  • Research summary

    The purpose of this clinical research investigation is to evaluate the safety and effectiveness of implantation of the Allotex TransForm corneal allograft (TCA) for improving distance vision in hyperopic patients. The expected duration of the clinical investigation is 3 years, subject participation will last 2 years.
    The Allotex TCA is a small piece of sterile human tissue designed to change the shape of the first layer of the eye known as the cornea (which is like the crystal on a watch), to adjust the point of focus of light at the back of your eye. The tissue source is specially treated human corneas from an eye bank in the United States.
    Following topical anesthesia, the surgeon first creates a pancake-like flap of the cornea using a laser. After the flap is created, your surgeon will place the TCA beneath the open flap and then complete the procedure by
    re positioning the corneal flap on the eye. When the flap is replaced, it lies on top of the TCA, causing the surface to change shape which will attempt to improve your distance vision and reduce your dependence on corrective lenses (spectacles and/or contact lenses).
    Up to 121 patients are being included in the clinical investigation.
