  • Research summary

    The objective of this clinical study is to evaluate the safety and effectiveness of subepithelial implantation of the Allotex TransForm corneal allograft (TCA) for improving near vision in presbyopic subjects.
    The Allotex TCA is a piece of acellular cornea, sterilized with electron beam radiation and shaped to a particular shape using a laser. The availability of precise laser shaping systems and sterile corneas are the key factors that make the use of allogenic implants possible. One size of the TCA is available which has a +2.50 D power with a diameter of 2-3.5 mm and a central thickness of 15-25 microns. The TCA is applied to the surface of the cornea at the layer known as Bowman’s membrane, which is just underneath the epithelium.
    The goal is to enhance the visual performance of the patient with a material that is 100% biocompatible and precisely shaped for the individual’s needs.
