ABSTRACT:
An orbital implant and conformer affords mobility and decreases the likelihood of implant extrusion and the "dropped socket" appearance. The implant device consists of a spherical implant whose circumference is dotted with a cellular ingrowth surface to which all the remaining ocular muscles can adhere and act upon. A shaft protrudes anteriorly from the implant through the conjunctival sheath into the front orbital space. The base of the shaft and the area of the implant encircling the shaft also have a cellular ingrowth surface into which the conjunctiva can grow forming a tight seal. The shaft fits into a corresponding small hole in the conformer. The shaft communicates the muscular movement of the implant directly to the conformer. Since the conformer sits on the shaft, its weight is more evenly distributed throughout the orbital socket and should not distend the eyelids. The cellular ingrowth areas on the implant, on and around the base of the shaft, and at the muscle junctions, cause a close apposition of the tissues to the implant that prohibits implant migration and extrusion.
