Abstract

Amniotic membrane transplantation in these cases offers the following advantages: avoidance of potential allograft rejection and postoperative astigmatism of tectonic corneal grafts, ease and convenience of use, feasibility in the event of corneal tissue shortage, and preservation of a better aesthetic appearance. Even if corneal transplantation is needed, its success is promoted if performed in an eye that received AMT to reduce inflammation. When corneal ulcer is superficial (e.g., limited to the epithelium), AMT using an overlaid graft is generally sufficient. However, when epithelial defects are accompanied by stromal ulceration, a temporary overlaid AM graft is used together with a permanent graft to provide as additional protection while ensuring epithelialization. Amniotic membrane transplantation is performed using standard surgical instruments and microsurgical equipment.
