When the corneal surface becomes significantly damaged or fails to heal adequately with conventional treatment, your doctor may recommend an amniotic membrane.
Amniotic membrane is obtained from the innermost layer of donated human placental tissue following carefully screened childbirth donations. It has been used in ophthalmic medicine for decades as a biological covering for injured ocular tissues.
Amniotic tissue contains a specialized basement membrane and extracellular matrix that can provide a favorable environment for epithelial healing. Depending upon the clinical situation, amniotic membrane therapy may help protect damaged corneal tissue, support epithelial-cell migration, reduce excessive inflammation, reduce scar-producing processes, improve comfort, and support restoration of a healthier ocular surface.
A Biological Bandage
A traditional bandage contact lens primarily provides mechanical protection.
An amniotic membrane functions differently. It serves as a temporary biological scaffold and protective covering while the ocular surface heals.
The purpose of treatment is not simply to cover the eye, but to create an environment more favorable to recovery of the damaged epithelial surface.
How Long Does an Amniotic Membrane Remain on the Eye?
This depends upon the membrane being used, the severity of the ocular-surface condition, and the patient’s rate of healing.
Some membranes gradually dissolve or are absorbed as the ocular surface heals. Others are removed by the doctor after several days.
Follow-up examinations allow the doctor to evaluate epithelial healing and determine whether additional treatment is necessary.
Insurance Coverage and Medical Necessity: Amniotic membrane treatment may be covered by Medicare or commercial insurance when applicable medical-necessity requirements are satisfied. Coverage varies according to diagnosis, severity of disease, objective clinical findings, previous treatments, individual insurance benefits, and payer policy. Prior authorization or verification of benefits does not guarantee payment. When possible, our office will review applicable benefits and expected patient financial responsibility before treatment.
