PURPOSE: The aim of this study is to compare visual acuity, contrast sensitivity, reading speed and quality of life of postoperative pseudophakic patients with unilateral or bilateral ReZoom multifocal intraocular lenses. METHODS: Comparative, prospective, not randomized study including 38 eyes of 24 patients were divided into a group with bilateral implantation (14 patients) and another with unilateral implantation (10 patients). The ophthalmological examination included visual acuity preoperative close, intermediate and far away, best corrected visual acuity, corneal topography, contrast sensitivity, […]

OBJECTIVE: To verify if the total ocular aberrometry (wavefront analysis) facilitates manifest refraction and improvement in best spectacle distance corrected visual acuity (BSCDVA) with sphero-cylindrical lenses, in keratoconus cases with some degree of contact lenses intolerance. METHODS: Retrospective chart review of 46 patients (89 eyes) referred with keratoconus and contact lenses intolerance was performed. Ocular aberrometry with ray tracing was followed by manifest refraction. BSCDVA (logMAR) with the previous correction was compared with the one obtained based on the wavefront […]

PURPOSE: To evaluate distance, intermediate, and near vision after aspheric multifocal diffractive AcrySof® ReSTOR® SN6AD1 intraocular lens (IOL) implantation. METHODS: Prospective study of 50 patients with cataract that had phacoemulsification and AcrySof® ReSTOR® IOL implantation. Uncorrected distance vision acuity (UDVA), corrected distance visual acuity (CDVA), distance-corrected near visual acuity (DCNVA), and distance-corrected intermediate visual acuity (DCIVA) were measured postoperatively. A patient-satisfaction and visual phenomena questionnaire was administered at the end of the study. RESULTS: Three months postoperatively, the mean acuities […]

PURPOSE: the aim of the present study is to compare the intraocular pressure (IOP) and visual acuity (VA) after combined surgery: phacoemulsification with non penetrating deep sclerectomy and phacoemulsification with trabeculectomy. METHODS: this is an observacional and retrospective study by chart review. We selected 148 eyes from 127 patients from Tadeu Cvintal Ophthalmolgy Institute during January 1998 thru January 2007. All patients had primary angle glaucoma and cataract. Seventy seven patients were female, 49 (59%) had phacoemulsification with non penetrating […]

PURPOSE: The aim of this study was to evaluate the role of 25-gauge transconjuntival sutureless vitrectomy (TSV) in patients with persistent vitreous floaters who underwent multifocal intraocular lens (IOL) implantation. METHODS: Fourteen eyes of 11 patients with multifocal IOL implant associated with vitreous opacities that underwent 25-gauge vitrectomy were prospectively analyzed. Information collected included near (UCNVA) and distance uncorrected visual acuity (UCDVA), best corrected distance visual acuity (BCDVA), and the spherical equivalent (SE) before and 3 months after vitrectomy. Patients […]

OBJECTIVE: To evaluate the influence of visual acuity in instrumental activities of daily living in elderly patients in follow-up period. METHODS: through own instruments, sixty-four elderly men and women were interviewed in clinical segment at an academic hospital of Campinas/SP. They were then divided into two groups in accordance to the values that were obtained through the measure of the VA: the first group consisted of elderly people with normal vision or close to the normal, and the second group […]

OBJECTIVES: To determine amblyogenic factors and amblyopia prevalence in a Health Family assisted community área of Lapa (RJ); and to estimate in the same area the sensiblity and specificity among visual acuity methods ( ETDRS versus LEA optotypes) in pre-school children. METHODS: Cross section study of 93 children from three to six years old. All the children were submitted to complete ophthalmological evaluation which included: anamnesis, ectoscopy, double blind visual acuity measurements with LEA and ETDRS optotypes, red reflex, Titmus […]

PURPOSE: To improve health services it is necessary to know the demand profile. This study was carried out with the objectives of: to identify the main reasons to seek an ophthalmologic primary care service; and to analyze the frequency of the principal diagnoses, according to gender and age groups, as well as the causes of referring patients. METHODS: Retrospective and descriptive study of 1,010 assisted patients during a period of 6 months. Parameters: age and sex of the patient, the […]
