With its DMEK instruments German Geuder AG offers an innovative solution for the therapy of endothelial corneal diseases. Heart of the DMEK instruments is the DMEK implantation cartridge developed by Prof. Dr. med. Peter Szurman at Knappschaft-Augenklinik Sulzbach, Germany. This cartridge ensures a contactless and atraumatic intake of the fragile descemet lamella by smooth aspiration and, thanks to the streamlined design and the embedding in liquid, a gentle injection into the anterior chamber of the patient´s eye. Another advantage derives from the high transparency of the glass cartridge, which allows a controlled positioning of the descemet lamella already during the injection.

As a complement to the already successfully applied and reliable cartridge, GEUDER enables a 20% smaller incision with the next cartridge generation. That way the risk of a surgically induced astigmatism is further reduced. Surgeons can make a case-specific decision about the suited version.

  • No Touch

    • Contactless intake of the graft into the cartridge by smooth aspiration. Gentle injection into the anterior chamber
    • Reduced risk of damage to the fragile graft and less endothelial cell loss

  • No Friction

    • Embedding into liquid allows a smooth sliding of the graft into the anterior chamber
    • Safe flow of the graft through the streamlined design of the glass cartridge

  • No Suture

    • Minimum incision size (2.4 to 2.75 mm) thanks to the more slender opening of the new cartridge generation
    • Proven incision size of 3.0 mm for easier handling of “more rigid” donor lamellas

In addition to the sterile implantation cartridge a selection of instruments for the preparation of the donor and recipient eye as well as for the implantation of the graft is available.
