Cryopreserved amniotic membrane (AMNIOGRAFT) is the only amniotic membrane tissue that aids in ocular surface wound repair and wound healing. The natural properties of the tissue have been proven to reduce scarring, reduce abnormal blood vessel formation, reduce pain and aid in healing. When AMNIOGRAFT is used in pterygium surgery, patients have less pain and an improved cosmetic outcome when compared to patients treated with other pterygium excision procedures.
