Follow-up Extension Up to 43 Years of Modified Osteo-Odonto-Keratoprosthesis

The osteo-odonto-keratoprosthesis is a biological corneal prosthesis (KPro), introduced by Strampelli in 1964. It uses an osteodental lamina as a biological haptic derived from an autologous mono-radicular tooth. An acrylic optical cylinder at the center of the lamina replaces the cornea, and the resulting osteo-dentalacrylic lamina is preferably covered by autologous buccal mucosa or, if not available, by skin. In 2005, Falcinelli et al2 proposed several advances to the original surgical technique, the so-called modified osteo-odonto-keratoprosthesis (MOOKP), reporting favorable results in a large cohort of patients who underwent surgery between 1973 and 1999 and followed up to 25 years.2 This study aimed at extending the follow-up of the same cohort of patients, providing further evidence about long-term anatomic and functional outcomes of the MOOKP technique.
