Patent ID: 6943203

Claim:
A contact lens comprising a silicone hydrogel comprising a mono-alkyl terminated polydiorganosiloxane having the structure: where b=0 to 100; R 58 is a monovalent group comprising at least one ethylenically unsaturated moiety; each R 59 is independently a monovalent alkyl, or aryl group, which may be further substituted with alcohol, amine, ketone, carboxylic acid or ether groups; R 60 is a monovalent alkyl, or aryl group, which may be further substituted with alcohol, amine, ketone, carboxylic acid or ether groups, and R 61 is independently alkyl or aromatic, or a monovalent siloxane chain comprising from 1 to 100 repeating Si—O units; wherein said silicone hydrogel comprises a Young's modulus less than about 180 psi and a tan δ of equal to or less than about 0.25 at a frequency of 1 Hz at 25° C., provided that said mono-alkyl terminated polydiorganosiloxane is not a hydroxyalkylamine-functional silicone-containing monomer.
