A variety of alloplastic and natural substances have been utilized for support of the orbital floor following a blowout fracture. The employment of Gelfilm is herein recommended for the smaller floor defects. Sterile Gelfilm is manufactured from denaturated collagen, is 0.075 mm. thick, and is known to be tolerated well by ocular tissues. Complete absorbsion of Gelfilm occurs in two to three months, obviating the need for removal of a prosthetic material or the lifetime presence of an alloplast in the orbit. In contrast to autografts no additional surgery is required for its preocurement.
