Abstract

The present invention addresses the treatment of ocular conditions by the enhancement of lens regeneration. This is accomplished by the administration of a high viscosity composition including a hyaluronic acid compound. Excess high viscosity composition may be removed by focal laser photophacoablation. Additionally, a collagen product may be injected within the lens capsule to improve lens cell proliferation and differentiation, and to improve the configuration, shape and structure of regenerated lenses. Various embodiments involving the enhancement of lens regeneration are described. For example, lens regeneration may be enhanced by filling the lens capsule bag with the inventive hyaluronic acid compound; by inserting at least one collagen patch in the lens capsule; and/or by injecting a collagen-based product into the lens capsule.

Claims

1. A method for enhancing regeneration of lens cells in a mammal, comprising:

providing a composition comprising a hyaluronic acid compound; and

filling a lens capsule bag of said mammal with said composition,

wherein said hyaluronic acid compound is formulated to biodegrade or dissolve at least 2 weeks after being filled into said lens capsule bag.

2. The method of claim 1, further comprising:

inserting at least one collagen patch in said lens capsule bag.

3. The method of claim 1, wherein said composition is selected from the group consisting of Restylane®

, Perlane®

, and combinations thereof.

4. The method of claim 1, wherein said hyaluronic acid compound is present in said composition at a concentration of at least about 20 mg/ml.

5. The method of claim 1, wherein said composition is a gel.

6. The method of claim 1, further comprising:

injecting collagen into said lens capsule bag.

7. The method of claim 1, further comprising:

inserting a collagen-based product into said lens capsule bag, said collagen-based product being selected from the group consisting of Zyderm®

, Resoplast®

, Dermalogen® and

Alloderm®

.

8. The method of claim 2, further comprising:

phacoemulsifying a lens contained in said lens capsule bag prior to said inserting of said at least one collagen patch.

9. The method of claim 1, wherein said hyaluronic acid compound is formulated to dissolve substantially entirely by the end of 8 weeks after being filled into said lens capsule bag.

10. A method for treating an ocular condition in a mammal, comprising:

providing a composition comprising a hyaluronic acid compound; and

filling a lens capsule bag of said mammal with said composition to enhance regeneration of lens cells in said mammal, thereby treating said ocular condition,

wherein said hyaluronic acid compound is formulated to dissolve at least 2 weeks after being filled into said lens capsule bag.

11. The method of claim 10, further comprising:

inserting at least one collagen patch in said lens capsule bag.

12. The method of claim 10, wherein said composition is selected from the group consisting of Restylane®

, Perlane®

, and combinations thereof.

13. The method of claim 10, wherein said hyaluronic acid compound is present in said composition at a concentration of at least about 20 mg/ml.

14. The method of claim 10, wherein said composition is a gel.

15. The method of claim 10, further comprising:

injecting collagen into said lens capsule bag.

16. The method of claim 10, further comprising:

inserting a collagen-based product into said lens capsule bag, said collagen-based product being selected from the group consisting of Zyderm®

, Resoplast®

, Dermalogen® and

Alloderm®

.

17. The method of claim 11, further comprising:

phacoemulsifying a lens contained in said lens capsule bag prior to said inserting of said at least one collagen patch.

18. The method of claim 10, wherein said hyaluronic acid compound is formulated to biodegrade or dissolve substantially entirely by the end of 8 weeks after being filled into said lens capsule bag.

19. The method of claim 10, wherein said hyaluronic acid compound is formulated to biodegrade or dissolve substantially entirely by the time at which earliest lens fibers measurably align to allow normal lens structure and suture formation.

20. The method of claim 10, wherein said ocular condition is a cataract.

21. A method for enhancing regeneration of lens cells in a mammal, comprising:

providing a composition comprising amniotic fluid, in vitro fertilization media, or both; and

filling a lens capsule bag of said mammal with said composition.

22. The method of claim 21, further comprising:

inserting at least one collagen patch in said lens capsule bag.

23. The method of claim 21, further comprising:

injecting collagen into said lens capsule bag.

24. The method of claim 21, further comprising:

inserting a collagen-based product into said lens capsule bag, said collagen-based product being selected from the group consisting of Zyderm®

, Resoplast®

, Dermalogen® and

Alloderm®

.

25. The method of claim 22, further comprising:

phacoemulsifying a lens contained in said lens capsule bag prior to said inserting of said at least one collagen patch.

26. A novel enhanced tissue-organized composition of matter, comprising:

a mutliplicity of ribbon-like nucleus free component elements, arranged within a hexagonal pattern effective for growing into a functionally operable regenerated lens means for refracting light.

27. A regenerated composition of matter, comprising in combination:

alpha, beta, and gamma crystallins arrayed within a hexagonal matrix disposed within a capsular bag, whereby a functional light refracting lens continues to grow therefrom enabling restored visual acuity in a user.
