Limbal Stem Cell Corneal Transplant
Limbal Stem Cell Corneal 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 chemical burns, Stevens-Johnson syndrome, and severe contact lens over wear may cause persistent non-healing corneal epithelial defects (defect of the cells which normally cover the surface of the cornea)
These defects result from failure of these stem cells to produce sufficient epithelial cells to repopulate the cornea. If untreated, persistent non-healing corneal epithelial defects are vulnerable to infection, which can lead to scarring, perforation, or both.
Under these circumstances, a corneal transplant, which replaces only the central cornea and not the limbus, is insufficient; stem cells are needed to produce new cells that repopulate the cornea, restoring the regenerative capacity of the ocular surface.
Corneal Limbal Stem Cells can be transplanted from the patient’s healthy eye or from a cadaveric donor eye.
At Visionary Ophthalmology, Dr. Martinez has performed many Limbal Stem Cell Corneal Transplantations. Dr. Martinez will determined weather or not you are a candidate for this procedure and will explain the risks, benefits and likelihood of success in your particular situation.
