“Dedicated to treating your Dry Eye patients with biological therapies”

The BLOOD PRODUCTS of today ARE the BIOLOGICAL TECHNOLOGIES of tomorrow. Vision Care providers know that the loss of tear production can have severe visual consequences. “Natural tears are made up of key components not found in artificial tear products, such as epidermal growth factor (EGF), transforming growth factor beta (TGF beta), fibronectin and vitamin A; which we believe could support the proliferation, maturation, migration and differentiation of corneal and conjunctival epithelia.” 1 Unlike natural tears, AST provides some of these key components.
