Osteo-Odonto-Keratoprosthesis (OOKP) for patients with corneal blindness: A review

Anatomically, the cornea is the outermost layer of the eye and is primarily responsible for light refraction which allows for central and peripheral vision. Corneal diseases are among the major causes of global blindness, secondary to cataracts. This paper intends to review Osteo-Odonto Keratoprosthesis (OOKP), which is a two stage procedure whereby dental and buccal tissue is auto-transplanted into eye to serve as a synthetic cornea. Our purpose is to inform readers about the relevant anatomy, two-stage procedure, surgical inter-professionalism, indications, contraindications, complications, long-term functional and anatomical results and patient outcomes of OOKP. The present manuscript was constructed by extensive review of literature of various review articles and case reports and the data was collected from 32 review articles and case reports.
