Abstract
The invention provide a new class of silicone-containing prepolymers containing dangling polysiloxane-containing polymer chains. This class of silicone-containing prepolymer is capable of being actinically crosslinked to form a silicone hydrogel material with a relatively high oxygen permeability, a reduced elastic modulus, and a relatively high ion permeability. The present invention is also related to silicone hydrogel contact lenses made from this class of silicone-containing prepolymers and to methods for making the silicone hydrogel contact lenses.
