Sterile tissue
halo®
E-beam sterilised cornea, sclera and pericardium for glaucoma and corneal surgery, ready to use from the shelf. From Vision Share, supplied in South Africa by Evolution Vision.
Overview
What halo is
halo is e-beam sterilised cornea, sclera and pericardium, sterilised to a sterility assurance level (SAL) of 10⁻⁶. It is ready to use, with no rinsing or rehydration.
It suits tectonic and reconstructive work, where the tissue has to be on the shelf already.
halo corneas are clear and stay clear, which makes post-operative assessment easier and leaves a better cosmetic result.
