Corneal Limbal Stem Cell Transplantation
Corneal limbal stem cell transplantation surgically replaces critical stem cells at the limbus (the area where the conjunctiva meets the cornea). Host stem cells normally reside in this area. Transplantation is done when the host stem cells have been too severely damaged to recover from disease or injury. Conditions such as severe Ocular Burns , Corneal limbal stem cells can be transplanted from the patient’s own healthy eye or from a cadaveric donor eye. The patient’s damaged corneal epithelial stem cells are removed by a partial-thickness dissection of the limbus (ie, all the epithelium and the superficial stroma of the limbus). Donor limbal tissue, which is prepared by a similar dissection, is sutured into the prepared bed. Systemic immunosuppression is required after cadaveric limbal grafts.
