Beschreibung
Zusammenfassung:	A soft contact lens comprising a silicone-hydrogel made by curing a reaction mixture comprising a silicone-containing monomer. A soft contact lens comprising a silicone-hydrogel made by curing a reaction mixture comprising a silicone-containing monomer having the structure, wherein R51 is H or CH3, q is 1 or 2 and for each q, R52, R53 and R54 are independently ethyl, methyl, benzyl, phenyl or a monovalent siloxane chain comprising from 1 to 100 repeating Si-O units, p is 1 to 10, r=(3-q), X is O or NR55 is H or a monovalent alkyl group with 1 to 4 carbons, a is 0 or 1, and L is a divalent linking group of C2-5 alkylene which may comprise ether or hydroxyl groups.
