Objetivo: Relatar a prevalência e analisar os padrões de astigmatismo corneano em candidatos à cirurgia de catarata. Métodos: Os pesquisadores examinaram 2136 olhos de 1204 pacientes a cirurgia de catarata de 1 de janeiro a 31 de dezembro de 2016. Todos os candidatos foram avaliados com interferometria de coerência parcial (IOLMaster). Os resultados foram analisados estatisticamente em relação às variáveis qualitativa e quantitativa. Resultados: A média de idade dos pacientes foi de 71,9 anos, com predomínio do sexo feminino. A […]

Objective: To evaluate the efficacy of cataract surgery performed in the city in 2017, aiming to increase the production of cataract surgeries and reduce the prevalence of cataract in the population. Methods: This is an observational, descriptive, cross-sectional and retrospective study based on the data analysis of the cataract mutirão developed in Itajubá, in the year 2017, through information from records obtained from the Outpatient Information System (SIA / SUS) and the Hospital Information System (SIH / SUS), concomitant with […]

Purpose: To report the prevalence and analyse corneal astigmatism patterns in cataract surgery candidates. Methods: Researchers examined 2136 eyes from 1204 patients for cataract surgery from 1 January to 31 December 2016. All the candidates were evaluated with partial coherence interferometry (IOLMaster). The results were analysed statistically in relation to qualitative and quantitative variables. Results: The mean age of the patients was 71.9 years with a female predominance. Mean corneal astigmatism was 1.0 dioptre (D). Against the rule (ATR) astigmatism […]

We report a case of residual astigmatism after cataract surgery with toric intraocular lens (IOL) implantation (Acrysof Toric, Alcon, Frot Worth TX). Residual refraction (+1,25 -2,50 x 105º) and IOL positioning were correlated with total ray-tracing wavefront aberrometry integrated with anterior corneal surface Placido-based topography to calculate internal aberrations (iTrace, Tracey Technologies, Houston TX). The ideal IOL axis to minimize residual refraction was calculated with Berdahl & Hardten (astigmatismfix.com). IOL rotation to the indicated axis was successfully performed 5 months […]

Objetivo: Comparar a previsibilidade dos resultados refracionais e da biometria em pacientes submetidos à cirurgia de catarata por facoemulsificação com e sem trabeculectomia (Trec) associada. Métodos: Pacientes com catarata submetidos à cirurgia de facoemulsificação isolada (grupo controle) ou associada a Trec (catarata + glaucoma, grupo estudo) foram consecutivamente selecionados. Todas as cirurgias foram feitas seguindo protocolo padrão. Para inclusão, era necessário apresentar biometria calculada pelo biômetro IOL Master (Carl Zeiss, Meditec, Inc), refração e pressão intraocular (Pio) pré e pós-operatórios. […]

Objective: The main purpose of this article is to compare the predictability of biometric results and final refractive outcomes expected in patients undergoing cataract surgery through phacoemulsification with and without associated trabeculectomy. Methods: Cataract patients who have undergone phacoemulsification surgery alone (control group) or associated with trabeculectomy (study group) screened. All surgeries were performed following standard protocol. For enrollment, biometrics calculated by IOL Master (Carl Zeiss Meditec, Inc.) biometry, refraction and intraocular pressure (IOP) before and after surgery were required. […]

Spontaneous rupture of the anterior lens capsule, evolving with anterior dislocation of the lens nucleus is a rare complication of hypermature cataract. We report a case of a female patient, 79 years old, who presented with spontaneous rupture of the anterior lens capsule with anterior dislocation of the nucleus in the right eye with no history of ocular trauma. The diagnosis was confirmed by the visualization of the tabs of the anterior capsule, especially when the nucleus was removed. We […]

Objective: To test the efficacy of Acetylcholine chloride use in obtaining intraoperative miosis on phacoemulsification cataract surgery. Methods: Patients with cataract diagnosis and elected for surgical phacoemulsification procedure were selected. All patients underwent conventional phacoemulsification procedure performed by a single surgeon and all patients had 0.2 ml of Acetylcholine chloride 1% irrigated in the anterior chamber at the end of the surgery. The pupillary diameter was measured immediately before the beginning of surgery, immediately before and two minutes after the […]
