Claims
- 1. A method for reducing edge glare in an implantable ophthalmic lens having an optic edge surface comprising the step of applying a hydrophilic coating material to the optic edge surface wherein the coating material comprises an ophthalmically acceptable hydrophobic (meth)acrylic polymer and an ophthalmically acceptable hydrophilic polymer in an amount sufficient to reduce or eliminate edge glare when the coating material is hydrated, and wherein the coating material has a Tg less than 37° C. when hydrated.
- 2. The method of claim 1 wherein the hydrophilic polymer is selected from the group consisting of polyhydroxyethyl methacrylate; polyacrylamide; polyglyceryl methacrylate and polyvinyl pyrrolidone.
- 3. The method of claim 2 wherein the hydrophilic polymer is polyvinyl pyrrolidone.
- 4. The method of claim 1 wherein the hydrophilic polymer has a weight average molecular weight in the range of 2,500 -100,000.
- 5. The method of claim 4 wherein the hydrophilic polymer is polyvinyl pyrrolidone having a weight average molecular weight of 10,000.
- 6. The method of claim 1 wherein the amount of the hydrophilic polymer in the coating material is about 5 -50% (wt.).
- 7. The method of claim 1 wherein the coating material has a hydrated water content of about 20-70%.
- 8. The method of claim 1 wherein the hydrophobic (meth)acrylic polymer comprises a monomer of the formula
- 9. A hydrophilic coating material for a surgical implant wherein the coating material comprises an ophthalmically acceptable hydrophobic (meth)acrylic polymer and an ophthalmically acceptable hydrophilic polymer, and wherein the coating material has a Tg less than 37° C. when hydrated.
- 10. The coating material of claim 9 wherein the hydrophilic polymer is selected from the group consisting of polyhydroxyethyl methacrylate; polyacrylamide; polyglyceryl methacrylate and polyvinyl pyrrolidone.
- 11. The coating material of claim 9 wherein the hydrophilic polymer is polyvinyl pyrrolidone.
- 12. The coating material of claim 9 wherein the hydrophilic polymer has a weight average molecular weight in the range of 2,500 -100,000.
- 13. The coating material of claim 12 wherein the hydrophilic polymer is polyvinyl pyrrolidone having a weight average molecular weight of 10,000.
- 14. The coating material of claim 9 wherein the amount of the hydrophilic polymer in the coating material is about 5 -50% (wt.).
- 15. The coating material of claim 14 wherein the amount of the hydrophilic polymer in the coating material is about 15 -30% (wt.).
- 16. The coating material of claim 9 wherein the coating material has a hydrated water content of about 20 - 70%.
- 17. The coating material of claim 9 wherein the hydrophobic (meth)acrylic polymer comprises a monomer of the formula
- 18. The coating material of claim 17 wherein the hydrophobic (meth)acrylic polymer comprises a monomer selected from the group consisting of 2-phenylethyl acrylate and 2-phenylethyl methacrylate.
- 19. The coating material of claim 9 wherein the hydrophobic (meth)acrylic polymer optionally comprises one or more ingredients selected from the group consisting of UV absorbers; blue-light blocking colorants; and chain transfer agents.
