OBJECTIVE This study is to compare the efficacy of three different cataract surgeries in eyes with angle closure glaucoma (ACG) with concomitant cataract. METHODS A retrospective comparative analysis of 106 ACG patients (112 eyes) with concomitant cataract was conducted between February, 2012 and February, 2014. Clinical outcomes of ACG patients with concomitant cataract underwent phacoemulsi...

PURPOSE To investigate the fluctuations of directly measured intraocular pressure (IOP) and induced diastolic ocular perfusion pressure (DOPP) during three simulated steps of phacoemulsification in vivo. METHODS Twenty-five eyes of 25 patients who underwent phacoemulsification were evaluated. A pressure transducer was inserted into the anterior chamber to measure IOP directly. The cortical cl...

BACKGROUND Cataract surgery remains a commonly performed elective surgical procedure in the aging and the elderly. The purpose of this study was to utilize time series methodology to determine the temporal and seasonal variations and the strength of the seasonality in age-related (senile) cataract hospitalizations and phacoemulsification surgeries. METHODS A retrospective, cross-sectional tim...

BACKGROUND: Postoperative fibrinoid syndrome (PFS) is an early complication of phacoemulsification, manifested by fibrin deposition on the iris and intraocular lens surface, which leads to visual acuity decrease.
 AIM: To assess rate treatment efficacy (by YAG laser, enzymatic, medicalmentous) in PFS after phacoemulsification.
 MATERIALS AND METHODS: Retrospective analysis 56,019 cata...

This paper presents the development of a low-cost cataract surgery simulator for trainees to practise phacoemulsification procedures with computer-generated models in virtual environments. It focuses on the training of cornea incision, capsulorrhexis and phaco-sculpting, which are simulated interactively with computationally efficient algorithms developed for tissue deformation, surface cutting...

PURPOSE To evaluate the clinical outcomes of new phacoemulsification technology. SETTING Oregon Eye Institute, Eugene, Oregon, USA. METHODS After optimization of surgical parameters, patients were randomly assigned to cataract extraction with 1 of 4 phacoemulsification machines using new technology available within the past 1 to 2 years. Outcomes were compared with previously published resu...

background : phacoemulsification is one of the best surgical treatments for the cataract. secondary to the technicaladvances in estimating the intraocular lens (iol) power, the refractive errors, one of the most important surgical complications after surgery, is now reduced. currently, two methods of biometry are used to calculate the iol power, ultrasound biometry and optical biometry. both me...
