The Hydrus microstent (Ivantis) is an 8mm long elastic nickel-titanium alloy implant which is inserted into Schlemm's canal through the trabecular meshwork from the inside of the eye during cataract surgery.
While descriptions of surgical management in this text are centred on more common types of glaucoma, such as paediatric, angle closure and laser approaches to management, not to mention how to deal with concurrent cataract extraction in glaucoma filtration surgery, the text does not shy away from discussing more modern techniques such as the minute stent procedure, which aims to increase aqueous outflow at Schlemm's canal in order to reduce intraocular pressure, to cyclodestructive approaches which are reserved for patients who are unresponsive to even surgical methods of glaucoma management.
It can cause disruption to the trabecular meshwork and Schlemm's canal, which can lead to raised IOP.
