> In recent decades multiple synthetic corneas have been pioneered and developed, though only three are principally used in practice: the Boston Keratoprosthesis (Massachusetts Eye & Ear Infirmary, Boston, MA), the AlphaCor (Addition Technology Inc., Des Plaines, IL) and the osteo-odonto keratoprosthesis also known as the ‘OOKP’ (originally described by Strampelli, modified by Falcinelli).
