iStent works like the stents used to prevent heart attacks and strokes. When blood vessels get clogged, a stent creates access to the vessel flow. A highly innovative technology, this is how iStent works:
If you have glaucoma, over time the eye’s natural drainage system becomes clogged and iStent creates a permanent opening through the blockage to improve the eye’s natural outflow. Restoring this mechanism lowers and controls pressure within the eye.
iStent is implanted during your cataract surgery procedure. Once implanted, iStent will begin working to safely and effectively manage pressure. What’s more, patients who receive iStent may experience a reduction in glaucoma medications.”
