Description

AlphaCor is a biocompatible, flexible, one-piece artificial cornea (keratoprosthesis) designed to replace a scarred or diseased native cornea.

The World Health Organisation (WHO) reports that corneal blindness affects more than 10 million people worldwide, however only 100,000 people receive corneal transplants each year. This shortfall is due to a combination of inadequate supply of donor corneas and the unsuitability of some patients to receive a corneal graft.

AlphaCor is designed for use in patients who have had multiple failed corneal transplants or in those patients in whom a donor graft is likely to fail.

Its patented design features are aimed to promote retention, minimize post-operative complications and restore vision in patients who cannot receive, or are unlikely to have a beneficial outcome from, a human donor graft.

AlphaCor is available in two versions, to suit those with a natural lens (phakic) or artificial lens (pseudophakic) and for those without a lens (aphakic).

  • FeaturesDesign:
    AlphaCor is a one piece convex disc consisting of a central transparent optic and an outer skirt that is entirely manufactured from poly (2 – hydroxyethyl methacrylate) or PHEMA. AlphaCor’s material and patented features are designed to promote retention and optimize patient outcomes.

    Outer Skirt:
    The outer skirt is an opaque, high water content, PHEMA sponge. The porosity of the sponge encourages biointegration with host tissue and thus promotes retention of the implanted device.

    Central Optic:
    The central optic core is a transparent PHEMA gel providing a refractive power similar to that of the human cornea. The optic core is designed to allow the patients’ visual potential to be achieved.

    The Interpenetrating Polymer Network (IPN):
    The junctional zone between the skirt and central optic is the Interpenetrating Polymer Network or IPN. This is a permanent bond formed at the molecular level and is designed to prevent the down-growth of cells around the optic, which can lead to the formation of retroprosthetic membranes, one of the major complications historically associated with artificial corneas.
