Enucleation techniques: the Iowa implant

The Iowa implant is a quasi-integrated implant with four mounds on its anterior surface. The rectus muscles are imbricated between the mounds, resulting in a socket with four protrusions that articulate with a custom-fitted prosthesis having four concavities. This imparts excellent motility and support for the prosthesis. This article describes the indications for enucleation, the Iowa implant, surgical technique, and postoperative complications.
