Transplantation of Limbal Stem Cells

Corneal transplant surgery

Corneal disease is one of the major causes of blindness worldwide. Removal of the damaged cornea and transplant of donated tissue is often the only option available to patients to improve and restore vision. This paper discusses corneal transplant with consideration given to penetrating keratoplasty (PK), a traditional full thickness corneal transplant and three other surgical techniques that offer an alternative to the traditional PK surgery: deep anterior lamellar keratoplasty (DALK), deep lamellar endothelial keratoplasty (DLEK) and limbal stem cell transplant.
