Objective: To compare refractive and vectorial outcomes of limbal relaxing incisions (LRI) versus toric intraocular lenses (IOL) in the treatment of preexisting corneal astigmatism at the time of phacoemulsification. Methods: This longitudinal observational case series assessed 62 eyes of 31 consecutive cataract patients with preoperative corneal astigmatism between 0.75 and 2.50 diopters in both eyes. Patients were randomly assorted in two groups: one assigned to receive AcrySof Toric™ IOL in both eyes, and another one assigned to have AcrySof Natural™ […]

OBJECTIVE: Comparison of the visual performance between patients with Tecnis® MF ZM900, Acrysof® Restor® SN60D3, Acrysof® SN60AT and Acrysof® SN60WF intraocular lenses. METHODS: This prospective comparative study included 142 eyes of 71 patients in Sao Paulo University. The ophthalmologic evaluation performed included near, intermediate and distance corrected and uncorrected visual acuity, contrast sensitivity measurement and wavefront analysis. The minimum follow-up was 6 months. RESULTS: The mean age of patients was 60.7±6.6years in the Tecnis®MF, 63.1±4.4 years in-group Restor® 63.7±4.2 years […]

PURPOSE: To correlate straylight levels, lens scattering, lens opacity and intraocular aberrometry in patients with nuclear cataract. METHODS: This is a prospective study. Thirty consecutive patients (30 eyes) were including. Ocular Straylight was evaluated using the C-Quant. Lens scattering was evaluated using Scheimpflug anterior segment tomography, using the new software PNS. Dilated slip lamp evaluation was performed and lens opacity was classified according to LOCS III scale. Total wavefront was measured by ray tracing (iTrace); intraocular aberrations were calculated by the […]

We present a case of double ring capsulorhexis in a 81 year-old female patient. Surgical specimen was submitted to histopathologic study resulting in typical double ring capsulorhexis findings. We discuss the questioned relation to true capsular exfoliation. We call attention to the fact that it is possible to obtain a good surgical result even when the double ring is not complete – as the case presented – , since both capsular flaps are fused in a continuous form.

OBJECTIVE: To evaluate the anatomic and the visual results of patients with traumatic cataract who sought care in Hospital de Olhos do Paraná (HOP), that were subjected  to surgical treatment in this service. To describe their epidemiological and clinical aspects, and to analyze the post operative functional results. METHODS: There were included in the study all patients subjected to a surgical treatment and the following characteristics were analyzed: sex, age, pre and postoperative visual acuity, mechanism of trauma, associated ocular […]

This paper describes the intraoperative refraction for intraocular lens (IOL) power calculation. Report a case of a 67 year-old male patient reporting a progressive loss of visual acuity in the left eye (OS). Examination revealed best corrected visual acuity (BCVA) of 20/60 (-21,50 -4,00 X 170) related to adherence of silicone oil to the IOL optic. IOL exchange was proposed, however biometry was variable and doubtful. Intraoperative refraction confirmed the IOL power and the patient underwent uneventful IOL explantation and […]

Fuchs’ heterochromic iridocyclits or Fuchs’ Syndrome is a kind of uveitides relatively uncommon. Affect equally both genders, between 20-45 years old, in the classic features include a chronic unilateral nongranulomatous inflammation in anterior uvea, insidious onset, low-grade in activity, and unresponsive to corticosteroid therapy. Usually has a good prognosis, except for the development of cataract and glaucoma, pathologies associated with syndrome. In this case, there are a male pacient, 68 years, with glaucoma as the first manifestation of the Fuchs’Syndrome.

PURPOSE: To evaluate the complication’s rate of cataract surgery performed by ophthalmology residents (second and third-year) and experienced surgeons at a public teaching hospital. METHODS: A retrospective chart review of all patients who had cataract surgery between March (begin of the technique practice) and November (end of the technique practice) was conducted. RESULTS: In 481 cataracts surgeries, 194 (40%) was performed by third-year residents, 165 (34%) by second-year residents and 116 (26%) by experienced surgeons. The most frequent complication in […]
