#1
Momoko Yamakawa, Mami Kusaka, Shogo Yamada, Masayuki Akimoto
PURPOSE: To describe a new technique for remnant removal in cases of posterior capsular rupture during cataract surgery and Soemmering ring extraction during intraocular lens (IOL) removal. METHODS: An IOL injector, inserted into the anterior chamber, provides a new exit for residual lens fragments. Passive fluid flow, supplied by an anterior chamber maintainer or some ocular viscoelastic device (OVD) injection, delivers the residual fragments into a lumen of the injector in assistance with a second device such as a phaco-chopper and vitreous cutter...

BACKGROUND: Goniosynechialysis (GSL) to remove peripheral anterior synechiae (PAS) alongside standard cataract surgery has potential theoretical advantages, Published randomised trials, however, have not shown conclusive functional benefits and aqueous outflow changes following GSL are unknown. This study aimed to compare electronic Shiøtz tonographic aqueous outflow facility (TOF) following phacoemulsification with or without GSL in patients with primary angle closure (PAC) and PAC glaucoma...

REVIEW
Andrea Mercanti, Antonio Renna
Combined cataract and vitreoretinal surgery results in better compliance in patients with posterior segment pathology and should be the preferred approach to reduce the high rate of cataract development after vitreoretinal surgery and to improve earlier visual acuity. Technological advances in both anterior and posterior segment surgery are leading to the development of instruments with a smaller diameter and more efficient tools, resulting in a minimizing of the tissue trauma related to the surgery, acceleration of functional recovery and increasing patient comfort...

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...

INTRODUCTION: Available data has highlighted the efficacy of both Phacoemulsification (PHACO) and Small Incision Cataract Surgery (SICS) in the presence of Pseudoexfoliation (PEX) syndrome. In developing countries, both are commonly performed procedures for cataract extraction. But, no direct comparison between these two procedures is available in the setting of PEX syndrome. With this lacuna in mind, this pilot study decided to compare the visual outcomes of both these techniques in the setting of PEX syndrome...

Background Combined cataract and glaucoma procedures, and minimally-invasive glaucoma surgery in particular, have gained increasing interest over the past few years. The aim of this study was to compare the long-term efficacy of combined phaco-trabeculectomy (Phaco-Trab) and combined phacoemulsification plus excimer laser trabeculotomy (Phaco-ELT). Patients and Methods Retrospective, non-randomised, comparative, interventional case series of consecutive patients after Phaco-Trab and Phaco-ELT at the University Hospital of Zurich and the Talacker Eye Center Zurich in Switzerland...

The irrigation dynamic pressure-assisted hydrodissection technique (irrigation-hydro [iH]) does not require performing manual hydrodissection using a syringe and cannula to achieve cortical-capsular cleavage during cataract surgery. Since the iH technique uses the phaco tip to intentionally vacuum the intraocular fluid in order to induce the irrigation dynamic pressure for cortical-capsular cleavage, there is a reduction in the intraocular pressure (IOP) from the bottle-height-dependent hydrostatic pressure...

PURPOSE: To compare the refractive outcome of eyes that underwent phacoemulsification combined with endoscopic cyclophotocoagulation (phaco-ECP) with the eyes that underwent phacoemulsification alone. METHODS: A retrospective case series review of 103 consecutive eyes that underwent phaco-ECP and 62 eyes that underwent phacoemulsification between January 2006 and August 2012 was conducted.

PURPOSE: The purpose was to evaluate the results of modified sleeve in phacoemulsification of cataract in completely vitrectomised eyes, Materials and Methods: Twenty-five previously completely vitrectomized eyes of 23 patients having visually significant cataract were included. After through evaluation they underwent phaco-emulsification by phaco chop with a modified sleeve via temporal clear corneal incision. The modified sleeve was made by creating a small round port of approximate 1 × 1 mm size at the proximate end of the sleeve in line with the already existing ports...

PURPOSE: We aimed to evaluate the effect of cataract surgery on subfoveal choroidal thickness (CT) and ganglion cell complex (GCC) thickness, as measured by enhanced depth imaging-optical coherence tomography (OCT). METHODS: This prospective study included 30 eyes of 30 patients who had undergone uneventful phacoemulsification surgery for senile cataract but had no previous ocular surgery or other ocular abnormality. Best-corrected visual acuity, slit-lamp biomicroscopy, intraocular pressure, axial length, and central corneal thickness were measured preoperatively...

Use of the phaco tip technique for lens cleavage and removal does not require manual hydrodissection using a syringe and cannula, or cortical removal using an irrigation/aspiration tip. The phaco tip is the only surgical instrument required for this technique. Its advantages include maintaining a stable intraocular pressure during cortical cleaving hydrodissection and lens removal, which includes the cortex.

INTRODUCTION: Corneal endothelial damage following phacoemulsification is still one of the major concerns of modern day cataract surgery. Although many techniques have been proposed, the risks of posterior capsular rupture and corneal endothelium damage persist. In theory, damage to the corneal endothelium is minimised by delivering the lowest phaco energy only in the direction necessary to emulsify the lens nucleus. Hence, it is believed that the bevel of the needle should be turned towards the nucleus or the nuclear fragment (ie, bevel-down...
