PURPOSE To compare the visual and refractive outcomes of laser epithelial keratomileusis (LASEK) and laser in situ keratomileusis (LASIK) for the treatment of low to moderate myopia. DESIGN Retrospective, nonrandomized, control-matched study. METHODS The charts of 2257 eyes that underwent LASEK or LASIK treatment were reviewed. Patients who were 21(More)
PURPOSE To evaluate the safety and efficacy of corneal collagen crosslinking (CXL) in patients with painful pseudophakic bullous keratopathy (PBK). SETTING University of São Paulo, São Paulo and Sadalla Amin Ghanem Eye Hospital, Joinville, Santa Catarina, Brazil. METHODS This prospective study included consecutive eyes with PBK that had CXL. After a 9.0(More)
OBJECTIVE To report the safety, efficacy, and predictability of LASIK in a presbyopic population and to examine possible differences between age groups. DESIGN Retrospective, descriptive, comparative consecutive case series. PARTICIPANTS Seven hundred ten eyes of 424 patients between 40 and 69 years of age who underwent LASIK by the same surgeon between(More)
PURPOSE The aim was to report the corneal higher-order aberrations (HOA), the topographic metrics, and the visual and refractive outcomes 2 years after performing collagen crosslinking (CXL) for progressive keratoconus. The correlation among corneal HOAs, topographic metrics, and visual acuity changes was also investigated. METHODS This is a prospective(More)
PURPOSE To determine whether implantation of a multifocal intraocular lens (IOL) with a lower addition (+3.00 diopters [D]) at the lens plane results in better intermediate visual acuity 1 year after surgery compared with a multifocal IOL with higher addition (+4.00 D). METHODS This prospective, randomized, double-masked study included 80 eyes from 40(More)
We describe a standardized technique of femtosecond (FS) laser arcuate resection (LAR) in which intersecting arcuate cuts are used to perform a wedge resection for the correction of high astigmatism. A simple formula was used to calculate the relative decentration of the arcuate cuts based on the radii of curvature and desired wedge width to be resected.(More)
PURPOSE To evaluate topography-guided photorefractive keratectomy (PRK) for correcting hyperopia and astigmatism after radial keratotomy (RK). METHODS Prospective study of 12 consecutive patients (19 eyes) who were treated with topography-guided PRK with 0.02% mitomycin C using an Asclepion-Meditec MEL-70 excimer laser with a 9.5-mm ablation zone. All(More)
PURPOSE To evaluate the postoperative pain after corneal collagen cross-linking (CXL). METHODS : This prospective study included 178 consecutive eyes of 135 patients with progressive keratoconus who underwent CXL at Sadalla Amin Ghanem Eye Hospital, Joinville, Brazil. Pain was assessed postoperatively using the need for analgesia with 30 mg of codeine(More)
We present a technique to manage iridoschisis. This technique for anterior iridectomy of the affected iris fibers avoids intraoperative obstruction of the phaco tip and prevents postoperative complications such as corneal decompensation and glaucoma. Before the capsulorhexis is created, a vitreocutter is inserted in the anterior chamber and used to cut the(More)
Congenital anomalies of the optic disc can be associated with intracranial vascular abnormalities. We report a 9-year old boy with morning glory disc anomaly in one eye and optic disc and infrapapilar choroidal coloboma in the other. His past medical history was remarkable for a transient ischemic attack. A magnetic resonance angiogram of the brain was(More)
