PURPOSE: The aim of the present study is to assess central corneal edema and visual recovery after cataract surgery performed according to two technologies: conventional ultrasonic and liquefaction (Aqualase®). METHODS:This is a prospective contralateral study in wich 20 patients with comparable preoperative conditions were submitted to cataract surgery were evaluated. Preoperative assessment involved complete ophthalmological examination and the study included patients with bilateral cataracts up to grade 2, according to the Lens Opacity Classification System II. The same cristaline fracture […]

Purpose: To continue the updating and improving process of the cataract surgery in Brazil, through recently pulled out and documented registries. In addition, we want to obtain data for a comparative analysis of the current national and international surgical trends. METHODS:In May 2007, data were obtained from 188 participants of a Congress of Cataract and Refrative Surgery who answered simple and multiple-response questions about cataract surgery. Data were analyzed by statistic means of Chi-square test and T test. RESULTS:95.8% of […]

OBJETIVO: Avaliar o edema corneano central e a recuperação visual após cirurgia de catarata realizada através de duas tecnologias: ultrassônica convencional e liquefação (Aqualase®). MÉTODOS: Estudo retrospectivo com análise contralateral, onde 20 pacientes se submeteram à facectomia sob condições pré-operatórias comparáveis. A avaliação pré-operatória envolveu exame oftalmológico completo com graduação da catarata de acordo com o Lens Opacity Classification System II, e foram incluídos no estudo pacientes com catarata nuclear bilateral até grau II. A mesma técnica cirúrgica foi realizada […]

PURPOSE: Compare the wavefront and contrast sensitivity of bilateral pseudophakic patients with aspheric in one eye and spheric intraocular lenses in the other. METHODS: This prospective, comparative, randomized study, double masked, included 32 eyes of 16 patients. A complete ophthalmic evaluation was done before, and after surgery at days 1,3, 7 and 90, and included best corrected visual acuity, the contrast sensitivity, under photopic and mesopic conditions, and aberrometry. Almost all exams were done monocularly with undilated pupils (aberrometry under […]

PURPOSE: To evaluate the outcome and safety of the transition from phacoemulsification performed by third year residents using peribulbar anesthesia to topical anesthesia. METHODS: Cases performed by third year residents from august 2004 to february 2005 were analyzed. Patients were operated under peribulbar (group I) and topical anesthesia (group II). Variables analyzed included patients age, sex, visual acuity under pinhole and complications. Patients with low visual acuity other than cataract were excluded from analysis. RESULTS: A total of 151 eyes […]

PURPOSE: To estimate if a complicated phacoemulsification is a risk factor for developing age related macular degeneration. METHODS: Retrospective case-control study with review of records of 1150 patients, that underwent phacoemulsification surgery between 1995 and 1999, performed by a single surgeon (T.C.) Qui square test, Fisher exact test, and Mann-Whitney test were used to perform statistical analysis. RESULTS: There were 224 participants who had cataract surgery on 297 eyes, and from this total, 240 were with no complication and 57 […]
