Disclosed is a method of insertion of keratoprostheses, and in particular, a method of surgical insertion and placement of a soft hydrogel prosthetic corneal device into the host cornea. The method of the invention provides a greatly improved rate of success for the implantation and retention of the device.

Method of insertion of keratoprostheses

The invention provides an ocular socket prosthesis comprising a hydrogel consisting essentially of a biocompatible hydrophilic polymer onto which tissues can be directly sutured. Preferably the prosthesis comprises the polymer both in its homogeneous gel form and in its sponge form, and the two forms are chemically joined at their interface via an interpenetrating polymer network (IPN). However, it is also contemplated that the prosthesis of the invention may be made predominantly or entirely from the sponge form of the polymer. Methods of production of the prosthesis of the invention and of surgical implantation are also disclosed and claimed.
