Three types of implants have been designed, all in “vitallium,” each of them to be integrated with the same type of artificial eye so that the motion of the implant is imparted to the eye and the eye is held up to support the upper lid in a normal manner.
All the implants have the same type of face, which is left exposed in the socket, with an oval depression anteriorly. The eye is designed with an oval peg on its posterior (concave) surface to fit into this depression.
