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 […]

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 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, […]

PURPOSE: To analyze the results of combined cataract and glaucoma surgery and to present the technique with scleral peri-limbic suture. METHODS: Retrospective study with review of the data about intraocular pressure, visual acuity, antihypertensive medication before and after surgery and description of the combined surgery technique, with follow up of six months. We selected 10 patients with glaucoma and cataract (15 eyes) followed up from January 2005 to June 2007 from Santa Casa Olhos de Montes Claros (MG). The glaucoma […]

PURPOSE: To compare the costs of cataract surgery for a public hospital, the government and the society between the techniques of phacoemulsification (PHACO) and extracapsular cataract extraction (EECP). METHODS: A review based on several clinical studies between 2002 and 2010 at the Ambulatorial Surgical Center of the University of São Paulo. RESULTS: The estimated expenses associated with medical supplies used for surgery were R$ 468.92 and R$ 259.96 in the PHACO and EECP groups respectivelly. The hospital expenditures in the […]
