iStent available for glaucoma patients

Last year, the FDA approved the iStent for treatment of open-angle glaucoma, which is the most common form of glaucoma. Open-glaucoma develops when the travecular meshwork within the eye becomes blocked or drains too slowly. This causes pressure to build up in the eye, which can then damage the optic nerve. The iStent is a tiny tube that is only one millimeter in size that is inserted into the eye during cataract surgery. The device is the smallest device ever approved by the FDA and is so small that patients won't feel or see it. The iStent works by draining fluid from the eye. The current methods of treating open-angle glaucoma involve the use of prescription eye drops that usually have to be administered several times throughout the day. The iStent adds to the option that patients have in reducing or eliminating eyedrop therapy.
