(a) Kaplan–Meier estimation of graft survival in homologous limbo-keratoplasty for complete limbal stem cell failure. Eye burns included acid and alkali burns with consecutive damage to the limbal stem cells; congenital aniridia included eyes with incomplete formation of the iris and additional complete limbal stem cell failure, and inflammatory diseases limbal stem cell failure due to Stevens–Johnson syndrome, Lyell's syndrome, or ocular citatrical pemphigoid. Other indications were diseases with consecutive complete limbal stem cell failure. (b) Kaplan–Meier estimation of graft survival with regard to endothelial rejection. Eye burns included acid and alkali burns with consecutive damage to the limbal stem cells; congenital aniridia included eyes with incomplete formation of the iris and additional complete limbal stem cell failure, and inflammatory diseases limbal stem cell failure due to Stevens–Johnson syndrome, Lyell's syndrome, or ocular citatrical pemphigoid. Other indications were diseases with consecutive complete limbal stem cell failure.
