Abstract

The present invention relates to contact lens care product comprising dexpanthenol. The invention similarly relates to the usage of a contact lens care compositions of this kind for cleaning and optionally disinfecting contact lenses.

Claims

1. Contact lens care composition comprising:

0.5 to 4 percent by weight dexpanthenol based on the total weight of the contact lens care composition;

one or more further constituents selected from the group consisting of buffer substances, substances that affect the tonicity, complexing agents and/or antimicrobial compounds; and

D-sorbitol.

2. Contact lens care composition according to claim 1, comprising 0.8 to 6 percent by weight, of D-sorbitol, based on the total weight of the contact lens care composition.

3. Contact lens care composition according to claim 2, comprising 1 to 3 percent by weight D-sorbitol, based on the total weight of the contact lens care composition.

4. Contact lens care composition comprising 0.5 to 4 percent by weight dexpanthenol based on the total weight of the contact lens care composition;

an antimicrobial agent which is a biguanide; and

D-sorbitol.

5. Contact lens care composition according to claim 4, comprising an aqueous solution comprising 0.5 to 4 percent by weight, of dexpanthenol, based on the total weight of the contact lens care composition.

6. Contact lens care composition according to claim 4, which contains

7. Contact lens care composition according to claim 4, further comprising D-sorbitol, one or more buffer substances, and a complexing agent.

8. Contact lens care composition according to claim 7, which comprises

9. Contact lens care composition according to claim 4, which further comprises a surface-active substance.

10. Contact lens care composition according to claim 5, comprising an aqueous solution comprising 1 to 3 percent by weight of dexpanthenol, based on the total weight of the contact lens care composition.

11. Method for cleaning and optionally disinfecting a contact lens, wherein a contact lens care composition according to claim 4 is brought into contact with a contact lens for a period of time that is sufficient to clean and optionally disinfect said lens.

12. Method for cleaning and optionally disinfecting a contact lens, wherein a contact lens care composition comprising dexpanthenol is brought into contact with a contact lens for a period of time that is sufficient to clean and optionally disinfect said lens.

13. Method for cleaning and optionally disinfecting a contact lens according to claim 12, wherein the contact lens care composition further comprises D-sorbitol.

14. Method for cleaning and optionally disinfecting a contact lens according to claim 12, wherein the contact lens care composition further comprises one or more further constituents selected from the group consisting of buffer substances, substances that affect the tonicity, complexing agents, and/or antimicrobial compounds.

15. Method for cleaning and optionally disinfecting a contact lens according to claim 13, wherein the contact lens care composition further comprises one or more further constituents selected from the group consisting of buffer substances, substances that affect the tonicity, complexing agents, and/or antimicrobial compounds.
