PURPOSE To evaluate prospectively the long-term safety, efficacy, and visual performance following photorefractive keratectomy (PRK) for hyperopia using an erodible mask and axicon lens system. METHODS Eighteen eyes of 9 patients with a mean preoperative spherical equivalent refraction of +2.26 +/- 0.82 D (range, +1.13 to +4.00 D) underwent PRK with the Summit Apex Plus excimer laser followin...

METHODS: Retrospective analysis of data from patients who underwent toric iris-fi xated pIOL (Artifl ex® and Artisan®) implantation in Centro Hospitalar Lisboa Central between 2009 and 2013. Th e main parameters evaluated were best corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), manifest refraction, intraocular pressure (IOP), central endothelial cell count (ECC) and complicat...

PURPOSE To evaluate the feasibility and efficacy of mini-scleral design (MSD) contact lenses to treat keratoconus patients who were unsatisfied with the results of corneal inlay. METHODS In this prospective interventional case series, 9 eyes of 6 keratoconus patients who were unsatisfied with the results of corneal inlay were fitted with MSD contact lenses. Demographic data, uncorrected visua...

We investigated the visual acuity of homeless people in Toronto and assessed the relationship of visual acuity to several determinants of health including age, education, attitudes and length of time in the homeless state. An interview questionnaire and a best-corrected near and distant visual acuity exam were conducted in a population of homeless men who were residing at the Good Shepherd Cent...

BACKGROUND Visual outcome following repair of post-traumatic corneal perforation may not be optimal due to presence of irregular keratometric astigmatism. We performed a study to evaluate and compare rigid gas permeable contact lens and spectacles in visual rehabilitation following perforating corneal injuries. METHOD Eyes that had undergone repair for corneal perforating injuries with or wit...

purpose : design and establishment of persian near reading card for clinical use and practice methods : at first, card dimension, word and character size and specifications were calculated. then, english near reading card, richmond product inc, was considered as a template. context and syntax contribute to reading accuracy and efficacy of the richmond card was considered for designed persian ca...

Here we report a case of unexplained sudden visual loss after removal of silicone oil for rhegmatogenous retinal detachment repair. A patient with visual loss in one eye after removal of silicone oil was investigated with best-corrected Snellen visual acuity assessment, fundus biomicroscopy, optical coherence tomography, color fundus photograph, fluorescein angiography, electrophysiologic exami...

PURPOSE To evaluate the relative efficacy of subthreshold micropulse diode laser versus conventional laser photocoagulation for the treatment of diabetic macular edema. METHODS A comprehensive literature search was conducted to find relevant randomized controlled trials (RCTs). Efficacy estimates were determined by comparing weighted mean differences of the mean change of best-corrected visua...

BACKGROUND To describe clinical outcomes in a series of patients with tractional cystoid macular edema, a variant of vitreomacular traction syndrome. METHODS Twelve consecutive patients (15 eyes) with tractional cystoid macular edema of maximum diameter of ≤550 μm and presenting corrected-distance visual acuity of ≤0.3 (Snellen ≥20/40) were studied. Each patient underwent ophthalmic examinati...
