The present invention provides a new class of silicone-containing prepolymers containing dangling polysiloxane-containing polymer chains. This class of silicone-containing prepolymers are crosslinked by actinic radiation to form silicone hydrogel materials having relatively high oxygen permeability, reduced modulus, and relatively high ion permeability. The present invention also relates to silicone hydrogel contact lenses made from this class of silicone-containing prepolymers and methods for making the silicone hydrogel contact lenses. |
