Abstract: Disclosed are methods for forming targeted collagen products having an amplified desired characteristic, including the step of adding peptides exhibiting a desired characteristic to collagen to form the targeted collagen product. The adding step is performed so that the collagen is crosslinked to the peptide exhibiting the desired characteristic. Crosslinking of the collagen to the peptide exhibiting the desired characteristic occurs by modification of the peptide to facilitate binding to the collagen. Further disclosed are methods for forming a targeted collagen product lacking an undesired characteristic, including the step of subtracting peptides exhibiting the undesired characteristic from collagen to form the targeted collagen product. Also disclosed are targeted collagen products formed by the disclosed methods.

The contact lens is made of a silicone hydrogel copolymer, and the solution includes a stabilizing agent in an amount effective to inhibit changes in physical properties of the silicone hydrogel copolymer.

Abstract: The present invention relates to a novel eye-drop solution that has superior microbe and bacteria management properties. Regular use in the eye will prevent bacteria from being attached to the eye. Regular use of the eye-drops will also prevent growth of microbes in the eye. A patient that uses this invention can slow the progression of infection and growth of microbes between cleaning. For disposable contact lenses the antimicrobial management properties reduces the risk of infection during the extended wear period. In one embodiment, there is a method of treating contact lenses comprising administering to the lens an ophthalmically safe composition comprising an amount of antimicrobial agent that prevents growth of microbes in the eye but is a less than the minimum disinfecting amount.

Abstract: This invention relates generally to a method for treatment of lens surfaces by first coating the mold material with a reactive macromonomer and subsequently casting and curing the lens forming material along with the coating material present on the surface of the mold. The macromonomer reacts with the lens monomer mix and is covalently bound to the lens matrix. The modified lenses may ultimately show enhanced wettability, inhibition of bacterial adhesion and lower levels of protein and lipid deposition leading to increased comfort and longer wearing times.
