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...

OBJECTIVE To evaluate the safety and efficacy of bitoric laser in situ keratomileusis (LASIK) for the correction of simple myopic and mixed astigmatism. DESIGN Retrospective, single-center, and noncomparative case series. PARTICIPANTS Eighty-six eyes of 56 patients were analyzed for this study. Six-month and 1-year follow-up data were available on 86 eyes and 72 eyes, respectively. Eyes wer...

Purpose: To describe the thickness profiles of full retinal and outer layers (ORL) at macula in healthy young adults, associations with best-corrected visual acuity (BCVA). Methods: In total, 1604 participants (19-30 years) underwent an eye examination that included measurements their BCVA, axial length, autorefraction. The foveal pit nine Early Treatment Diabetic Retinopathy Study macular regi...

PURPOSE To compare the visual acuity and contrast sensitivity in eyes with the AcrySof ReSTOR multifocal intraocular lens (IOL) (Alcon) and eyes with the monofocal AcrySof SA60AT IOL. SETTING Policlinico Umberto I, Department of Ophthalmology, Rome, and private clinical practice, Rome, Italy. METHODS One hundred eyes had phacoemulsification cataract extraction and implantation of a ReSTOR m...

Neural changes that result from disruption of normal visual experience during development are termed amblyopia. To characterize visual deficits specific to astigmatism-related amblyopia, we compared best-corrected visual performance in 330 astigmatic and 475 non-astigmatic kindergarten through 6th grade children. Astigmatism was associated with deficits in letter, grating and vernier acuity, hi...

purpose : to review the visual outcome and complications of deep anterior lamellar keratoplasty (dalk) using the big-bubble technique in patients with corneal ectasia methods : eighteen consecutive patients with keratoconus or post-lasik ectasia with poor spectacle-corrected visual acuity and/or contact lens intolerance were enrolled in this study between october 2005 and september 2006. dalk b...

OBJECTIVE To compare the effects on visual acuity of laser treatment (LT), photodynamic therapy (PDT) with verteporfin, and intravitreal bevacizumab treatment in patients with juxtafoveal choroidal neovascularization secondary to pathologic myopia. METHODS This prospective randomized clinical investigation enrolled 54 patients, who were divided into 3 groups receiving PDT, LT, or intravitreal...

PURPOSE To report the visual outcomes and complications of congenital cataract surgery with primary intraocular lens implantation in microphthalmic eyes of children younger than 4 years of age. METHODS This retrospective interventional case series included 14 microphthalmic eyes from 10 children who underwent congenital cataract surgery with primary intraocular lens implantation younger than ...
