Amniotic Membrane
Amniotic membrane, which is obtained from amniotic sac or the water bag that holds the fetus during pregnancy has medicinal values and is used in ocular surgery to help poorly healing tissue obtain the necessary growth factors and/or to prevent regrowth of abnormal tissue (e.g. pterygium). There are a number of commercially available amniotic membranes that are safe and FDA approved for ocular surgery.
