BACKGROUND The purpose of this prospective, interventional, comparative case series was to evaluate the efficiency and feasibility of a disposable sutureless silicone lens ring for corneal contact lens stabilization during combined 23-gauge vitrectomy and cataract surgery. METHODS We developed a ring consisting of a single silicone component with three footplates along the ring margin to fit ...

Purpose. To evaluate the diurnal intraocular pressure (IOP) in eyes after vitrectomy compared to that of healthy eyes. Methods. Twenty-one patients who had undergone vitrectomy and 21 age- and gender-matched normal controls were enrolled during the same period. We measured the diurnal IOP every two hours between 9 a.m. and 11 p.m. in all patients who were admitted for cataract surgery. Patients...

PURPOSE To evaluate the vision-related quality of life (VR-QOL) and visual function following vitrectomy for proliferative diabetic retinopathy (PDR). DESIGN Prospective, interventional, consecutive, comparative case series. METHODS The 25-Item National Eye Institute Visual Function Questionnaire (VFQ-25) was answered by 51 patients with PDR before and three months after 20-gauge pars plana...

METHODS 40 cases of vitreous haemorrhage secondary to Eales' disease were taken up for vitrectomy. Depending upon duration of vitreous haemorrhage patients were divided into two groups: Group I (20 eyes) - early vitrectomy group with duration between 3-6 months; Group II (20 eyes) - deferred vitrectomy group with duration of more than 6 months. All patients were followed up for a minimum period...

There have been many advances in vitreoretinal surgery since Machemer introduced the concept of pars plana vitrectomy, in 1971. Of particular interest are the changes in the vitrectomy cutters, their fluidics interaction, the wide-angle viewing systems and the evolution of endoillumination through the past decade and notably in the last few years. The indications of 27-gauge surgery have expand...

PURPOSE Cataract progression after lens-sparing vitrectomy might differ according to original posterior segment diseases. Our objective was to analyze the refractive values after lens-sparing vitrectomy for macular hole (MH) and epiretinal membrane (ERM). MATERIALS AND METHODS We reviewed the medical records of 25 MH patients (25 eyes) and 23 ERM patients (23 eyes) who underwent lens-sparing ...

BACKGROUND/AIMS To evaluate retrospectively the clinical outcomes of patients presenting with submacular hemorrhage (SMH) secondary to neovascular age-related macular degeneration (nAMD), treated by vitrectomy, submacular tissue plasminogen activator (tPA) injection and pneumatic displacement of SMH with air followed by postoperative intravitreal ranibizumab (RZB). METHODS Patients with SMH a...

PURPOSE To compare visual outcomes, intraoperative and postoperative complications of 25-gauge transconjunctival sutureless vitrectomy (25-G TSV) versus conventional 20-gauge vitrectomy in epiretinal membrane (ERM) surgery. METHODS A retrospective comparative study was conducted on 200 eyes with idiopathic ERM who underwent either primary 20-gauge vitrectomy (n=95) or 25-G TSV (n=105) with 6 ...

Objective To evaluate the effectiveness and safety profile of combined phacoemulsification with 23G pars plana vitrectomy when compared to pars plana vitrectomy alone in phakic patients. Methods This study was performed at Al-Ehsan Eye Hospital (tertiary care eye hospital in Lahore, Pakistan) from January 2016 to August 2016. A total of 40 eyes in two equal groups of 20 eyes each, were enroll...

Background: To assess the occurrence and magnitude of refractive change in pseudophakic eyes undergoing pars plana vitrectomy without scleral buckling and to investigate possible aetiological factors. Methods: Retrospective case note review of pseudophakic eyes undergoing pars plana vitrectomy for a variety of vitreo-retinal conditions over a three-year period. Anterior chamber depth was measur...
