The Express is a glaucoma filtration device that is designed to reduce intra-ocular pressure in patients where medication and other medical procedures haven’t had the desired outcome.

The device creates a subconjunctival filtration bleb, by re-directing aqueous humor (the fluid that fills the space between the cornea and the iris) through a tubular space to a half thickness scleral flap.

This method creates unvarying filtration which helps to stabilize the intra-ocular pressure, and minimize damage to the optic nerve.
