4. Nonintegrated implants They do not have a surface where rectus muscles can be anchored, nor they allow fibrovascular tissue to grow in them (this is why we call them nonintegrated). They include implants made of glass, rubber, iron, acrylic material, silicone, gold, silver, or polymethylmethacrylate [28]. Their only function is to replace the volume loss and to improve the cosmetic result. If the surgeon wants to increase the motility of the implant and, consequently, of the prosthesis, the rectus muscles should be repositioned and sutured to the anterior pole of the implant in order to move the artificial eye when the implant moves.

Artificial eyes have enormously improved the psychological impact and the physical image of the person who undergoes this mutilating surgery. It was back in 1885 when Mules suggested the idea of placing orbital implants in these orbits [4]. Later on, Frost used hollow glass spheres as orbital implants. The surgical procedure was slightly modified with time. It was not until 1972 when Soll [19] suggested placing the implant beneath Tenon’s capsule. Helveston covered the implant with donor sclera.

Retrobulbar or intraorbital anesthesias are forbidden when tumors or infections are present. 2. Intravenous antibiotic is usually used 30 min prior to surgery in the presurgery prepara‐ tion area. 3. 4/0 silk sutures (two per eyelid) are placed on the eyelid border to provide traction. We recommend long bits with the needle as traction later on in the surgery may tear the tarsal and skin tissues. 4. With a scalpel blade (number 11 or 15) or with an electrocautery, incise the skin in an elliptical fashion trying to follow the inner surface of the orbital rim (Figure 21).
