PURPOSE: To compare the intraoperative parameters and postoperative outcomes using two different phaco handpieces with different energy delivery systems of the same phacoemulsification machine. METHODS: One hundred and sixty eyes of 160 cataract patients were randomly assigned to 2.40 mm phacoemulsification using the AMO WhiteStar Signature(®) phaco system with the standard phaco handpiece (Group 1) or the Ellips FX phaco handpiece (Group 2). According to the lens opacities classification system III, each group was divided into four subgroups of 20 patients each...

PURPOSE: To assess the impact of sequential and combined surgery [cataract surgery and 23-gauge pars plana vitrectomy (PPV) with peeling] on corneal endothelium cell density (CED) and corneal biomechanical characteristics. METHODS: Phakic eyes with epiretinal membrane (ERM) were prospectively allocated to (i) cataract surgery and subsequent PPV (CAT group), (ii) PPV and subsequent cataract surgery (VIT group) or (iii) phacovitrectomy (COMBI group). Eyes were examined at baseline, 1 month after each surgery, and at 3 and 12 months follow-up...

Our objective is to investigate which factors and patient characteristics are associated with success in Trabectome surgery.A total of 658 phakic cases with at least of 12 months follow-up were included in the analysis. Baseline demographics and medical data were collected. The main outcome measure was intraocular pressure (IOP), glaucoma medication (Rx), and secondary glaucoma surgery if any. Success was defined as IOP reduction of 20% or more from preoperative IOP and IOP < 21 mm Hg with no secondary surgery throughout the follow-up period...

Background Advanced cataract with hard lens nuclei frequently challenge the ophthalmologic surgeon when doing phacoemulsification. In the present study, we examined the effect of a new phaco tip design during cataract surgery. Patients and Methods 100 patients were assigned to two groups. In group 1 (50 patients), the Kelman(®) tip design (Alcon) was used during phacoemulsification, while in group 2 (50 patients), the Intrepid(®) Balanced Tip was applied. Trypan blue was used in both groups, if necessary, to stain the anterior lens capsule prior to capsulorhexis...

OBJECTIVE: To determine the usefulness of the SENSIMED Triggerfish(®) system in the postoperative control of combined phacoemulsification and ExPRESS implant (PHACO-ExPRESS) surgery in patients with cataract and chronic open angle glaucoma (COAG) during a 2 months follow-up. METHODS: A prospective study conducted on 15 eyes that were subjected to PHACO-ExPRESS combined surgery. Using the SENSIMED Triggerfish(®) system, two records of the circadian patterns of intraocular pressure (IOP) were performed, one before and one after surgery...

This is a prospective clinical assay that included six patients who were diagnosed with penetrating corneal injury, traumatic cataract, and posterior segment intraocular foreign body (IOFB). Following anterior segment repair and extraction of traumatic cataract by clear cornea phacoemulsification, a standard 25-gauge transconjunctival pars plana vitrectomy was performed to find and release the IOFB. With active suction using a 25-gauge silicone tipped cannula, the foreign body was retrieved and safely placed in the anterior chamber...

OBJECTIVE: To qualitatively analyse the evolution of filtering blebs after XEN surgery, by using anterior segment optical coherence tomography (AS-OCT). METHODS: A prospective study was performed on filtering blebs of 30 eyes with cataracts and glaucoma, surgically operated on using phacoemulsification and XEN45 implantation (PHACO-XEN). AS-OCT was used to analyse bleb morphology and reflectivity at 3, 6, and 12 months after surgery. Functionality was studied considering an intraocular pressure (IOP)≤18mmHg without antihypertensive medication...

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.

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...
