PURPOSE To evaluate wavefront performance and modulation transfer function (MTF) in the human eye after the implantation of diffractive or refractive multifocal intraocular lenses (IOLs). MATERIALS AND METHODS This was a prospective, interventional, comparative, nonrandomized clinical study. Uncorrected distance and near visual acuity, and wavefront(More)
PURPOSE To evaluate the governmental costs of patients undergoing phacoemulsification and extracapsular cataract extraction at a public hospital in a developing country. METHODS A prospective study was conduced with 205 patients. The subjects were randomized for cataract surgery using either phacoemulsification or extracapsular cataract extraction(More)
PURPOSE To compare the intraoperative safety of two techniques of capsulorhexis for intumescent white cataracts: traditional one-stage continuous curvilinear capsulorhexis and two-stage continuous curvilinear capsulorhexis. METHODS This prospective comparative randomized study included two groups: the 1-CCC group (11 patients) received traditional(More)
This paper focuses on reviewing the roles of optical coherence tomography (OCT) on corneal surface laser ablation procedures. OCT is an optical imaging modality that uses low-coherence interferometry to provide noninvasive cross-sectional imaging of tissue microstructure in vivo. There are two types of OCTs, each with transverse and axial spatial(More)
OBJECTIVE To evaluate the frequency and characteristics of ocular manifestations in outpatients with systemic sclerosis. METHODS In this cross-sectional study, 45 patients with systemic sclerosis were enrolled. Data regarding demographics, disease duration and subtype, age at diagnosis, nailfold capillaroscopic pattern and autoantibody profile were(More)
PURPOSE To evaluate intraindividual visual acuity, wavefront errors and modulation transfer functions in patients implanted with two diffractive multifocal intraocular lenses. METHODS This prospective study examined 40 eyes of 20 cataract patients who underwent phacoemulsification and implantation of a spherical multifocal ReSTOR intraocular lens in one(More)
Researchers in the field of clinical epidemiology study the distribution and the determinants of health problems to gain insight into how to address public health programs. Specifically, health professionals focused on the development and monitoring of public health projects should base their actions on clinical efficacy and safety data. Until the(More)
The aim of this study was to identify inequalities in corneal donation and transplantation among the regions of Brazil. A transversal and retrospective study was specifically conducted using data from the Brazilian Transplant Registry collected by the Brazilian Association of Organ Transplantation between January 2002 and December 2014. The collected data(More)
OBJECTIVE This study sought to describe and analyze ocular findings associated with nonocular surgery in patients who underwent general anesthesia. METHODS The authors retrospectively collected a series of 39,431 surgeries using standardized data forms. RESULTS Ocular findings were reported in 9 cases (2.3:10,000), which involved patients with a mean(More)
OBJECTIVES The aim of this study was to report the type and frequency of ocular manifestations in Brazilian psoriatic arthritis patients. METHODS We conducted a cross-sectional study in a Brazilian tertiary hospital. The test group included 40 patients who had psoriatic arthritis according to the Classification Criteria for Psoriatic Arthritis. A control(More)
