Abstract: A collagen-hydrogel for promoting epithelial cell growth and regeneration of the stroma is shown. Also shown is an optical lens for the eye, fabricated from the collagen-hydrogel, which, when affixed to Bowman's membrane, promotes and supports epithelial cell growth, enables corneal epithelium of the cornea of an eye, during the healing process, to attach to and cover the anterior surface of the lens implanting the same and to regenerate the stroma which grows over the edge of and attaches to the optical lens. Laid down in the layers of the regenerated stroma are new keratocytes and collagen fibial produced from keratocytes. The collagen-hydrogel is a hydrogel polymer formed by the free radical polymerization of a hydrophilic monomer solution gelled and crosslinked in the presence of an aqueous stock solution of collagen to form a three dimensional polymeric meshwork for anchoring collagen. The collagen-hydrogel material has a ratio by weight of collagen-to-hydrogel in the range of about 0.

Abstract: A method of making a collagen-hydrogel is shown. The method comprises the steps of forming a radical free polymer of a hydrophilic monomer; mixing the hydrophilic monomer with a stock solution of collagen in the presence of a weak solution of ammonium persulfate and sodium metabisuleate forming a clear viscous monomer solution; and heating said viscous monomer solution in the presence of a crosslinking agent to polymerize the same into a three dimensional polymeric meshwork having collagen from the stock solution of collagen interdispersed within the three dimensional polymeric meshwork.

Abstract: A method for locating on a cornea an artificial lens fabricated from a collagen-hydrogel for promoting epithelial cell growth and regeneration of the stroma is shown. The method provides for affixing an artificial lens to the Bowman's membrane and the lens, during the healing process, promotes and supports epithelial cell growth enabling corneal epithelium of the cornea of an eye to attach to and cover the anterior surface of the lens implanting the same and to regenerate the stroma which grows over the edge of and attaches to the optical lens. Laid down in the layers of the regenerated stroma are new keratocytes and collagen fibial produced from keratocytes.

Abstract: A method for locating on the cornea an optical lens having a preselected geometric shape and power wherein the optical lens is formed of a collagen-hydrogel for promoting epithelial cell growth is shown. The method comprises the steps of: removing from Bowman's membrane over the area of the pupillary zone of the eye a portion of the corneal epithelium; forming on Bowman's membrane a "V" shaped annular groove having a diameter substantially equal to the maximum geometrical dimensions of the optical lens and a preselected depth; dissecting the peripheral edge of the groove forming a wing of corneal tissue having a preselected length; placing the posterior surface of the optical lens on the anterior surface of Bowman's membrane and positioning the outer edge of the optical lens under the corneal wing, and affixing the optical lens to Bowman's membrane over the pupillary zone of the eye to maintain the same on the cornea with the corneal wing overlying the edge of the optical lens.

Abstract: A collagen-hydrogel for promoting epithelial cell growth is shown. Also shown is an optical lens for the eye, fabricated from the collagen-hydrogel, which, when affixed to Bowman's membrane, promotes and supports epithelial cells growth and enables corneal epithelium of the cornea of an eye, during the healing process, to attach to and cover the anterior surface of the lens implanting the same. The collagen-hydrogel is a hydrogel polymer formed by the free radical polymerization of a hydrophilic monomer solution gelled and crosslinked in the presence of an aqueous solution of macromolecules to form a three dimensional polymeric meshwork for anchoring macromolecules. Macromolecules comprising a constituent of a ground substance of tissue, which in the preferred embodiment is a native collagen, are interspersed within the polymeric network forming the hydrogel resulting in a collagen-hydrogel for promoting epithelial cell growth.
