AIM: An analysis of late in-the-bag dislocation of intraocular lenses (IOL), in uveitic eyes. SETTING: Referral uveitis clinic. DESIGN: Retrospective case series. MATERIALS AND METHODS: All case records of eyes with chronic uveitis that had phacoemulsification with IOL implantation, at a referral uveitis clinic between February 1997 and January 2015 were retrieved and analyzed. Only those eyes with no documented intraoperative complication and no predisposing risks to IOL dislocation, such as pseudoexfoliation, high myopia, trauma, and prior VR surgery were included in this study...

PURPOSE: The aim of this study is to compare the length of time from uneventful cataract surgery using one of two common posterior chamber intraocular lenses (IOLs) (hydrophilic versus hydrophobic acrylic) to laser capsulotomy. MATERIALS AND METHODS: Retrospective analysis of all patients who underwent neodymium: yttrium-aluminum-garnet laser capsulotomy between 2011 and 2014 following uneventful phacoemulsification surgery at a tertiary university-affiliated medical center...

Intraoperative optical coherence tomography (iOCT) is a noninvasive imaging modality that provides a real-time dynamic feedback of the various surgical steps. Comprehensive literature search was performed in MEDLINE using "intraoperative optical coherence tomography" and "iOCT" as keywords. The use of iOCT as an aid to decision-making has been successfully reported in cases undergoing keratoplasty, implantable Collamer lens (ICL) implantation as well as cataract surgery. iOCT helps to assess the graft-host relationship in penetrating keratoplasty...

PURPOSE: We decided to evaluate the decrease in intraocular pressure six months after cataract surgery. MATERIALS AND METHODS: We evaluated patients' IOP using an applanation tonometer. The patients then underwent cataract surgery. Six months after cataract surgery, we reevaluated the IOP by the same method, and we determined the post-operative change. RESULTS: Among the 147 operated eyes, 123 eyes or 83.67% exhibited a decrease in IOP. The mean preoperative IOP for the operative eye was 15...

PURPOSE: For patients with comorbid cataract and primary open-angle glaucoma (POAG), guidance is lacking as to whether cataract extraction and traditional filtering surgery should be performed as a staged or combined procedure. Achieving this guidance requires an evidence-based understanding of the effects of phacoemulsification alone on intraocular pressure (IOP) in patients with POAG. For this reason, a systematic review and meta-analysis was undertaken to synthesize evidence quantifying the effect of phacoemulsification on IOP and the required number of topical glaucoma medications in patients with cataract and POAG...

BACKGROUND: To stratify the outcomes of phacoemulsification combined with trabectome surgery using a new glaucoma severity index. METHODS: This is a retrospective, observational cohort study that included open angle glaucoma patients with visually significant cataract that had phacoemulsification combined with trabectome surgery. Exclusion criteria were follow-up less than 12 months, any other surgeries or diagnosis of neovascular or active uveitic glaucoma. Patients were stratified into four groups according to the Glaucoma Index (GI) that incorporated preoperative intraocular pressure (IOP), number of medications and visual field status...

PURPOSE: To compare the clinical performance and safety of 2 ophthalmic viscosurgical devices (OVDs)-Twinvisc (OVD 1) and Duovisc (OVD 2)-in cataract surgery. SETTING: European multicenter study. DESIGN: Prospective randomized controlled study. METHODS: Patients with cataract had phacoemulsification and intraocular lens implantation in 1 eye. They were randomly assigned to receive OVD 1 or OVD 2. Preoperative and postoperative examinations over 3 months included mean intraocular pressure (IOP), incidence of IOP peaks (≥30 mm Hg and ≥24 mm Hg), endothelial cell count (ECC), corneal thickness, and intraocular inflammation...

We describe a technique for performing safe phacoemulsification of a Morgagnian cataract using the intraocular lens (IOL) scaffold. An IOL scaffold has been used in cases in which posterior capsule rupture has occurred, leaving nonemulsified nuclear pieces. The scaffold provides a barrier that prevents the nuclear fragments from falling posteriorly into the vitreous cavity. Our technique uses the IOL as a scaffold to prevent the vulnerable posterior capsule from rupturing during nuclear emulsification in Morgagnian cataract...

OBJECTIVE: To know the outcomes of cystoid macular oedema after phacoemulsification in patients with and without type 2 diabetes mellitus using optical coherence tomography. METHODS: This non-concurrent, clinical, prospective study was carried out at Al-Ibrahim Eye Hospital, Karachi, from January to August 2015. After phacoemulsification with injectable posterior chamber intraocular lens implantation, eyes of patients were analysed.

PURPOSE: Rotating wire brushes are used, e.g., for rust removal. Detaching fragments can cause severe eye injuries. The purpose of this study was to investigate mechanism, severity, clinical outcome, validity of Ocular Trauma Score (OTS) and to assess the likelihood of final visual acuity. METHODS: Twenty patients with traumatic ocular injuries by rotating wire brushes were included. Location and type of injury, grade of injury according to OTS, surgical procedure, and development of visual acuity were evaluated...

AIMS: To develop financial models which offset additional costs associated with femtosecond laser (FL)-assisted cataract surgery (FLACS) against improvements in productivity and to determine important factors relating to its implementation into the National Health Service (NHS). METHODS: FL platforms are expensive, in initial purchase and running costs. The additional costs associated with FL technology might be offset by an increase in surgical efficiency. Using a 'hub and spoke' model to provide high-volume cataract surgery, we designed a financial model, comparing FLACS against conventional phacoemulsification surgery (CPS)...

Opacification of a hydrophilic acrylic intraocular (IOL) lens is a rare phenomenon. We herein report a case of a 57-year man complaining of decreased vision at left eye for the last 4 months. He had undergone phacoemulsification with IOL implantation 2 years back. IOL opacification was observed through slit-lamp. IOL exchange was carried out. The exchanged IOL and a new lens of the same model were sent to laboratory for pathologic analysis. Confocal microscopy showed uniformly distributed granules from the surface to 80 µm internal surface...

We describe here a surgical technique of removing the remaining cortex after phacoemulsification without performing the conventional irrigation/aspiration (I/A) procedure. In this technique, the remaining cortex attached to the posterior capsule was separated and dissected into several pieces by continuous irrigation with balanced salt solution, which was supplied through a syringe attached to a bent, blunt-tip needle. Approximately, 10 s of manual irrigation separated most of the remaining cortex from the posterior capsule...

IMPORTANCE: Paracentral acute middle maculopathy (PAMM) as diagnosed by spectral domain optical coherence tomography (SD-OCT) may be associated with "patch off" visual loss post cataract surgery. BACKGROUND: To report a case series of severe vision loss due to PAMM after cataract surgery DESIGN: Retrospective case series. PARTICIPANTS: Cases from five surgical centres (public and private) in Victoria, Australia. METHODS: Retrospective analysis of cases with unexplained "patch-off" vision loss post cataract surgery...
