Modified osteo-odonto keratoprosthesis (MOOKP) is difficult two step surgical procedure. Initially, we must recognize why it is useful for visual recovery of end-stage optical outside diseases like Stevens- Johnson disease.
MOOKP have a lot of advantages compared to other K-pros, for instance the using auto tissue of canine tooth root and buccal mucous covering, the fixed unions between visual tube and canine tooth root, the bond between MOOKP lamina and sclera or cornea, the strong optical surface by auto buccal mucous membrane, no swelling on the back of visual cylinder and so on.
The modified OOKP (MOOKP) is mainly a 2-step process. The first step entails elimination of the patient’s canine tooth, and it is intended to grip the lens. After that, the tooth is placed in a pocket, which is formed below the skin of the standard eye. A little part of mucous membrane is than detached from the inside of the cheek and affixed to the sclera of the wounded eye.
Five-months afterward, the 2nd step of the process is performed. By now, the tooth, which is sheltered by soft tissue is detached from the pocket below the standard eye and positioned behind the mucous membrane of the injured eye, such that only the lens protrude out of the eye.
Patients with sightlessness due to severe chemical burns, trachoma, Stevens-Johnson disease, optical cicatricial pemphigoid, various corneal graft failures etc need a keratoprosthesis or a substitute of their natural cornea. In lots of such cases a keratoplasty (substitute of cornea from a corpse) will not work because of the high rate of elimination. The only appropriate substitute is a keratoprosthesis and a modified Osteo-odonto-keratoprosthesis (OOKP) is the top selection in such cases.
