Vision Share Spotlights Moria's XTRA4: A Breakthrough in Corneal Preservation and Global Impact

CHICAGO - Oct. 9, 2025 - PRLog -- Vision Share, the largest non-profit network of EBAA accredited and FDA registered eye banks, recently sat down with Jana Tothova, Group Head of Research and Development and Elisa Valguarnera, Product Manager at Moria Surgical to discuss the company's newly FDA-cleared XTRA4™ corneal storage medium - a next-generation solution designed to extend corneal preservation and optimize tissue quality for transplantation.

"The formulation of XTRA4 reflects a deep understanding of corneal physiology," said Jana Tothova, PhD, Group Head of R&D at Moria Surgical. "By replacing dextran and rebalancing the medium, we've created an environment that keeps the cornea in a more natural state —reducing cell stress and maintaining viability and clarity over time."

Developed over years of dedicated research, XTRA4 replaces dextran with a different deswelling agent that better replicates physiological conditions within the cornea. This innovation allows for up to 14 days of storage at 2–8°C, maintaining tissue transparency and endothelial integrity while doubling the traditional preservation window. The FDA's recent 510(k) clearance marks a key milestone for U.S. eye banks and surgeons eager to access extended-life, high-quality tissue.

As an advocate for innovation in eye banking, Vision Share is spotlighting the XTRA4 development to advance conversations among clinicians, researchers, and partner eye banks worldwide. The organization continues to highlight technologies and collaborations that improve patient outcomes and expand equitable access to sight-restoring care.
