AIM: To conduct a systematic review and quantitative Meta-analysis of the efficacy and safety of combined surgery for the eyes with coexisting cataract and open angle glaucoma. METHODS: We performed a systematic search of the related literature in the Cochrane Library, PubMed, EMBASE, Web of Science databases, CNKI, CBM and Wan Fang databases, with no limitations on language or publication date. The primary efficacy estimate was identified by weighted mean difference of the percentage of intraocular pressure reduction (IOPR%) from baseline to end-point, the percentage of number of glaucoma medications reduction from pre- to post-operation, and the secondary efficacy evaluations were performed by odds ratio (OR) and 95% confidence interval (CI) for complete and qualified success rate...

PURPOSE: To determine if phacoemulsification with intraocular lens implantation has a greater impact on the corneal endothelium of type 2 diabetic patients as compared to nondiabetics. MATERIALS AND METHODS: This study compared the endothelial status in 60 diabetics with good glycemic control and 60 nondiabetics before and after uneventful phacoemulsification. Central corneal endothelial cell density, percentage hexagonality and percentage coefficient of variation (%CV) were measured using a specular microscope...

PURPOSE: To compare the efficacy and safety of endoscopic cyclophotocoagulation (ECP) versus trabeculectomy with mitomycin C (trab) in combination with cataract surgery. MATERIALS AND METHODS: We evaluated the 6-month results of patients undergoing phacoemulsification (phaco) with either ECP or trab. The primary outcome was mean intraocular pressure (IOP) at 6 months; secondary outcomes were change in glaucoma medications, visual acuity, intraocular inflammation, and postoperative complications...

Rheology can be defined as the study of materials flow behaviour under applied deformation forces (stresses). Inside the eye during cataract surgery, transient or reversible deformation (elasticity) and permanent or irreversible deformation (flow) can both apply. Although the fluidics of modern phaco machines is an important part of this talk, there are a number of issues relating to flow and fluids in the eye during cataract surgery, which are unrelated to the machine, which can hinder or help the operating surgeon in removing a cataract...

INTRODUCTION: We present a case of persistent aqueous misdirection post Ahmed glaucoma valve despite undergoing an anterior vitrectomy with hyaloido-zonulectomy, and iridectomy. CASE REPORT: A 73 year old female 4 months post phaco-trabeculectomy was referred with persistent high IOP. Post-operatively, she developed aqueous misdirection with a flat anterior chamber (AC) but with an IOP of 15▒mm Hg. On presentation her AC was shallow with peripheral iris-cornea touch and IOP was 39▒mm Hg...

One of the challenging situations for a cataract surgeon is phacoemulsification in the shallow anterior chamber like cases of phacomorphic glaucoma. Some of the main concerns of operating in a narrow space include endothelial decompensation, descemet's detachment, and posterior capsular rents. High vitreous pressure predisposes to posterior capsular rents owing to a reduced concavity of the posterior capsule and increasing the proximity of phaco-tip to the posterior capsule. We describe a technique of limited vitrectomy in such cases...

PURPOSE: To describe the intraoperative complications and the learning curve of microincision cataract surgery assisted by femtosecond laser (FLACS) with bimanual technique performed by an experienced surgeon. METHODS: It is a prospective, observational, comparative case series. A total of 120 eyes which underwent bimanual FLACS by the same experienced surgeon during his first experience were included in the study; we considered the first 60 cases as Group A and the second 60 cases as Group B...

The Argentinean Flag Sign is a complication that occurs during capsulorhexis construction, in which the capsulorhexis extends to the periphery due to lens intumescence. Phaco capsulotomy is a technique in which the phacoemulsification tip is used to simultaneously create the initial tear in the anterior capsule and remove a portion of the intumescent lens, thereby debulking and relieving pressure from the lens and capsule, and preventing the Argentinean Flag Sign. A detailed description of the phaco capsulotomy technique is provided, including applications and potential complications...

PURPOSE: To compare two different fragmentation patterns in femtosecond laser-assisted cataract surgery (FLACS) in terms of phaco values, postoperative endothelial cell count (ECC) and corneal thickness (CT). METHODS: This non-randomized, retrospective cross-sectional study included patients with senile cataract of grade 3 who underwent FLACS using the LenSx laser system. In Group 1 (32 eyes), lens fragmentation was created as a cross pattern. In Group 2 (35 eyes), lens fragmentation was created as a hybrid pattern...

PURPOSE: Phacoemulsification is the surgical procedure of choice for cataract, providing excellent visual and safety outcomes. Femtosecond laser-assisted cataract surgery (FLACS) is an addition to the surgical armamentarium. The study aims to compare the outcomes of FLACS using LenSx™ (Alcon Inc., USA) to standard 2.2 mm clear corneal phacoemulsification. Prospective case-control, comparative, interventional study was conducted in a tertiary care center. METHODS: In each group, 55 eyes of 55 patients underwent cataract surgery using either FLACS or conventional phacoemulsification (control group)...

BACKGROUND: Trabectome surgery combined with phacoemulsification is effective in lowering (intraocular pressure) IOP in pseudoexfoliation glaucoma. Trabectome surgery usually aims to remove two to four clock hours of the trabecular meshwork. When adding trabecular aspiration, the remaining meshwork can be treated as well, and therefore 360 degrees of the meshwork can be reached. This study was conducted to investigate the additional benefits and risks of adding trabecular aspiration to the combination of phacoemulsification and trabectome as a triple procedure...
