In recent years, sutureless aortic valves have grown in popularity. As these valves do not need to be anchored with sutures, shorter cardiac ischaemia and extracorporeal circulation times can potentially be achieved. In addition, the absence of a sewing ring in these valves results in a greater effective orifice area for any given size. Postoperative outcome may be improved using sutureless val...

When vitrectomy is performed in eyes that have undergone glaucoma surgery, the site of sclerotomy often overlaps with the previous glaucoma operation site. It can lead to serious complications such as postoperative hypotony, leakage, and/or infection. Our technique involves modification of surgeon's position and two sclerotomy sites 45° away from the original position, with an infusion cannula ...

PURPOSE To report the efficacy of 23-gauge (G) pars plana vitrectomy with silicone oil injection in rhegmatogenous retinal detachment. METHODS Retrospective chart review of consecutive patients with retinal detachment who underwent pars plana vitrectomy by one of two surgeons using distinct and consistent methods. All patients undergoing 23-G pars plana vitrectomy did not have scleral bucklin...

Purpose: The aim of this study was to compare the rate and location of intraoperatively induced retinal breaks between two techniques of standard 20-gauge vitrectomy and transconjunctival 23-gauge using trocar/cannula Methods: In this prospective comparative case series patients having attached retina before surgery who were operated for different vitreoretinal or macular conditions by standard...

PURPOSE To assess the occurrence and magnitude of corneal topographic changes in phakic eyes undergoing Transconjuctival Cannulated 20 gauge Vitrectomy (TC20V) without scleral buckling or silicone oil tamponade. SETTING Prospective randomized controlled study done at Egyptian Eye Academy. METHODS Forty eyes of 40 patients underwent TC20V for a variety of vitreo-retinal conditions over a 1 y...

AIM To report our initial experience with lens-sparing vitrectomy for stage 4 retinopathy of prematurity using the 27-gauge (G) system. METHODS This retrospective case series involved nine eyes of five babies with active stage 4 ROP, who underwent 27-G lens-sparing vitrectomy. Surgery was done using 27-G valved cannulas and sclerotomies were made 1.5 mm from the limbus. Bilateral sequential v...
