ABSTRACT:
An orbital implant is provided with a passageway extending from the anterior surface inwardly to receive a peg prior to implantation in the patient. The peg is made of non microporous material so that surrounding tissue will encapsulate the peg without adhering to it. A cap of absorbable bio-material is placed in front of the implant so as to create a cushion between the implant and the ocular prosthesis. The peg provides for later coupling of the ocular prosthesis to the implant without the necessity of a second operative procedure, and also allows the peg to be easily removed surgically if deemed necessary by the surgeon. The implant itself can be of any suitable material, but the implant is preferably made of biodegradable material having a matrix with random voids throughout to enhance tissue ingrowth into the implant.
