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.
