Abstract

Synthetic surfaces such as surfaces of implantable prosthetic devices are modified to enhance their ability to support the growth, migration and attachment of epithelial cells. A surface modifier composition is covalently bound to the synthetic surface, and an epithelial cell-supporting coating is applied to the modified surface. The surface modifier composition may also include an epithelial cell-supporting material.
The invention is particularly suited towards the modification of synthetic epikeratophakia lenses.
