Background and Aim: Vision improvement and reduction of refractive errors are considered as important goals of cataract surgery. The purpose of this study was to evaluate residual refractive errors after cataract surgery in the patients with senile cataract in Shahid Rahimi Hospital in Khorramabad City between 2017 and 2018. Material and Methods: This cross-sectional study included 178 patients...
Purpose: To analyze the correlation of optical coherence tomography angiography (OCTA) findings with visual acuity (VA) in patients with branch retinal vein occlusion (BRVO). Methods: This cross-sectional study was performed on 20 eyes of 20 patients with unilateral BRVO involving the macula referred to the ophthalmology clinic of Rassoul Akram Hospital. OCTA imaging was conducted for all patie...
Background and Objective: Car accidents are the second leading cause of mortality in Iran. For safe driving, drivers require minimum acceptable visual acuity. In Iran, the accepted routine test to take driving license is Snellen vision chart, which is not adequate for visual acuity determination in real and natural environment. It seems that introducing a more sensitive and specific screening t...
purpose: to evaluate the efficacy and safety of the artisan phakic intraocular lens (piol) for the correction of high myopia. methods: in this prospective study of 22 eyes of 14 patients with high myopia, artisan piols (ophtec bv) were implanted. uncorrected visual acuity (ucva), best corrected visual acuity (bcva), refraction, astigmatism, safety, and predictability were analyzed. results: the...
A 41-year-old man was referred with a complaint of visual loss in his left eye and his best corrected visual acuity was 20/80. Slit lamp examination showed arborizing conjunctival vessels and dry eye. Fundus examination and fluorescein angiography revealed a non-ischemic central retinal vein occlusion. Cardiovascular, rheumatologic, and hematologic work up showed no abnormal findings. An ascert...
BACKGROUND The purpose of this study was to evaluate visual outcomes of arteriovenous sheathotomy for macular edema due to branch retinal vein occlusion (BRVO). METHODS The medical records of 45 eyes from 45 patients who had undergone vitrectomy surgery with arteriovenous sheathotomy for BRVO were studied. Forty-five eyes of 45 patients with a BRVO but without intervention were studied as the...
A central island is defined as a localized elevated area in corneal topography after excimer laser application for myopic correction. We experienced 15 cases of central islands developed 1 week after LASIK using VISX STAR on corneal topography. The uncorrected visual acuity and best corrected visual acuity were 0.52 +/- 0.22, 0.66 +/- 0.25 in central islands group and 0.69 +/- 0.19, 0.78 +/- 0....
PURPOSE To determine prevalence and causes of visual impairment, blindness, ocular disorders and cataract surgery outcomes in a low-income elderly population from a metropolitan area in the city of São Paulo, Brazil. METHODS Observational study where 801 individuals of 60 years and older underwent presented and best corrected visual acuity measurements as well as ophthalmologic examination. D...
PURPOSE To evaluate the effect of intravitreal bevacizumab on the visual and anatomical outcome in eyes with macular edema secondary to branch retinal vein occlusion. METHODS A retrospective, consecutive case series identified 53 consecutive patients with a branch retinal vein occlusion treated with intravitreal bevacizumab. Clinical variables were analyzed, including best-corrected visual ac...
PURPOSE To compare the results from manifest refraction using trial lenses and a standard visual acuity protocol to results from autorefraction for obtaining refractive error and best corrected visual acuity in patients enrolled in a randomized clinical trial. METHODS During a 4-month period, 29 patients with subfoveal choroidal neovascularization (CNV), who were enrolled in the Submacular Su...
