Hyaluronic acid in the enhancement of lens regeneration
First Claim
1. A method for enhancing regeneration of lens cells in a mammal, the method comprising the steps of:
- providing a composition comprising a hyaluronic acid compound wherein said hyaluronic acid is a crossed-linked hyaluronic acid selected from the group consisting of a cross-linked form of a stabilized hyaluronic acid and a non-animal stabilized hyaluronic acid; 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 and further wherein the hyaluronic acid provides an internal scaffold for the proliferation and differentiation of regenerating lens fiber to improve the configuration, shape and structure of regenerated lenses.

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.
