Abstract
Described are silicone hydrogels with high levels of polyamides exhibiting an excellent balance of physical, mechanical, and biological properties. The silicone hydrogels are formed from a reactive monomer mixture comprising: a hydroxylalkyl (meth)acrylate monomer; hydroxyl-containing silicone components; and a polyamide, wherein the polyamide is present in an amount greater than 15 weight percent, based on the total weight of reactive components in the reactive monomer mixture.
