Der Zahn im Auge - Die erste in der Schweiz eingebrachte Osteo-Odonto-Keratoprothese

We report on the first implanted Osteo-Odonto-Keratoprosthesis (OOKP) in Switzerland. The procedure is only performed in cases of severe bilateral corneal vision impairment without alternatives (e. g. allogenic corneal transplant). At this two-staged surgery a single-rooted tooth is removed with its belonging bone and an optic cylinder is centrally inserted. This tooth-bone-optic-cylinder-complex is implanted temporarily submuscular in the infraorbital area. Oral mucosa is removed and transplanted on to the eye. Three months later the complex is removed, the oral mucosa partially detached, the underlying cornea perforated, the lens, iris and anterior vitreous body removed and the tooth-optic-zylinder-complex fixated on the globe. After this procedure, our patient has a best corrected visual acuity of 0,7.
