Patients with dry eye disease may also have corneal damage. The cornea is the clear dome-like structure that sits on the front of the eye. If the cornea becomes damaged, it may lead to discomfort and a worsening of vision. In patients with dry eye disease with accompanied corneal damage, an amniotic membrane may be prescribed.
Just as an amniotic membrane helps protect the womb and the baby during pregnancy, when placed on the front surface of the eye, it prevents scarring and naturally heals the damaged cornea. It can be used for several types of eye conditions, but mostly for corneal disorders and dry eye disease.
