A new vision through combined osteo-odonto-keratoplasty: A review

Abstract

This is an extensive review of osteo-odonto-keratoplasty (OOKP) where the vision is restored by using tooth as an implant in the environment of the eye. The window of the soul is our eye and the window of the eye is cornea. This review article aims at discussing the remarkable operation to regain the sight of patients with corneal blindness. In this procedure where a multidisciplinary approach from both oral and maxillofacial surgeon and ophthalmologist contributes to restore vision in the most severe cases of corneal blindness. This involves removing a canine tooth from the patient, shaping and drilling to allow implantation of an artificial plastic corneal device and finally implanting back into the eye few months later. The OOKP, is the keratoprosthesis of choice for end-stage corneal blindness not amenable to penetrating keratoplasty. This transplantation procedure has an autologous dental root-bone lamina complex and buccal mucosal graft to secure the optical cylinder which acts as a ray of vision for corneal blindness. This review comprises the indications, contraindications, and patient assessment and the surgical procedure, complications ,surgical inter professionalism and future scope of OOKP. The source of data for the review has been Pubmed, Medline and all the research studies and published reports on osteo-odonto-keratoplasty. In this complex procedure good results can be obtained with modern technology and expertise.
