Amniotic Membranes and Their Magical Healing Properties!

Focal Pointe Eye Care

Amniotic membranes provide super healing properties to the eye. These innovative techniques have given a new outlook on how to manage challenging cases. For over a century, they have been used to heal ulcers, burns, skin grafts, orthopedic pain, and more. Recently optometrists have adopted their use to restore the ocular surface. Corneal abrasions and recurrent corneal erosions benefit significantly from the use of the amniotic tissue. Another use which has gained more traction in optometry is for healing Neurotrophic Keratitis (NK) in Dry Eye Disease (DED).  Learn more about NK from our blog.

The amniotic tissue is composed of several characteristics that promote wound healing and growth. Membranes are collected from the innermost layer of the placenta during healthy, voluntary cesarean sections. The donors and membranes are screened for transmissible diseases, and tissues are treated with antibiotics after removal.

For optometric use, the membranes are encased in a ring to be placed in the eye, similar to a contact lens. The 3 different layers of the tissue closely mimic that of the cornea, which makes it a perfect choice in healing the eye. The amniotic tissue itself acts as a “bandage” to protect the ocular surface as it is healing. The basement membrane layer promotes tissue growth and prevents cell death. The stromal layer prevents scarring and reduces inflammation. Other properties include antimicrobial benefits, prevention of new blood vessel growth, and promotes nerve regeneration- amazing news for treating NK!

 

To receive maximum healing benefits, the amniotic membrane only needs to remain in place on the eye for about 24-48 hours. Typically, the eye will be taped while the lens is in place to allow it to settle. Prescription drops can be used while the lens is in place. Most patients can find the lens a bit uncomfortable, but the long-term benefits outweigh the short-term inconvenience. If both eyes need treatment, amniotic membranes are placed one at a time. Benefits from amnion placement can last up to 6 months!
