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 evaluate the optical quality of different intraocular lenses (IOLs). METHODS An optical test bench and suitable software were used to assist in analysis of the optical Fourier transform (OFT) of a test image and to determine the quality of the lens in terms of spatial frequency response. The OFT was automatically converted, by means of an(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 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 determine the influence of intraocular lens (IOL) material on anterior capsular opacification and membrane growth over the anterior IOL surface in patients who have undergone standardized small-incision cataract surgery and foldable IOL implantation in the capsular bag. DESIGN Randomized controlled trial. PARTICIPANTS Eighty-eight cataract(More)
PURPOSE To measure the working frequency and the stroke dynamics of the phaco tip of 3 phacoemulsification machines. SETTING University Eye Clinic of Trieste, Italy. DESIGN Experimental study. METHODS A video wet fixture was assembled to measure the working frequency using a micro camera and a micropulsed strobe-light system. A different video wet(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)
