Abstract

See full text

The invention provides an actinically-polymerizable amphiphilic polysiloxane which comprises a polysiloxane polymer chain comprising a polylsiloxane segments comprising at least one siloxane unit having a low molecular weight hydrophilic polymer chain connected with a silicone atom of the siloxane unit, and (meth)acrylamido groups each covalently bonded to one of the ends of the polysiloxane polymer chain and/or to the end of one of low molecular weight hydrophilic polymer chains each connected with one silicone atom. The present invention is also related to a polymer, an actinically-crosslinkable silicone-containing prepolymer, a silicone hydrogel polymeric material, or a silicone hydrogel contact lens, which comprises repeating units derived from an actinically-polymerizable amphiphilic polysiloxane of the invention. In addition, the invention provides a method for making silicone hydrogel contact lenses using a water-based lens-forming formulation comprising an actinically-polymerizable amphiphilic polysiloxane of the invention and/or an actinically-crosslinkable silicone-containing prepolymer of the invention.
