A non-bioabsorbable, implantable ocular device intended to create an artificial drainage channel for diversion of aqueous humour from the anterior chamber of the eye to reduce intraocular pressure (IOP) as an alternative to, or after failed, trabeculectomy, for the management of uncontrolled glaucoma. It consists of a tube which is introduced into the aqueous body (typically via limbal entry) and a distal episcleral plate intended to support a reservoir of aqueous humour; the shunt does not contain a valve.
