Abstract
Described are silicone hydrogels that are more biocompatible than current ocular materials. The silicone hydrogels are formed from a reactive monomer mixture comprising: a mixture of hydroxyl substituted silicone containing components, at least one polyamide; and at least one hydrophilic monomer. The silicone hydrogels also display a desirable balance of properties, including clarity, oxygen permeability, wettability and desirable protein uptake.
