Abstract
A soft contact lens comprising a silicone-hydrogel made by curing a reaction mixture comprising a silicone-containing monomer.
Claims11
A soft contact lens comprising a silicone-hydrogel made by curing a reaction mixture comprising a silicone-containing monomer having the structure:
- ##STR6## wherein R.sup.51 is H or CH.sub.3, q is 1 or 2 and for each q, R.sup.52, R.sup.53, and R.sup.54 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 0 or NR.sup.5, where R.sup.5 is H or a monovalent alkyl group with 1 to 4 carbons, a is 0 or 1, and L is a divalent linking group a hydrophilic monomer, and a hydroxyalkylamine-functional 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:
- ##STR8## where b=7 to 11.
