Long-term results of photorefractive keratectomy for myopia and myopic astigmatism.
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...
متن کاملLong-term changes of the anterior corneal topography after photorefractive keratectomy for myopia and myopic astigmatism.
PURPOSE To analyze the anterior corneal topography changes after 8 years after photorefractive keratectomy (PRK) for the correction of myopia and myopic astigmatism. METHODS Sixty-six eyes (33 patients) underwent PRK using an excimer laser platform. Patients were subdivided into three groups: the low myopia (13 patients; range, -1.25 to -4.40 diopters [D]), the high myopia (13 patients; -4.50...
متن کاملPhotorefractive keratectomy for myopia and photoastigmatic keratectomy for astigmatism.
BACKGROUND We conducted a clinical trial to evaluate the efficacy and safety of excimer laser photorefractive keratectomy (PRK) and photoastigmatic refractive keratectomy (PARK) using the Nidek EC-5000 excimer laser. METHODS A total of 67 eyes from 47 patients whose average age was 35 years were enrolled in the study. The mean spherical equivalent of the manifest refraction before surgery was...

purpose: the aim of this study was to compare higher-order aberrations between personalized treatment (pt) versus personalized treatment advanced (pta) photorefractive keratectomy (prk) for myopia and myopic astigmatism. methods: in this clinical trial, 80 eyes of 40 patients who met inclusion criteria were enrolled. they underwent prk using pt or pta algorithm randomly. higher-order aberration...
متن کاملlasik retreatment for myopia and myopic astigmatism
purpose: to evaluate the results of laser in situ keratomileusis (lasik) retreatment in patients with postoperative regression. methods: in a retrospective interventional case series, 153 eyes of 113 patients who had undergone lasik retreatment for postoperative regression were evaluated. both initial lasik and retreatment were performed with a nidek: ec 5000 excimer laser, and flap was made w...
