Abstract

An intraocular lens with a hydrophilic polymer coating composition and methods for using same are provided. Specifically, a composition suitable for reducing tackiness in intraocular lens is provided wherein an acrylic intraocular lens is treated by vapor deposition with an alkoxy silyl terminated polyethylene glycol polymer composition. Methods for making an intraocular lens with a hydrophilic polymer coating are also provided.

Claims

1. An intraocular lens having a non-tack coating comprising a polyethylene glycol polymer having a plurality of monomers of the structure of Formula 1:

2. The intraocular lens of claim 1 wherein said halogen is selected from the group consisting of Cl, Br and I.

3. The intraocular lens of claim 1 wherein said alkoxy group is methoxy or ethoxy.

4. The intraocular lens of claim 3 wherein R₁, R₂ and R₃ all comprise methoxy groups.

5. The intraocular lens of claim 1 wherein x is an integer between 2 and 5.

6. The intraocular lens of claim 1 wherein y is an integer between 5 and 15.

7. The intraocular lens of claim 1 wherein said non-reactive group is a low molecular weight alkyl group.

8. The intraocular lens of claim 7 wherein said low molecular weight alkyl group is methyl.

9. The intraocular lens of claim 1 wherein said monomer has the structure of Formula 2:

10. A method for providing an intraocular lens surface with a hydrophilic polymer coating comprising:

applying at least one hydrophilic polymer coating to at least one surface of said intraocular lens using vapor deposition.

11. The method according to claim 10 wherein said at least one hydrophilic polymer coating is comprised of monomers having the structure of Formula 1:

12. The method according to claim 11 wherein said halogen is selected from the group consisting of Cl, Br and I.

13. The method according to claim 11 wherein said alkoxy group is methoxy or ethoxy.

14. The method according to claim 13 wherein R₁, R₂ and R₃ all comprise methoxy groups.

15. The method according to claim 11 wherein x is an integer between 2 and 5.

16. The method according to claim 11 wherein y is an integer between 5 and 15.

17. The method according to claim 11 wherein said non-reactive group is a low molecular weight alkyl group.

18. The method according to claim 17 wherein said low molecular weight alkyl group is methyl.

19. The method according to claim 11 wherein said monomer has the structure of Formula 2:
