Polymers And Nanogel Materials And Methods For Making And Using The Same
Patent No. EP3296334 (titled "Polymers And Nanogel Materials And Methods For Making And Using The Same") was filed by Johnson & Johnson Vision Care on May 24, 2013. The application was issued on Jan 1, 2025.
Patent Summary
An ophthalmic device and solution that reduces lipid uptake and improves wettability and lubricity. The device comprises a silicone-containing polymer and a water-soluble, cross-linked copolymer that associates with the device surface. The copolymer is formed by RAFT polymerization of a hydrophilic monomer and a cross-linking agent, resulting in a nanogel material that remains in a macroscopically ungelled state. The copolymer has a degree of polymerization between 10 and 10,000 and lacks terminal segments that can associate with a polymeric substrate.
