AM can modulate corneal epithelium healing by promoting re-epithelialization and migration of limbal stem cell while suppressing stromal inflammation, angiogenesis and scarring. This biological substrate maintain epithelial progenitor cells within the limbal stem cell niche and facilitate ocular surface epithelial renewal. It is well accepted that amniotic membrane Transplantation (AMT) as a temporary patch normally dissolves within 2 weeks. Consequent reapplication of membrane is difficult for the patient.
