Purpose: To invcsligatc the polcnlial bcnclit of a lnrgcr ablation zone lix myopic PRK Methods: We reviewed the charts ,of patients who were included in the prospective evaluation of the Summi: Technologies lasers (Waltham, MA) with a minimum of 6 months follow up. 30 eyes treated with the Omnimed excimer laser (ablation zone 6 mm) were compared to 30 matched eyes treated with the Excimed model...

Purpose: To evaluate. long term efficacy, safety and stability of PRK for low and moderate myopia. Methods: 110 patients were treated for myopia up to 6D with the Summit Excimed excimer laser. The optical zone was 5mm in all cases. Manifest t&action. refraction under cycloplegla, comenl haze and comeal topography werc studied at D15, 1. 3, 6. 12. and 24 months after the surgery. Results: 110 pa...

PURPOSE The purpose of this study was to document the prevalence of anisometropia, anisoastigmatism, and anisometropic amblyopia in patients with neurofibromatosis-1 (NF1) and to compare it with that in age- and sex-matched controls. METHODS Fifty patients with NF1 and 150 age- and sex-matched controls were examined in this study. Cycloplegic autorefraction was attempted on all patients <16 y...

Abstract Background Refractive errors and visual impairment in southernmost China have not been reported previously. We aim to investigate determine the age-specific prevalence of myopia, hyperopia, astigmatism, based on a large population cross-sectional study Hainan area tropical province China. Methods A population-based sample 31,524 children aged 6–15 years from was assessed. Non-cyclopleg...

PURPOSE To describe baseline refractive and ocular component measures in children with myopia enrolled in the Correction of Myopia Evaluation Trial (COMET). COMET is a multicenter, randomized clinical trial to evaluate whether progressive-addition lenses slow the progression of juvenile-onset myopia compared with single-vision lenses. METHODS Four hundred sixty-nine children with myopia betwe...
