In the past, patients often had to endure the embarrassment of empty eye sockets and disfigurement of the oculofacial appearance after ocular removal, and even with a prosthetic eye fitted, the discomfort of a heavy prosthetic eye piece would eventually lead to ectropion of the lower eyelid and shallowing or even disappearance of the conjunctival sac. Since 1989, when the FDA approved hydroxyapatite for clinical use as an intraorbital filling material, hydroxyapatite eye prostheses have been widely used in ophthalmology for the past decade as an intraorbital filling after ocular removal. The hydroxyapatite (HA) prosthetic table resembles the ultrastructure of human reticular bone and has good biocompatibility and resistance to infection. After implantation, it can compensate for the orbital contents of the eye after removal and improve the appearance after installation of the simulated prosthetic eye piece.
