PURPOSE To assess the visual results after bilateral implantation of the bifocal Acri.LISA 366D intraocular lens (IOL) (Acri.Tec AG). SETTING Fernández-Vega Ophthalmological Institute, Oviedo, Spain. METHODS Eighty-one patients had bilateral implantation of the distance-dominant bifocal Acri.LISA 366D IOL in a prospective study. Monocular and binocular best corrected distance visual acuity ...

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...

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...

purpose: to determine the effect of occluding a normal eye on visual acuity, contrast sensitivity and stereopsis in amblyopic school children. methods: amblyopic children from primary schools of region 2 in mashhad were identified and referred to optometry clinics of mashhad medical university through a screening program. informed consent was obtained from the parents. all subjects underwent an...

purpose: to evaluate visual outcomes after deep anterior lamellar keratoplasty (dalk) in patients with keratoconus. methods: in this interventional case series, patients with moderate to advanced keratoconus underwent dalk. inclusion criteria consisted of contact lens intolerance or poor spectacle-corrected visual acuity. dalk was performed using the big-bubble technique introduced by anwar and...

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: uncorrected visual acuity is the only variable measured in vision screening programs in many countries worldwide. the aim of this study was to calculate the sensitivity, specificity, and predictive value of the uncorrected visual acuity in the screening programs for the diagnosis of refractive errors. methods: in this cross-sectional study, of 4,157 students in the first year of primar...

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...
