Amniotic membranes are used like biological bandages. These are either cryopreserved (frozen) or dehydrated membranes made from the innermost layer of the placenta. The tissue is collected during planned C-section births from consenting mothers. Donors are screened for communicable diseases, and the tissue is treated with broad-spectrum antibiotics after collection. Amniotic membranes have the ability to promote corneal healing, while also having anti-inflammatory and anti-scarring properties.
