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 rec
