US Classification:

522156

Abstract:

In vivo polymerizable intraocular lens compositions which comprise substituted fluoroalkyl or perfluoroalkyl monomers having anionic, cationic, and/or nonionic surface active functionality in the unsaturated fluorophobic ends. The compositions are preferably cured by UV photoinitiation and are useful in repairing torn or detached retinal tissue or forming intraocular lenses in situ.

International Classification:

A61K 3174
A61K 4730

US Classification:

424 7804

Abstract:

Ophthalmic compositions containing biocompatible, bioadhesive polymerizable amphipathic mesophase materials useful for repairing retinal tissue tears or retinal detachments are disclosed. In one embodiment, the polymerizable materials, which comprise substituted fluoroalkyl or perfluoroalkyl monomers having anionic, cationic, and/or nonionic surface active functionality in the unsaturated fluorophobic ends, are polymerized in vivo to provide effective, long-lasting repair of torn, ruptured or detached retinal tissue. Ophthalmic applications of these materials are not limited to retinal repair.
