Abstract:
The present invention relates to silicone hydrogels exhibiting desired combinations of physical and mechanical properties, formed from a reactive monomer mixture comprising at least one N-alkyl methacrylamide, and at least one silicone-containing component. These silicone hydrogels may also contain hydrophilic components, crosslinking agents and toughening monomers. These silicone hydrogels are useful in preparing biomedical devices, ophthalmic lenses, and contact lenses.
