Purpose: To measure and compare size and shape parameters of femtosecond laser capsulotomy with manually continuous curvilinear digital guided capsulorhexis (CCC) and their refractive outcomes. Methods: Laser capsulotomies in 40 eyes of 40 patients were performed using LenSx femtosecond laser device (Alcon, Forthworth, US) and its results were compared with the CCC digital guided carried out in 40 eyes of 40 patients using the Callisto Eye digital image system (Zeiss, Germany). Capsulorhexis circularity, shape and capsule overlap were measured using […]

Objetivo: Comparar os resultados refracionais e de análise vetorial, das incisões relaxantes limbares (IRL) versus lentes intraoculares (LIO) tóricas no tratamento do astigmatismo corneano pré-existente por ocasião da facoemulsificação. Métodos: Estudo observacional longitudinal (série de casos) no qual foram avaliados 62 olhos de 31 pacientes consecutivos de catarata com astigmatismo corneano pré-operatório entre 0,75 e 2,50 dioptrias para ambos os olhos. Os pacientes foram aleatoriamente distribuídos entre 2 grupos: um submetido a implante de LIO AcrySof Toric™ em ambos os […]

OBJETIVO: Estabelecer modelos de regressão linear entre os índices propostos por Alpins com os vetores astigmáticos de Thibos, avaliando a validade e a força dessas correlações. MÉTODOS: Série de casos na qual foram avaliados prospectivamente 62 olhos de 31 pacientes de catarata com astigmatismo corneano pré-operatório entre 0,75 e 2,50 dioptrias para ambos os olhos. Os pacientes foram aleatoriamente distribuídos entre 2 grupos: um submetido a implante de lente intraocular (LIO) AcrySof ToricTM em ambos os olhos e outro grupo, […]

PURPOSE: To determine linear regression models between Alpins descriptive indices and Thibos astigmatic power vectors (APV), assessing the validity and strength of such correlations. METHODS: This case series prospectively 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 among two phacoemulsification groups: one assigned to receive AcrySof®Toric intraocular lens (IOL) in both eyes and another assigned to have AcrySof Natural IOL associated with limbal relaxing […]

PURPOSE: To evaluate the outcome and safety of phacoemulsification performed under topical anesthesiain cases with several complexities. METHODS: Cases performed under topical anesthesia from january 2009 to april 2011 were analyzed. Variables analyzed included patients age, sex, race, systemic diseases, eyes comorbidities, type of cataract, visual acuity before and after the surgery, complications, number of conversions to peribulbar anesthesia and IOL power. Patients with uncompleted data were excluded from analysis. RESULTS: A total of 111 eyes were analyzed; only cases […]

PURPOSE: To evaluate long-term results of the secondary piggyback technique used for the correction of undesired ametropia after phacoemulsification. METHODS: Retrospective study comprising of 20 eyes (19 patients). The IOL used was a single-piece PMMA with an overall length of 12.5mm, a 5x6mm oval thin-edged optic with a 10-degree haptic angulation. The same technique was used in all cases, consisting of a scleral-corneal tunnel with a 5mm opening, through which the secondary intraocular lens was implanted into the ciliary sulcus. […]

O descolamento da membrana de Descemet pode ser uma complicação grave após a cirurgia de catarata, resultando em edema de córnea e redução da acuidade visual. Este relato descreve um caso raro de descolamento da membrana de Descemet seis meses após cirurgia de catarata com facoemulsificação sem intercorrências, documentado com tomografia de coerência óptica do segmento anterior (OCT; RTVue, Optovue). Foram realizadas descemetopexia pneumática e sutura corneana, com resolução do descolamento e recuperação visual. Este relato procura alertar os médicos […]

The detachment of Descemet’s membrane can be a serious complication following cataract surgery, leading to severe corneal edema and reduced visual acuity. This report describes an unusual case of Descemet’s membrane detachment 6 months after successful phacoemulsification, documented by anterior segment optic coherence tomography (OCT; RTVue, Optovue). The eye was treated successfully with pneumatic descemetopexy and transcorneal suturing, with reattachment of Descemet’s membrane. This report should alert physicians that delayed corneal edema can be related to late-onset Descemet’s membrane detachment, […]
