The device works much like the stents used by cardiologists to maintain blood flow to the heart. It is implanted during cataract surgery and immediately opens the internal aqueous drainage system that is the usual source of increased intraocular pressure in eyes with open-angle glaucoma. The iStent® can’t be felt or even seen (without a microscope and a special lens). It doesn’t wear out or need replacement.
Glaucoma drops can often be reduced or eliminated after iStent® implantation and eye pressure is usually lowered by about 3 mm Hg compared with cataract surgery alone.
Dr. John Parker was one of the first Alabama ophthalmologists trained in iStent® surgery. He implants the device regularly.
