CA 2582510
The present invention relates to wettable silicone hydrogels comprising the reaction product of at least one siloxane containing component and at least one reactive, hydrophilic polymeric internal wetting agent. The present invention further relates to silicone hydrogel contact lenses comprising at least one oxygen permeable component, and an amount of reactive, hydrophilic polymeric internal wetting agent sufficient to impart wettability to said device.
L'invention porte sur des silicones hydrogels mouillables comprenant le produit réactionnel d'au moins un composant contenant du siloxane et d'au moins un agent mouillant polymère hydrophile et réactif interne. L'invention concerne en outre des lentilles de contact en silicone hydrogel renfermant au moins un composant perméable à l'oxygène et une quantité d'un agent mouillant polymère hydrophile et réactif interne suffisante pour conférer une mouillabilité au dispositif.
