For patients with severe cornea and ocular surface disease, where the stem cells are also damaged, a new technique making use of stem cells of the eye offers new hope to these patients.
Stem cells may be taken from the limbus (the edge of the cornea), the conjunctiva (the membrane surrounding the white part of the eye) and more recently the oral mucosa (the inner lining of the mouth).
These have helped to restore sight to patients who have been blind and where standard treatment has failed.
Dr. Leonard Ang has pioneered some of the latest techniques in stem cell transplant for the eye. His team is the first in the world to carry out conjunctival stem cell transplantation and oral stem cell transplantation for various cornea and ocular surface diseases.
