With aspherical intraocular lens (IOL), phakectomy could be more than removal of cataract, it also could means an improvement in optical quality of the eye. In this article, recently published studies on aspherical IOLs and exams to access optical quality were reviewed.

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 […]

PURPOSE: To assess the influence of some forms of lenticular opacification in the Amsler grid test among patients suffering from senile cataract. METHODS: Randomized, prospective interventional trial. Two hundred patients with senile cataract were evaluated with Amsler grid, measurement of best corrected visual acuity for near distance and far distance, biomicroscopy of the anterior segment and macular region. RESULTS: With a two months minimum of follow-up, the average visual acuity after surgery for far distance among the 200 patients was […]

We describe a case of painless progressive loss of vision in a 15 years old male patient with Alport syndrome and diffuse Leiomyomatosis. After a comprehensive history and ocular examination, a diagnosis of bilateral posterior subcapsular cataracts was given. Patient underwent cataract extraction. His best corrected post-operative visual acuity was 20/25 in both eyes. We conclude that posterior subcapsular cataracts may lead to painless and progressive loss of vision in patients with Alport syndrome and Diffuse Leiomyomatosis.

PURPOSE: To identify aspects of the image test to arrive at the sure diagnosis of intumescent white cataract. METHODS: Two groups of eyes with white and nigra cataracts were studied using clinical and laboratorial criteria. RESULTS: The width of the lens > 5.36mm and its spherical aspect are the two data that provided us with a sure diagnosis of intumescent white cataract. CONCLUSION: The use of the image test provides data for the sure diagnosis of intumescent white cataract.

INTRODUCTION: Congenital cataract is an important cause of poor visual acuity and amblyopia, with an incidence of 0,4%. Surgical approaches in children present many advances through the years, such as intraocular lenses implantation and others thechniques, wich results in better visual outcomes and prevention of amblyopia. PURPOSE: To report the early outcomes of a series of cases submited to different surgical techiniques for pediatric cataract, in the Tadeu Cvintal Ophthalmology Institute, from January 2004 to January 2005. METHODS: Retrospective study […]
