background: photorefractive keratectomy is a popular mean to correct refractive errors of the eye and haze formation is one of the most important complications of the surgery. although standard dose of intraoperative mitomycin c has shown to be effective in reduction of this complication, potential side effects of mitomycin c promote us to show if the lower concentration of mitomycin c has t he...

PURPOSE To assess the long-term refractive outcomes of photorefractive keratectomy in myopia and myopic astigmatism. METHODS A retrospective study of 120 photorefractive keratectomy operated eyes with at least four-year follow-up (maximum of 96 months, mean follow-up 55 months). We divided patients into group 1 (G1) spherical equivalent (SE) up to -4.00 diopters (D) and group 2 (G2) SE >-4.00...

many studies have shown the effectiveness of photorefractive keratectomy (prk) in correction of vision in low and moderate myopia. to evaluate the results of 193-nm exeimer laser photorefractive keratectomy for highly myopic eyes, we reviewed refractive outcome of 43 eyes of 30 patients. most eyes were treated with 1-step operation, using a 6 mm optical zone. 43 eyes were treated for myopia, wh...
