The present invention provides an optically clear, hydrophilic coating upon the surface of a silicone medical device by sequentially subjecting the surface of the lens to plasma polymerization in a hydrocarbon-containing atmosphere and then covalently attaching a preformed hydrophilic polymer to the surface of the carbon coating. The invention is especially useful for forming a biocompatible coating on a silicone contact lens.
La présente invention se rapporte à un procédé de formation d'un revêtement hydrophile, optiquement transparent, à la surface d'un dispositif médical en silicone, qui consiste à soumettre séquentiellement la surface de la lentille à une polymérisation par traitement au plasma au sein d'une atmosphère contenant un hydrocarbure puis à fixer par liaison covalente un polymère hydrophile préformé à la surface du revêtement de carbone. Cette invention s'avère particulièrement utile à la formation d'un revêtement biocompatible à la surface d'une lentille de contact en silicone.
