Beschreibung
Zusammenfassung:	The present invention generally relates to inherently wettable silicone hydrogel contact lenses formed from a silicone hydrogel lens (101) formulation that comprises a polysiloxane vinylic crosslinker having H-donor moieties, a siloxane-containing vinylic monomer with or without H-donor moieties, and a N-vinyl amide monomer. The inherently wettable silicone hydrogel contact lenses can have a combination of the desired contact lens properties including relatively high oxygen permeability, relatively high water content, relatively low modulus, and relatively-low surface atomic Si percentage. The present invention is also related to a method for making such inherently wettable silicone hydrogel contact lenses.
