Research & Development
Prokera is a combination medical device used by eye doctors around the world for anti-inflammation, anti-scarring and promoting healing of damaged eye surfaces. It contains the only FDA-cleared cryopreserved amniotic membrane, which supports the corneal-healing process without harmful side effects.1,2,3
Frequently Asked Questions
What is Prokera?
Prokera is made from amniotic membrane which has natural anti-inflammatory and anti-scarring properties. It is the only FDA-cleared therapeutic device used by eye care practitioners to provide quick1 symptom relief and reduce inflammation associated with ocular surface disease. It helps restore your cornea and return your eye to a normal, healthy state.
What is amniotic membrane tissue?
Amniotic membrane is part of the placenta and is the tissue closest to the baby throughout development in the womb. Amniotic Membrane protects the baby from any harm and has natural biologic actions which help the baby develop. The tissue has biological properties that aid in ocular surface repair.
The amniotic membrane tissue in Prokera has natural therapeutic actions that help damaged eye surfaces heal. Eyes treated with Prokera have less scarring and less inflammation. The amniotic membrane in Prokera is thin and clear like the tissue on the surface of your eye and protects your eye’s damaged tissue while inserted.
What does Prokera treat?
Prokera is used by eye doctors to treat eye diseases such as keratitis, corneal scars, chemical burns, corneal defects, partial limbal stem cell deficiency and many other ocular surface diseases with inflammation.
Prokera is provided by a tissue bank regulated by the FDA. The tissue has passed many quality control tests before it is provided to your doctor. Ask your doctor if you are concerned about the risks involved with using a human tissue.
Is Prokera safe?
Prokera is a safe treatment provided by an FDA-regulated tissue bank. The tissue is donated from healthy mothers who have had c-sections. The donor and tissue have passed numerous quality control tests including social habits, physical and medical screening before it is provided to your doctor.
What should you expect?
Prokera is similar to a large contact lens. You may experience awareness of the ring but it is not painful. For optimal healing, it is important that you complete the Prokera treatment period of 3-5 days. Your eye doctor may use tape to partially close your eyelid after Prokera is inserted.
Special instructions for Prokera:
- Avoid rubbing your eyes, forceful blinking, or moving Prokera with your fingers
- Do not remove Prokera without consulting your eye doctor first
- Do not swim or soak your eye with water
- Shower only when the eye is tightly closed
- Do not drive or operate heavy machinery or perform functions that require unobstructed vision or good depth perception
- Use eye drops and other medications as prescribed by your eye doctor
Contact your eye doctor right away if you are uncomfortable or have any other problems with Prokera, such as swelling, redness or discharge.

Frequently Asked Questions
What is AmnioGraft?
AmnioGraft is the only cryopreserved amniotic membrane tissue that has been recognized by the FDA for its unique anti-scarring, anti-inflammatory and anti-angiogenic properties.
The tissue is donated by healthy consenting mothers after scheduled cesarean section (C-Section) births within the USA. Donor suitability is stringent and is determined through social, physical, and medical screening.
What is amniotic membrane tissue?
Amniotic membrane is part of the placenta. It is the tissue closest to the baby throughout development in the womb. The biological properties of amniotic membrane protects the baby from any harm and its natural therapeutic actions helps the baby develop.
The placentas used to prepare AmnioGraft are donated by consenting mothers after cesarean section births. Mothers that donate are fully informed, have healthy lifestyles, and are tested against infectious diseases prior to donation.
Is AmnioGraft Safe?
AmnioGraft is a safe, effective product provided by a FDA-regulated tissue bank. AmnioGraft has never been associated with any serious adverse events in the last 20 years of widespread clinical use.
AmnioGuard is an ultra-thick amniotic membrane that is thicker and stronger tissue contains amniotic membrane that has been recognized by the FDA for its unique anti-inflammatory, anti-scarring, and anti-angiogenic properties. This tissue is used by eye surgeons around the world to cover the glaucoma shunt tube and to protect, repair, and promote regenerative healing of damaged eye surfaces.

As a sales professional and someone who makes their living interacting with the public, I often had people comment my eyes appeared to be red and tired looking. Finally, I reached a point where it was time to address my problem! After doing some research, I concluded there was an “old way” of performing pterygium surgery, and a “newer, more advanced method” using the AmnioGraft. I decided to go for it. Two years later, I could not be happier! The recovery time and healing process was completely uneventful, and my eyes look great!
AmnioGraft enables me to prevent inflammation, scarring, promote rapid regenerative healing post-operatively, in a manner not achievable with denatured tissue. AmnioGraft also preserves the cellular architecture of the tissue and hence retains intraoperative resilience, workability, and handling – much like an ‘instant pre-packaged autograft’ — allowing for superior, efficient, and reproducible surgical results.
Dr. Sally Mellgren performed the above procedure [AmnioGraft for Mechanical Dry Eye] on my right eye and on my left eye. I experienced no problems with the recovery from the procedures. My vision and clarity was much improved and I would recommend it for others experiencing the same problems.
For many years, I suffered in pain from my dry eyes which eventually led to a corneal ulcer. My eyes were constantly itchy and red and my vision fluctuated. The treatment with Prokera was quick and simple, and felt similar to a contact lens being inserted. My vision has improved, which is crucial to me as an artist. Prokera has truly changed my quality of life and brought me back to feeling normal again.
