A Simplified Method to Fabricate a Pneumatic Ocular Prosthesis for Large Ocular Defects.

When an enucleation or exenteration procedure removes the entire orbital contents but not the eyelids, an abnormally large orbital socket is created that would require an equally sized volume enhancing, flush fitting ocular prosthesis. The solid acrylic prosthesis would rest on or in the lower fornix and owing to its weight, causes distortion of the lower eyelid and/or asymmetrical alignment of the entire palpebral fissure. The aim of this article was to describe a method of fabricating a pneumatic light weight custom ocular prosthesis using lost wax technique to overcome the deteriorating effects of conventional solid ocular prosthesis.
