractive keratectomy (prk) case report : the patient was a 24-year-old man without any obvious preoperative risk factor for ectasia who underwent bilateral prk. four years after keratorefractive surgery, the patient presented with loss of visual ...
