OBJECTIVE: Evaluation of patients undergoing sequential sessions of RV and report its benefit in improving visual acuity (VA). METHODS: Cross sectional study with a sample of 10 patients who underwent sequential sessions of the RV. Patients were treated at a rate of 2-3 sessions per week for a period of 2 to 3 months and was completed after 20 to 40 sessions. The main inclusion criteria were post cataract surgery (without complications) and multifocal IOL until +3.00 D, astigmatism <-1.00 […]

PURPOSE: Development and validation of quality of life questionnaire in pseudophakic patients in Portuguese. METHODS: The modified Cataract TyPESpecification questionnaire was specifically developed to assess quality of life after cataract surgery, functional status evaluated with 10 items and contains 18 questions. All questions were applied by a single examiner, with the goal of graduating visual satisfaction from 0 to 10 (0 means very dissatisfied, 5 neutral, 10 very satisfied).This prospective comparative study included 142 eyes of 71 patients in Sao […]

To correct a high hyperopia and irregular astigmatism secondary to multiples refractive surgeries in a 45 years old female, radial incisions suture and intraocular (IOL) Acrysof Toric lens was performed. To correct the residual refractional error a pseudophakic toric supplementary IOL was implanted over the primary one.The initial visual acuity (VA) was LogMAR 0,9 and the final VA was LogMAR 0,3. The implant of IOL supplementary over a primary toric IOL appears to be a good option, increasing the visual […]

OBJECTIVE: Compare PRK and Epi-LASIK techniques regarding postoperative visual recovery and symptoms. METHODS: Interventional case series study including 38 eyes of 19 patients with myopia up to 5DE and astigmatism up to 1DC. Study included patients with similar refractive errors to be submitted to PRK in one eye and Epi-LASIK in the fellow eye at the same time. Follow-up was 1 year and included refractive error analysis and postoperative discomfort. RESULTS: During the first 12 hours after surgery, 79% (P=0,0003) […]

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 […]

OBJECTIVE: Evaluate the knowledge of medical students from Universidade Estadual de Londrina (UEL), about refractive surgery, as well as analyzing the percentage of students that presents refractive errors, their correction methods and their interest (or not) in the surgical procedure. METHODS: We conducted a survey using self-evaluation questionnaire (previously tested) among 154 medical students from first to fourth year, between september and november 2011. RESULTS: It was reported that 70.8% of students had some type of refractive error, and myopia […]

OBJECTIVE: We intend to evaluate the prevalence of visual disorders among 8 to 10-year-old students from a public school in Pouso Alegre, state of Minas Gerais, as well as verify the possible legitimacy of the correlation between a poor school performance and some kind of visual deficit. METHODS: We conducted a transversal and quantitative study whose target were the students enrolled in the elementary course (2nd to 4th grade) of Pio XII Municipal School in the academic year of 2009. […]

OBJECTIVE: To evaluate the correlation of flow and stopping time intraoperative loss of attachment factors as hypertension or hipocorreções of refractive errors after Lasik. METHODS: The age ranged between 19 and 61 years (mean= 31.27 ± 9.99). The minimum follow-up period was 90 days. Individuals with: corneal topography preoperative maximum keratometry greater than 46.5D or presence of irregularities, corneal curvature postoperative simulated smaller 36.0D, pupils more 6mm; corneal thickness smaller 500 µm; Myopia more -8.0, hyperopia more +5.0DE and astigmatism […]
