Gold microshunt: The Solx Gold Shunt (Solx), an ab externo suprachoroidal trans-limbal shunt, draining aqueous into the suprachoroidal space. Aqueous flows both, through the channels in the body of the shunt as well as around its body, acting like a controlled cyclodialysis.
Eyepass: This bidirectional shunt also diverts aqueous from the anterior chamber directly into Schlemm’s canal. InnFocus MicroShunt: The InnFocus Microshunt (Santen) is a minimally invasive, plateless glaucoma drainage microshunt made from an inert biomaterial called SIBS (polystyrene-block-isobutylene-block-styrene). The device shunts aqueous humor from the anterior chamber to the sub-Tenon capsular space. The MicroShunt differs from the Xen45 Gel Stent since it is implanted ab externo, requires a conjunctival incision, with potentially more scarring than with the Xen Ab Interno Canaloplasty Using the iTrack 250A Microcatheter, ABiC:ABiC opens up the whole outflow system and viscodilates all sites involved in the control of aqueous
