PROKERA

Healing Vision. Restoring Life.

Early intervention is critical in eye care. Prokera corneal bandages are designed for treating damaged cornea(s) by creating an environment for regenerative healing.

They are easy-to-use and can be inserted in the office by a trained eye care professional. Because Prokera contains cryopreserved amniotic membrane tissue to promote healing, it excels at restoring a normal and healthy epithelium while minimizing the risk of scar tissue formation. Early intervention with Prokera supports the restoration of the cornea’s own healing capabilities, reducing inflammation, improving corneal health, and optimizing long-term outcomes.

Seeing A Difference

Prokera is the only FDA-cleared cryopreserved amniotic membrane product. It supports the corneal healing process without harmful side effects. Our proprietary CryoTek preservation method maintains full biologic components including a key protein complex HC-HA/PTX3, and structural integrity equivalent to fresh tissue, which helps rapidly restore the cornea’s own healing capabilities.

Alternative amniotic membrane solutions that are dehydrated lack crucial biologic components, which risks repeated epithelial defects or erosions, chronic inflammation, scarring, vision loss, or pain.

The Challenge With

Conventional Treatments

Image

Corticosteroids

Increased ocular pressure, cataract formation, and infection risk
Image

Eye Drops

Ocular surface changes, inflammation, and fibrosis. May rely on a single molecule to address inflammation in multi-factorial diseases
Image

Bandage Contact Lenses

No therapeutic benefits, relies on body’s ability to heal itself

Proven Outcomes

  • Improves corneal nerve regeneration and accelerates ocular-surface health recovery
  • Shown to significantly improve both corneal nerve density and sensitivity
  • Halts fibrosis, facilitating faster re-epithelialization
  • Superior outcomes vs bandage contact lens
  1. — 70% of eyes re-epithelialized by day 5 with Prokera Slim vs. only 20% with bandage contact lens
  2. — 90% of eyes achieved absolute corneal clarity by Day 7 with Prokera Slim vs. 0% with bandage contact lens

The Right Healing.

The Right Product.

We are in a race against time to heal chronic wounds. BioTissue products provide the natural healing properties of human birth tissue to the wound. The BioTissue proprietary CryoTek cryopreservation process is the only tissue processing method shown to produce an allograft comparable to the native tissue.

Prokera® Classic

Maintain orbital space with a symblephoron ring for cases where prevention of closure or adhesion is a concern.
Image

Prokera Slim

Use our ComfortRing™ technology for a lower profile device that contours to the ocular surface to maintain comfort in treatment
Image

Prokera Plus

Maximize the therapeutic benefit with a double layer of cryopreserved amniotic membrane tissue, for patients who need intensive treatment
Image

Prokera Clear

Provide your patient with some visual acuity during treatment with a 6mm ClearView™ aperture. This is crucial in monocular needs
