Optically transparent, soft, flexible, elastomeric, expandable hydrogel compositions and ophthalmic devices such as intraocular lenses, contact lenses and corneal inlays made therefrom are described herein. The preferred hydrogel compositions are produced through the copolymerization of one or more fluoro side-chain methacrylate end-capped silicone monomers with one or more hydrophilic monomers.
La présente invention concerne des compositions d'hydrogel extensible, élastomère, souple, mou et optiquement transparent ainsi que des dispositifs ophtalmiques tels que des lentilles intraoculaires, des lentilles de contact et des implants cornéens réalisés à partir de ces compositions d'hydrogel. Les compositions d'hydrogel préférées sont produites par la copolymérisation d'au moins un monomère de silicone à coiffe terminale méthacrylate à chaînes latérales fluoro et d'au moins un monomère hydrophile.
