Abstract

Compositions and methods for caring for a contact lens include an inositol phosphate component in an amount effective to at least facilitate the beneficial treatment of the lens.

Claims

1. A composition effective for disinfecting a contact lens comprising:

a liquid aqueous medium;

a disinfectant component present in said liquid aqueous medium in an amount effective to disinfect a contact lens contacted with said composition; and

an inositol phosphate component present in said liquid aqueous medium in an amount effective to remove proteinaceous deposit material from a contact lens contacted with said composition, said composition being free of TYPE II endoglycosidase.

2. The composition of claim 1 wherein said inositol phosphate component is selected from the group consisting of phytic acid, salts of phytic acid, complexes of phytic acid and mixtures thereof.

3. The composition of claim 1 wherein said disinfectant component is a non-oxidative disinfectant.

4. The composition of claim 1 wherein said inositol phosphate is present in an effective chelating amount and said composition is free of EDTA.

5. The composition of claim 1 which further comprises a surfactant component in an amount effective to remove deposit material from a contact lens contacted with said composition.

16. A method for disinfecting a contact lens comprising contacting contact lens with the composition of claim 1 at conditions effective to disinfect said contact lens.

6. A composition effective for disinfecting a contact lens comprising:

a liquid aqueous medium;

a disinfectant component present in said liquid aqueous medium in an amount effective to disinfect a contact lens contacted with said composition; and

an inositol phosphate component present in said liquid aqueous medium in an amount effective to act as a chelating agent, said composition being free of TYPE II endoglycosidase.

7. The composition of claim 6 wherein said inositol phosphate component is selected from the group consisting of phytic acid, salts of phytic acid, complexes of phytic acid and mixtures thereof.

8. The composition of claim 6 which further comprises a surfactant component in an amount effective to remove deposit material from a contact lens contacted with said composition.

9. The composition of claim 6 which is free of EDTA, and said disinfectant component is a non-oxidative disinfectant.

17. A method for disinfecting a contact lens comprising contacting contact lens with the composition of claim 6 at conditions effective to disinfect said contact lens.

10. A composition effective for treating a contact lens comprising:

a liquid aqueous medium adapted to contact a contact lens in treating the contact lens; and

an inositol phosphate component selected from the group consisting of phytic acid, salts of phytic acid, complexes of phytic acid and mixtures thereof present in said liquid aqueous medium in an amount effective to facilitate the treating of a contact lens contacted with said composition, said composition being free of TYPE II endoglycosidase.

11. The composition of claim 10 wherein said inositol phosphate component is present in an amount effective to facilitate removal of deposit material from a contact lens contacted with said composition.

12. The composition of claim 10 wherein which further comprises a surfactant component in an amount effective to remove deposit material from a contact lens contacted with said composition.

13. The composition of claim 10 which further comprises an enzyme component effective to remove proteinaceous deposit material from a contact lens contacted with said composition.

18. A method for treating a contact lens comprising contacting a contact lens with the composition of claim 10 at conditions effective to provide the desired treatment to said contact lens.

14. A composition comprising at least one solid article including an inositol phosphate component which is soluble in a liquid aqueous medium used to contact a contact lens in cleaning the contact lens and an enzyme component effective to remove proteinaceous deposit material from a contact lens in an amount effective to remove proteinaceous deposit material from the contact lens contacted with a liquid medium containing said composition in released form, said composition being free of TYPE II endoglycosidase.

15. The composition of claim 14 wherein said inositol phosphate component is selected from the group consisting of phytic acid, salts of phytic acid, complexes of phytic acid and mixtures thereof.

19. A method for cleaning a contact lens comprising contacting a proteinaceous deposit material-containing contact lens with a liquid aqueous medium combined with the composition of claim 14 at conditions effective to remove proteinaceous deposit material from said proteinaceous deposit material-containing contact lens.

20. A method for cleaning a contact lens comprising contacting a proteinaceous deposit material-containing contact lens with a composition comprising a liquid aqueous medium and an inositol phosphate component present in a solubilized form in said liquid aqueous medium in an amount effective to remove proteinaceous deposit material from a contact lens in contact with said composition, said contacting occurring at conditions effective to remove proteinaceous deposit material from said proteinaceous deposit-containing contact lens, said composition being free of TYPE II endoglycosidase.
