What is an amniotic membrane?
- An amniotic membrane is the inner layer of fetal membrane.
- The membrane has anti-inflammatory, anti-fibrotic, anti-angiogenic and anti-microbial properties.
- An amniotic membrane is a healthy, intact, basal membrane on which the patient’s cells are able to proliferate.
- It returns the ocular surface to healthy level2
What ocular pathologies can amniotic membranes improve?
Who is a good candidate? Who is not a good candidate?
- Any patient who has any of the aforementioned conditions is a potential candidate.
- Patients with mild dry eye who can be treated with standard treatments (Restasis, Lotemax, ATs) are not ideal candidates.2
- Treatment has been less successful in the following conditions:
- mucous membrane pemphigoid (79 percent)
- chronic Stevens-Johnson or Lyell’s syndrome (62 percent)
- reconstruction of the conjunctiva and fornix (47 percent)
- neoplasia of the ocular surface (33 percent)
- primary and secondary limbal stem cell deficiency (32 percent)
- physical trauma (30 percent)
- chemical trauma (24 percent)
- pterygium (8 percent)
- recurrent epithelial erosions (5 percent)3
Patients should be educated on discomfort due to the size of the membrane and blurred vision during the healing process. Patients should also be placed on Restasis and Lotemax TID while the membrane is on the eye. 2
Procedures for Application and Removal
Storage – can be stored in a refrigerator up to 3 months and a freezer up to 1 year.
- Rinse the device with saline when it arrives to prevent burning upon insertion.
- Hold the ring with your thumb and forefinger at the 6 o’clock position.
- Apply topical anesthetic.
- Have the patient look down, and apply the membrane to the superior conjunctival fornix.
- Have the patient look up and apply the membrane to the superior conjunctival fornix.
- Tape the temporal half of the upper eyelid closed to decrease movement and increase comfort.1
- Approved to stay on the eye for a maximum of 8 weeks or until tissued has healed. Healing is usually completed between 1-2 weeks.
- Membrane can be completely absorbed by cornea within 1 week, but plastic ring must be discarded.
- Apply topical anesthetic.
- Have the patient look up and lift the lower edge.
- Apply a gentle pressure to the superior lid in a downward motion.
- Preservative free ATs can be used to improve comfort.1
