Objective: To evaluate the introduction of the femtosecond laser (FSL) to perform the key steps of the traditional cataract surgery process and the operational difficulties and safety of this new technology during routine use in an operating room in Brazil. Methods A retrospective study was conducted using the first cases operated on at a single center using the laser platform LenSx/Alcon with a soft contact lens patient interface.All patients underwent a detailed preoperative assessment.The anterior capsulotomy, nuclear fragmentation, and corneal […]

Purpose: To evaluate the changes of corneal biomechanical after femtosecond laser – assisted cataract and to compare the parameters derived by Corvis ST between standard phacoemulsification and femtosecond laser – assisted in cataract surgery Methods: This is a prospective study. 151 eyes of 127 patients were under went cataract surgery. 75 eyes of 65 patients were with femtosecond laser–assisted (FS)(Alcon Len Sx, Aliso Viejo,USA) and 76 eyes of 62 patients with standard phacoemulsification (SP) (Alcon Infinit, Fort Worth, USA). Lens […]

Objetivo: Avaliar a introdução do laser de femtossegundo (FSL) para realizar etapas fundamentais da cirurgia de catarata tradicional e as dificuldades e segurança desta nova tecnologia na rotina de um centro cirúrgico no Brasil. Métodos: Um estudo retrospectivo foi realizado com os primeiros casos operados em um único centro usando a plataforma de laser LenSx/Alcon, sendo utilizado lentes de contato gelatinosa na interface do paciente. Todos os pacientes foram submetidos a uma avaliação pré-operatória detalhada. Capsulotomia anterior, fragmentação nuclear e […]

Objective Compare visual acuity (VA) of patients after cataract surgery with and without intraoperative complications regarding possible factors that contributed to the outcome on postoperative follow-up. Methods Longitudinal, retrospective study that evaluated 179 medical records of patients who underwent cataract surgery under the technique Phacoemulsification (PHACO) in the Suel Abujamra Institute from february to july 2013. Patients were divided into two groups concerning presence or absence of intraoperative complications. Data were analyzed using t-test methods for two samples or (ANOVA) […]

Objetivo: Avaliar os resultados pós-operatórios da utilização da LIO tórica durante a facoemulsificação. Métodos: Estudo retrospectivo tipo coorte de 95 olhos de 67 pacientes, selecionados através de censo. Foram analisados pacientes com catarata, submetidos à facoemulsificação, com colocação da LIO tórica Acrysof®, no período de janeiro de 2010 a dezembro de 2012. No entanto, foram excluídos os que realizaram outro tipo de cirurgia ou tiveram outro tipo de lente para correção da catarata e/ou prontuários incompletos. Considerou-se como sucesso o […]

Purpose: To evaluate the postoperative results when using the toric IOL during phacoemulsification. Methods: Retrospective cohort based study on the 95 eyes of 67 patients, selected by a census. Analyzed patients with cataracts who had undergone phacoemulsification placement with AcrySof® toric IOL from january 2010 to december 2012. For analysis purposes, it was considered successful when the residual astigmatism was d”0.75 diopters. The Wilcoxon test for related samples was used to compare non-parametric samples, while the Student T test was […]

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 […]
