What it is
Amniotic membrane is the thin inner layer of the placenta, which surrounds a baby during pregnancy. Tissue is donated, typically after a planned birth, then screened, processed and preserved. Cryopreservation means the tissue is kept frozen so it can be stored until it is needed.
In eye care, cryopreserved amniotic membrane is usually discussed as a thin tissue that a clinician places on the eye's surface, sometimes held in place by a ring or a contact-lens-style carrier. Some products are instead made as drops or liquid preparations. These are different product types, and they should not be treated as interchangeable.
Regulatory status matters here. Some amniotic membrane products are regulated as human tissue products, which is a different pathway from a drug. Most amniotic-derived eye drops and serums are not FDA-approved as drugs. Processing methods vary, and most processed amniotic tissue products contain no living stem cells, so they are not stem-cell treatments. A licensed eye doctor can explain how a specific product is classified.
How it’s traditionally been approached
Amniotic membrane has been used in eye care settings for a long time, most often in office or surgical contexts for the surface of the eye. It has been discussed in connection with a range of ocular surface concerns, and the choice of approach has typically depended on the individual's eye and the clinician's judgment.
People with dry eye symptoms have traditionally started with more familiar steps, such as lubricating drops, lifestyle and environment adjustments, and evaluation of the eyelids and tear film. Other options, including prescription drops and in-office procedures, are discussed by clinicians based on an exam.
Cryopreserved products are only one category within a larger field. Others include dehydrated amniotic membranes, amniotic drops and autologous serum tears. Autologous serum tears are compounded by a pharmacy from the patient's own blood and are not an FDA-approved drug. Each category differs in source, handling and regulation.
How the right eye doctor may help
A licensed eye doctor may help by examining the surface of your eye, reviewing your symptoms and history, and discussing whether an amniotic product is relevant at all. Many people find that a visit also helps clarify what is causing discomfort, since several different conditions can feel alike.
A visit generally includes questions about your symptoms, medications, contact lens use and past eye care, followed by an exam of the eye surface and tear film. If a cryopreserved amniotic membrane is discussed, the doctor can explain what the process would involve, what is known and not known, and what alternatives exist. Only a licensed clinician decides what is appropriate for you after an evaluation.
Good questions to bring: What is the specific product, and where does the tissue come from? How is it processed and stored? What is its FDA or regulatory status? Who performs the placement and where? What is the total cost, including visits and follow-up, and is any of it covered by insurance? What signs should prompt me to call you right away?
The whole-person view
Eyes, body and mind affect one another. Ongoing eye discomfort can be tiring and stressful, and stress, poor sleep and tension may in turn make symptoms feel more intense. Looking at the whole person, including screen habits, rest and daily stress, can be a helpful part of the conversation with your care team.
Some people find body-based support, such as the approaches offered through Somatic Experiences, useful for working with stress held in the body. Others prefer talk therapy, such as through Therapists.plus. These are complementary options for overall well-being and do not replace an eye doctor's evaluation.
Keep in mind
- Cryopreserved amniotic membrane products vary, and not all are regulated the same way; ask a provider about the specific product's FDA or regulatory status.
- Only a licensed eye doctor can decide what is appropriate for you after an evaluation, and no product is guaranteed to work.
- Sudden vision changes, severe eye pain, or an eye injury need prompt professional care; in an emergency call 911.
- If eye problems are weighing on your mental health and you are in crisis, call or text 988.

Frequently asked questions
What is a cryopreserved amniotic membrane for the eye?
It is donated amniotic tissue that has been processed and preserved by freezing for use on the eye's surface. A clinician typically places it during an office or surgical visit. Whether it is relevant to you is something only a licensed eye doctor can determine.
Is cryopreserved amniotic membrane FDA-approved?
It depends on the product type. Some amniotic membrane devices are regulated as human tissue products, which is a different pathway from drug approval. Most amniotic-derived eye drops and serums are not FDA-approved as drugs, so ask your provider about the exact product.
Is amniotic membrane a stem-cell treatment?
No. Most processed amniotic tissue products contain no living stem cells after processing. They should not be described as stem-cell treatments.
Can cryopreserved amniotic membrane help with dry eye treatment?
A licensed eye doctor may discuss it as one possibility after examining your eyes, but results are never guaranteed. Many people begin dry eye treatment with more familiar options, and a provider can explain which approaches fit your situation.
How is it different from autologous serum tears?
Autologous serum tears are compounded by a pharmacy from your own blood, while amniotic products come from donated tissue. Autologous serum tears are not an FDA-approved drug. The two differ in source, processing and regulation.
What should I ask my eye doctor before using an amniotic product?
Ask about the specific product, where the tissue comes from, how it is processed, and its FDA or regulatory status. Also ask about the total cost, follow-up visits, risks and alternatives. A licensed eye doctor's evaluation should come before any use.
