The scenario
The global demand for corneal transplants continues to rise, yet the technology to preserve donor tissue has remained largely unchanged for decades.
XTRA4™ represents a breakthrough in hypothermic corneal storage—a dextran-free, science-driven formulation that maintains corneal thickness, preserves endothelial integrity, and integrates seamlessly into existing eye bank protocols.
