    摘要: A composition of matter and method for preparation of a tissue augmentation material. A polysaccharide gel composition is prepared with rheological properties selected for a particular selected application. The method includes preparing a polymeric polysaccharide in a buffer to create a polymer solution or gel suspending properties in the gel and selecting a rheology profile for the desired tissue region.

    摘要: Methods of increasing the permeability of corneal epithelium to facilitate the diffusion of agents into the collagen fibrillar network of the stroma are provided. Used in combination, these methods open the epithelium to facilitate diffusion of stabilization molecules into the stroma and dissociate bridging molecules from stromal collagen fibers, thereby priming the collagen fibrillar network for restabilization by stabilization molecules. These methods can be used to increase the effectiveness and longevity of non-invasive corneal reshaping, such as orthokeratology, for correcting myopia, hyperopia and astigmatism.

    摘要: A method for treating animal tissue with acylation agents to alter the net charge and net charge density of the treated tissue for therapeutic applications is provided. The method involves applying an alkaline solution to the exposed tissue surface area. This results in deprotonation of ε-amino groups of lysine residues on the exposed tissue proteins so that the tissue proteins have a net charge. Then, an acylating agent is applied and the acylating agent reacts with the tissue protein to form a protein complex having an altered net charge. Acylating agents such as sulfonic acids, sulfonyl chlorides, and acid chlorides can be used. The method can be used to treat a wide variety of human tissues including the human cornea for correcting myopia. The method can also be used to treat skin tissue, so that there is an increase in dermal thickness and pliability. The method can be further used to treat articular cartilage.
