Abstract

Intracorneal or epicorneal lens with a plurality of fixation holes spaced about the outer circumference of the lens. The lens can be of a soft material, such as hydrogel, a high refractive index material such as polysulfone, polycarbonate, or polyethylene, or any other material. The lens can also be coated with any suitable material, such as hydrogel or glycosaminoglycan.

Claims

1. A corneal implant lens comprising an optic having a plurality of fixation holes about a periphery, the optic including a coating of a material which enhances the growth of corneal epithelium cells into and about said holes.

2. The lens of claim 1 wherein the coating material is selected from the group of fibronectin, laminen, a glycosaminoglycan or a type IV collagen.

3. The lens of claim 2 wherein the coating is on the anterior surface of the lens.

4. A method for enhancing the growth and adhesion of corneal epithelium cells to a corneal implant lens implanted in the cornea, the method comprising providing the lens with a plurality of fixation holes about its periphery, and a coating of a material which enhances the growth of corneal epithelium cells into and about said holes.

5. The method of claim 4 wherein the material is selected from the group of fibronectin, laminen, a glycosaminoglycan or a tyoe IV collagen.

6. The method of claim 5 wherein the material is coated on the anterior surface of the lens.
