Surface active prepolymers with both fluorine-containing groups and hydrophilic groups
Provided are surface modified contact lenses formed from one or more fumaric- or itaconic-containing prepolymers having polymerizable functionality that is complimentary to polymerizable hydrophilic polymers.
1. A hydrogel comprising a polymerized monomer mix of a polymerizable monomer mixture comprising at least one prepolymer of the following structure:
YCO—CH═CHCOXOCCH═CH—COY (I)
and
CH 2 ═C(CH 2 COY)—COXOC(CH 2 COY)C═CH 2 (II)
wherein Y is a group derived from a reactive oligomer of hydrophilic monomers and X is derived from a reactive fluoroether.
2. A medical device comprising the hydrogel of claim 1 .
3. The medical device of claim 2 wherein the medical device has at least one of the properties selected from the group consisting of oxygen permeable, hydrolytically stable, biologically inert, and transparent.
4. The medical device of claim 2 wherein the medical device is polymerized to form three-dimensional networks which permit the transport of oxygen.
5. The medical device of claim 2 wherein the medical device is polymerized to form an optically clear, strong and hydrophilic medical device.
6. The medical device of claim 2 wherein the medical device is an ophthalmic lens.
7. The medical device of claim 6 wherein the medical device is a contact lens.
8. The medical device of claim 2 wherein the medical device is an intraocular lens.
