Prokera Amniotic Membrane
What Is Prokera?
Prokera is a sterile, ready-to-use medical device that places a piece of amniotic membrane over your eye to promote natural healing. It provides both physical protection and biological healing, acting as a natural bandage that is easily inserted and removed in your doctor's office.
Amniotic membrane is the inner layer of the placenta, which is donated with consent by mothers after healthy, planned caesarean deliveries. This special tissue has been recognized in medicine for over 100 years for its powerful healing properties. It naturally contains growth factors, proteins, and other substances that calm inflammation, inhibit scarring, and support healthy cell regeneration on the eye’s surface.
The donated amniotic membrane is carefully screened for infectious diseases, sterilized, and cryopreserved to maintain its biological quality. It is then mounted on a small, clear dual-ring system that fits comfortably on your eye. This process preserves all the natural healing benefits while ensuring the device is sterile, safe, and convenient for your eye doctor to apply during a simple office visit.
Unlike artificial bandages or standard eye drops that only provide temporary relief, Prokera uses natural human tissue that works with your body's own healing process. Once placed on your eye, the amniotic membrane releases natural healing factors that reduce pain and swelling while encouraging new, healthy tissue to grow. Acting like a living tissue graft, it helps restore the eye’s natural surface and breaks the cycle of inflammation, making it a much stronger option for stubborn eye problems.
Conditions Treated with Prokera
Prokera can be effective for a broad spectrum of eye surface diseases and injuries, particularly those that are slow to heal or resistant to conventional therapies. It is often recommended for conditions marked by persistent pain, inflammation, or defects on the eye's surface.
For patients with moderate to severe dry eye that doesn't respond to artificial tears or prescription drops, Prokera can help restore the health of the ocular surface. The amniotic membrane reduces inflammation and supports the regeneration of healthy corneal and conjunctival cells, improving both comfort and vision quality.
These are painful open sores or scratches on the cornea that can result from infections, injuries, or contact lens-related problems. Prokera protects the exposed tissue from further damage and accelerates healing, helping prevent complications like corneal thinning or scarring that can threaten vision.
This painful condition occurs when the cornea's outer layer repeatedly tears away, often upon waking. Prokera provides a smooth, supportive surface that allows new cells to adhere properly, strengthening the connection between tissue layers and reducing the frequency of episodes.
Keratitis is inflammation of the cornea, sometimes caused by bacteria, viruses, or contact lens wear. Prokera helps reduce this inflammation and supports tissue repair, often used in conjunction with antimicrobial medications to address the underlying cause and lower the risk of permanent scarring.
When harmful chemicals damage the delicate surface of the eye, Prokera offers an immediate protective barrier. It supplies growth factors and cytokines that help restore normal tissue architecture, potentially avoiding the need for more aggressive surgical intervention.
Severe inflammatory conditions like Stevens-Johnson syndrome or ocular graft-versus-host disease can lead to chronic dry eye, scarring, and even blindness. Prokera is often used to protect the ocular surface, calm inflammation, and support healing as part of a broader treatment plan.
How the Prokera Procedure Works
The Prokera procedure is simple, minimally invasive, and performed right in your eye doctor’s office, usually taking just a few minutes. Most patients experience immediate relief from pain and irritation after placement.
Before the procedure, your eye doctor will apply numbing drops to ensure you are comfortable. They will carefully examine your eye to confirm that Prokera is the right choice for you. You will be advised to stop wearing contact lenses for at least 24 hours before your appointment.
The sterile Prokera device is gently positioned on your eye, much like a large contact lens. The amniotic membrane rests directly against your cornea, while the flexible ring holds it in place without any stitches. The procedure is painless, and you can typically go home right after with clear instructions for care.
While Prokera is in your eye, you may experience blurry vision, a foreign-body sensation, and mild tearing, which are normal and temporary. The amniotic membrane will gradually dissolve over several days, releasing its healing substances directly onto your eye's surface. Your doctor may also prescribe drops to support healing and prevent infection.
Prokera is typically left in place for 3 to 7 days, depending on your specific condition and how your eye is healing. Removal is a quick and painless process performed during a follow-up office visit. Your doctor will then examine your eye to assess the improvement and plan any further care.
Benefits and Potential Risks
Prokera offers many significant advantages for healing the eye's surface, but like any medical treatment, it’s important to understand both its strengths and limitations. This helps you make an informed decision about your eye health.
