Researchers have demonstrated the long term effectiveness of using stem cells to cure corneal blindness. University of Modena : From 1998 to 2006 the team, Graziella Pellegrini performed 125 stem cell procedures on 112 patients, all who had lost partial or complete vision due to chemical or thermal burns. Stem cells were taken from the limbus in the patient’s own eye, cultured, and then grafted back on the eye. The grafts had a success rate of 76.6% and the positive results have lasted. One patient has been followed for more than 10 years and still has healthy, restored vision.
