Orbital Rim Implants
Definition : Ophthalmic implants designed for the total or partial reconstruction and/or augmentation of the extraocular rim, including the inferior (i.e., orbital floor), lateral (i.e., orbital wall), and superior parts of the rim. These implants are manufactured in a variety of sizes and shapes according to the intended use; they are typically made of high-density polymers (e.g., polyethylene) that are frequently reinforced with an embedded metal (usually titanium) mesh. The implants can be trimmed to fit the patient's orbital anatomy. Dedicated orbital rim implants are available for use in procedures such as reconstruction of the orbital floor and wall augmentation of the inferior and lateral rim, augmentation of the lateral and superior or orbital rims in patients who are hypoplasic, and to support the lower eyelid and lateral canthus in patients who have inadequate support. These implants are used mainly to repair traumatic damage (e.g., fractures), to improve the function of the eyes, or for cosmetic and/or reconstructive reasons.