One of the biggest benefits is faster healing compared to many other treatments, with significant improvement often seen within days. Prokera naturally reduces pain and inflammation, decreasing the need for steroid eye drops or pain medications. By helping to prevent scarring, it can improve long-term vision quality and provide lasting relief from chronic eye surface problems.
The most common side effects are temporary discomfort, like having something in your eye, and blurry vision while the device is in place. Rare complications can include mild irritation, infection, or an allergic reaction to the ring material. These issues are uncommon and typically resolve quickly after the device is removed.
Prokera is generally recommended for adults with moderate to severe eye surface conditions who have not responded well to other treatments like artificial tears or prescription drops. It is not suitable for everyone, including those with certain allergies or active, untreated infections. A thorough evaluation by your eye doctor is crucial to determine if Prokera is a good choice for you.
For many patients, a single Prokera treatment provides lasting relief from symptoms. By reducing chronic inflammation and scarring, Prokera helps preserve the clarity and function of the cornea. Some chronic or severe conditions may require repeat applications to maintain the best results and ensure long-term stability.
Frequently Asked Questions
Patients often have questions about Prokera’s practical aspects, from daily life impacts to long-term outcomes. These answers address key concerns to help you feel more prepared and confident about the treatment.
No, the application uses numbing drops, so you won’t feel pain during insertion. Most patients describe any initial sensation as mild, like wearing a new contact lens, which usually eases quickly as your eye adjusts. As an eye doctor, I recommend reporting any persistent discomfort immediately to ensure a proper fit.
Healing often begins within days, with noticeable improvement in symptoms like pain and redness after removal. Full recovery can take one to four weeks depending on the severity of the underlying condition. Following your aftercare instructions carefully is key to optimizing the healing process.
Driving is not recommended immediately after application or while Prokera is in place due to temporary blurriness that affects depth perception and safety. Vision usually clears within hours to a day after removal, but I advise arranging transportation and testing your sight in a safe space before resuming driving.
Coverage varies by plan and diagnosis, but many insurers approve it for medically necessary cases like severe dry eye or corneal ulcers, often reimbursing a significant portion of the cost. The total cost can range from 500 to 1500 dollars per eye. As a specialist, I help patients navigate pre-authorization to maximize benefits and explore assistance programs if needed.
Your vision will remain blurry while the device is in place because the membrane and ring obscure the cornea, making activities like reading or screen time challenging. This effect is temporary and resolves quickly after removal as the eye heals, often leading to sharper vision overall. Using audio alternatives for essential tasks can help during this time.
Success rates are high, with studies showing 70 to 90 percent of patients experiencing significant improvement in conditions like dry eye or corneal ulcers. Outcomes depend on early intervention and the specific disorder. While not a cure-all, Prokera often reduces the need for more invasive treatments and improves quality of life.
Alternatives are available, and their effectiveness depends on your specific condition.
- Scleral lenses provide a protective tear reservoir but lack Prokera’s anti-inflammatory properties.
- Autologous serum drops use your own blood-derived growth factors for customized relief but require special processing.
- Bandage contact lenses can be used for milder cases but offer less therapeutic benefit.
- In advanced cases, more invasive surgical options like tarsorrhaphy (partially sewing the eyelid shut) may be considered.
After removal, it is important to use prescribed lubricating drops frequently to maintain moisture, avoid irritants like dust and smoke, and attend all follow-up visits to monitor healing. Gentle eyelid hygiene and wearing protective eyewear outdoors also support recovery. This regimen helps sustain Prokera’s benefits and promotes long-term eye comfort.
No, you should not wear contact lenses while Prokera is in your eye. The device itself covers your cornea, and wearing an additional lens could cause irritation, interfere with healing, or damage the amniotic membrane. Your doctor will tell you when it is safe to resume wearing contacts after the treatment is complete.
Yes, for severe or recurrent conditions, some patients may need more than one Prokera treatment. Repeat applications are safe and can be easily performed in the office if your eye doctor determines that an additional treatment would be helpful for your long-term eye health.
No, Prokera is a temporary, biologic bandage that helps heal your existing eye surface. A corneal transplant is a major surgery that permanently replaces part or all of your damaged cornea with donor tissue. Prokera is far less invasive and is often used to help patients heal and potentially avoid the need for transplant surgery.
Prokera is an excellent treatment for the surface of the eye, but it may be combined with other therapies for the best long-term results. You may still need to use lubricating drops, prescription medications, or other treatments specific to your underlying condition as part of a complete care plan created by your doctor.
