The iStent Trabecular Micro-Bypass Stent System or simply 'iStent' is a miniature device that is designed to minimize the harmful impact of glaucoma, an eye disease that is caused by a buildup of pressure behind the eye. Left untreated, glaucoma can cause blurry vision and even blindness. It affects more than 2.2 million people in the U.S.
The iStent is the smallest device ever approved by the FDA, and is used in conjunction with cataract surgery. It is inserted via a 1.5-millimeter corneal incision and works by opening up blockage to relieve pressure in the eye. It is designed to improve the flow of natural eye fluids in order to lower pressure in the eye, therefore reducing the negative impact of glaucoma.
Technological devices have been commonplace in the medical world for a long time now, but what's truly impressive about the iStent is its compactness and the fact that it's minimally invasive but so effective.
