Video transcript:
The Hydrus microstent is made from nitinol, a titanium alloy used in cardiac stents that has excellent biocompatability with the body and eye. It is a tiny, flexible device curved to follow the contour of Schlemm's canal, the natural drainage channel of the eye. It has a fluid inlet at one end, a smooth tip at the other, and three windows along it's length. At 8mm long and just 310um in diameter, it is often compared to the size of an eyelash. The Hydrus microstent is precisely implanted into Schlemm's canal, which is located near the base of the iris. It acts as a scaffold, dilating open Schlemm's canal and allowing fluid to flow freely into it. The Hydrus stents open 90 degrees of the canal, giving the aqueous humour enhanced access to a number of downstream collector channels. The result is that fluid can drain from the eye more easily, allowing intraocular pressure to fall. I published a detailed review of these drainage pathways, and how they can be enhanced using micro-invasive glaucoma surgery, in Survey of Ophthalmology, the flagship review journal for Ophthalmology. The Hydrus microstent remains in the eye for life and is neither seen nor felt by the patient.
