A medical lens used to treat cornea diseases
Prokera is a medical contact lens.
Prokera lenses are placed in the eye by an eye care professional.
This article discusses how Prokera lenses work and what conditions they help treat.

It also covers how these lenses are inserted and what to expect in terms of outcomes and recovery.
The amniotic membrane contains tissues with biochemical healing properties used in various surgical subspecialties.
The amniotic tissue is taken from healthy, consenting females with no communicable diseases after a C-section delivery.
The tissue is fully screened and tested for transmissible diseases, and it’s treated with antibiotics after collection.
A Prokera contact lens is larger than a typical contact lens.
What Is the Cornea?
The cornea is the clear part that sits over the front of the eye.
It bends light that enters the eye so that you’re able to see clearly.
They also reduce scarring and decrease inflammation.
Prokera may also have antibacterial properties to reduce the chance of infection.
Your vision will be cloudy while being treated with Prokera.
The insertion procedure is fairly simple.
You’ll be seated in the eye examination chair with your head against the backrest.
You may be tilted back in the chair.
Your ophthalmologist or optometrist will rinse the Prokera lens with saline before putting it in the eye.
They’ll apply topical anesthesia, or numbing drops, on your eye to ease any discomfort.
Usually, Prokera is inserted similarly to a regular contact lens.
The outside rings of the lens are thicker and sometimes cause discomfort.
If the lens is very uncomfortable, the medical professional may partially terminate the eyelid with medical tape.
Outcomes
Your eye practitioner can help guide you on what to expect after your treatment.
Your outcome may vary depending on the bang out and severity of your eye condition.
A 2013 study looked at success rates for Prokera for various eye conditions.
For patients with corneal ulcers from infection, 44% showed improvement with Prokera.
Researchers found higher rates of success in patients with chemical injury, with 80% showing improvement.
Researchers also noted that the treatment was well-tolerated and easy for participants to use.
An AMT involves surgically attaching a piece of amniotic membrane to the eye’s surface.
They also noted that Prokera was a more cost-effective treatment.
It protects the eye tissue, stimulates new cell growth, and helps with healing.
Prokera contains a piece of amniotic membrane, which comes from a human placenta.
The amniotic membrane has chemical properties that can help eye conditions heal faster.
Your eye practitioner will insert Prokera lenses in their office or a hospital setting.
