A failed corneal graft as a support for the Boston Keratoprosthesis type 1

The implantation of the Boston Keratoprosthesis (KPro) requires a corneal button, which is usually taken from a donor. Scarcity of donor tissue has been a major limiting factor in transplant surgery. Recently, autologous recipient cornea has been reported as support for the KPro. We report the successful use of an ipsilateral failed corneal graft as the carrier tissue for a patient requiring combined pars plana vitrectomy and KPro implantation.
