Silicone Hydrogels Materials for Contact Lens Applications
Silicone hydrogel (Si-Hy) materials combine the benefi ts of silicone or siloxane derivates in terms of oxygen permeability and mechanical properties with those of hydrogels in terms of wettability and hidrophilicity. Such properties are critical when it comes to the application at the ocular surface in the form of contact lenses (CL) to correct visual dysfunctions, as bandage mechanism or as d...
متن کاملSurface Modification of Silicone Rubber Membrane by Microwave Discharge to Improve Biocompatibility
Wetability of biocompatible polymers can be improved by plasma surface modification. The purpose of this study was to surface modify an experimental poly (dimethylsiloxane) rubber (PDMS) material in order to improve its wetability and biocompatibility. Surface properties of the PDMS were characterized using contact angles measurement for wetability analysis. Samples of experimental silico...
متن کاملSurface functionalization of silicone rubber for permanent adhesion improvement.
The surface properties of poly(dimethyl siloxane) (PDMS) layers screen printed onto silicon wafers were studied after oxygen and ammonia plasma treatments and subsequent grafting of poly(ethylene -alt-maleic anhydride) (PEMA) using X-ray photoelectron spectroscopy (XPS), roughness analysis, and contact angle and electrokinetic measurements. In the case of oxygen-plasma-treated PDMS, a hydrophil...
متن کاملDynamic contour tonometry over silicone hydrogel contact lens.
PURPOSE This study compared the measurements of intraocular pressure (IOP) and ocular pulse amplitude (OPA) using the Dynamic Contour Tonometry (DCT) over silicone hydrogel contact lenses of different modulus. Corneal biomechanics were also measured using the Ocular Response Analyzer (ORA). METHODS Forty-seven young (mean age 22.3 years, standard deviation 1.2 years) subjects had IOP, OPA, co...
متن کاملQuantification of individual proteins in silicone hydrogel contact lens deposits
PURPOSE The aim of this study was to quantify specific proteins deposited on daily wear silicone hydrogel lenses used in combination with multipurpose disinfecting solutions (MPDSs) by applying multiple-reaction-monitoring mass spectrometry (MRM-MS). METHODS Balafilcon A or senofilcon A contact lenses used with different MPDSs on a daily wear schedule were collected. Each worn lens was extrac...
