About shunts

A shunt is, basically, a tube to open a passage somewhere in the body so fluids can move. In glaucoma, various kinds of shunts may be placed in the eye to enable healthy flow of fluid, so IOP is kept low enough. In the best of all worlds, this could mean no more eye drops, at least for some patients.

Various kinds of intraocular shunts have had various downsides, including in some cases repeat surgery, which it's hoped Beacon will not require. A significant difference is that while most shunts move fluid within the body, the Beacon moves aqueous humor out of the eye, to the surface.
