PURPOSE To evaluate the effectiveness and safety of a heavy silicone oil (HSO) tamponade for complicated retinal detachment (RD) surgery. DESIGN Prospective consecutive interventional case series study. PARTICIPANTS The study included 26 patients with RD complicated by severe proliferative vitreoretinopathy (PVR) in the inferior quadrants. METHODS All(More)
AimTo study the solubility of perfluorohexyloctane (F6H8) in silicone oil (polydimethylsiloxane (PDMS) 1000) and to measure the viscosity and the specific gravity of the mixture obtained (heavy silicone oil or HSO tamponade) to define the ideal ratio of these components.MethodsThe solubility diagram of the mixture was obtained with the turbidimetric method,(More)
PURPOSE To evaluate the effect of internal limiting membrane (ILM) peeling and other variables in hole closure and functional success rate after idiopathic macular hole surgery. DESIGN Retrospective, multicenter, observational study. METHODS The records of 1627 patients operated on for idiopathic macular hole were collected retrospectively from 28(More)
PURPOSE To compare the morphology and function of the corneal endothelium in the early postoperative period after extracapsular cataract extraction (ECCE) and phacoemulsification. SETTING University Eye Clinic of Trieste, Italy. METHODS In this prospective, randomized study of patients scheduled for cataract surgery, 40 patients were divided into two(More)
PURPOSE To evaluate the use of triamcinolone acetonide to stain the internal limiting membrane (ILM) during vitreoretinal surgery. METHODS A prospective clinical interventional case series study was performed, including 16 patients who underwent pars plana vitrectomy. Seven patients had proliferative diabetic retinopathy with macular edema. Seven patients(More)
PURPOSE OF REVIEW Cataract treatment is evolving, thanks to new phaco systems and innovative surgical techniques. Recent ophthalmic viscosurgical devices (OVDs) play an important role in the development of new approaches to surgery. Knowledge of the new techniques and advances in new OVDs is crucial to performing routine and complicated surgeries. RECENT(More)
PURPOSE Posterior capsule opacification (PCO) after intraocular lens (IOL) implantation has a multifactored pathogenesis. Capsulorhexis and capsular bag implantation of a one-piece, biconvex poly(methyl methacrylate) (PMMA) IOL are likely to reduce the PCO incidence. This study was performed to determine whether an ideal capsulorhexis size able to reduce(More)
BACKGROUND The implant of intraocular lenses (IOLs) following cataract surgery induces a foreign-body reaction to the IOL and a response on the part of the lens epithelial cells (LECs). The purpose of this study was to compare these aspects after the implantation of two different IOL materials. METHODS Thirty-six cataract patients were randomised to(More)
PURPOSE To evaluate corneal endothelium morphology and function after phacoemulsification using different viscoelastics. SETTING Eye Clinic, University of Trieste, Italy. METHODS This prospective, randomized study included results of preoperative and postoperative (7, 30, and 90 days) examinations of 66 patients scheduled for phacoemulsification without(More)
PURPOSE To evaluate the incidence of surface scratches on heparin-surface-modified (HSM) poly(methyl methacrylate) (PMMA) intraocular lenses (IOLs) and the possible influence of these alterations on the biocompatibility of HSM PMMA. SETTING University Eye Clinic of Trieste, Trieste, Italy. METHODS Twenty-six diabetic patients had phacoemulsification and(More)
