What are Amniotic Membranes / Where do They Come From?
An amniotic membrane is part of the fetal placenta. It is the tissue closest to the baby throughout development in the womb. Amniotic membrane protects the baby from any harm and it has natural therapeutic actions which help the baby develop. The placentas used to prepare amniotic membranes are donated by consenting mothers after cesarean section (C-Section) births. Mothers that donate are fully informed, have healthy lifestyles, and are tested against infectious diseases prior to donation.
How does it Work?
Amniotic membranes are rich with fetal stem cells and can function in the eye as a basement membrane substitute or as a temporary graft. It has anti-inflammatory and anti-scarring effects and contains growth factors that promote wound healing on the surface of the eye. The fetal stem cells interact with our cornea's limbal stem cells to enhance their health and promote proper function to enhance healing. Amniotic membrane therapy has been found to be a good alternative for corneal and conjunctival reconstruction in many clinical situations.
