—The purpose of this brief letter is to give preliminary information about a laboratory technique that may prove to be of clinical importance to corneal surgeons. The experiments themselves will be published in detail at a later time, but I believe that the work has sufficient interest to present as a communication in this form.As experience with keratoprostheses evolves, attention is being focused upon posterior corneal prostheses in distinction to ones which occupy a full thickness of the central cornea. The reason is that an implant exposed to the body surface is almost always extruded within weeks, months, or years after the original operative procedure. Posterior (buried) keratoprostheses have been developed by Thomas1; Cardona et al2; and Brown and Dohlman.3 More recently, impermeable silicone membranes have been sutured to the posterior surface of corneas and donor grafts by Dohlman et al.4 Whereas
