The Patent Description & Claims data below is from USPTO Patent Application 20080141628, Packaging solutions.

1. A method of preparing a package comprising a storable, sterile ophthalmic device, the method comprising: (a) immersing an ophthalmic device in an aqueous packaging solution comprising hyaluronic acid or salt thereof, wherein the aqueous packaging solution has an osmolality of at least about 200 mOsm/kg and a pH in the range of about 4 to about 9; (b) packaging the solution and the device in a manner preventing contamination of the lens by microorganisms; and (c) sterilizing the packaged solution and device.

2. The method of claim 1, wherein the ophthalmic device is a contact lens.

3. The method of claim 1, wherein the ophthalmic device is a silicone hydrogel contact lens.

4. The method of claim 1, wherein the hyaluronic acid or salt thereof has a number average molecular weight of about 10,000 to about 10,000,000.

5. The method of claim 1, wherein the hyaluronic acid or salt thereof has a number average molecular weight of about 50,000 to about 2,000,000.

6. The method of claim 1, wherein the hyaluronic acid or salt thereof has a number average molecular weight of about 100,000 to about 1,000,000.

7. The method of claim 1, wherein the concentration of the hyaluronic acid or salt thereof in the aqueous packaging solution is about 0.001 to about 1% w/w.

8. The method of claim 1, wherein the concentration of the hyaluronic acid or salt thereof in the aqueous packaging solution is about 0.05 to about 0.5% w/w.

9. The method of claim 1, wherein the concentration of the hyaluronic acid or salt thereof in the aqueous packaging solution is about 0.1 to about 0.3% w/w.

10. The method of claim 1, wherein the aqueous packaging solution further comprises a buffering agent.

11. The method of claim 1, further comprising hermetically sealing the ophthalmic device and the aqueous packaging solution in the package.

12. The method of claim 11, wherein heat sterilization is performed subsequent to sealing of the package.

13. The method of claim 1, wherein the aqueous packaging solution does not contain an effective disinfecting amount of a disinfecting agent.

14. The method of claim 1, wherein the aqueous packaging solution does not contain a germicide compound.

15. The method of claim 1, wherein the aqueous packaging solution does not contain a surfactant.

16. The method of claim 13, wherein the aqueous packaging solution further does not contain a surfactant.

17. A packaging system for the storage of an ophthalmic device comprising a sealed container containing one or more unused ophthalmic device immersed in an aqueous packaging solution comprising hyaluronic acid or a salt thereof, wherein the solution has an osmolality of at least about 200 mOsm/kg, a pH of about 4 to about 9 and is heat sterilized.

18. The packaging system of claim 17, wherein the ophthalmic device is a contact lens.

19. The packaging system of claim 17, wherein the ophthalmic device is a silicone hydrogel contact lens.

20. The packaging system of claim 17, wherein the hyaluronic acid or salt thereof has a number average molecular weight of about 10,000 to about 10,000,000.

21. The packaging system of claim 17, wherein the hyaluronic acid or salt thereof has a number average molecular weight of about 50,000 to about 2,000,000.

22. The packaging system of claim 17, wherein the hyaluronic acid or salt thereof has a number average molecular weight of about 100,000 to about 1,000,000.

23. The packaging system of claim 17, wherein the concentration of the hyaluronic acid or salt thereof in the aqueous packaging solution is about 0.001 to about 1% w/w.

24. The packaging system of claim 17, wherein the concentration of the hyaluronic acid or salt thereof in the aqueous packaging solution is about 0.05 to about 0.5% w/w.

25. The packaging system of claim 17, wherein the concentration of the hyaluronic acid or salt thereof in the aqueous packaging solution is about 0.1 to about 0.3% w/w.

26. The packaging system of claim 17, wherein the aqueous packaging solution further comprises a buffering agent.

27. The packaging system of claim 17, wherein the package is heat sterilized subsequent to sealing of the package.

28. The packaging system of claim 17, wherein the aqueous packaging solution does not contain an effective disinfecting amount of a disinfecting agent.

29. The packaging system of claim 17, wherein the aqueous packaging solution does not contain a germicide compound.

30. The packaging system of claim 17, wherein the aqueous packaging solution does not contain a surfactant.

31. The packaging system of claim 28, wherein the aqueous packaging solution further does not contain a surfactant.

32. A method of treating an ophthalmic lens, the method comprising storing the lens in an aqueous packaging solution comprising hyaluronic acid or a salt thereof, wherein the aqueous packaging solution does not contain an effective disinfecting amount of a disinfecting agent.
