Dr. Brad A. Snead of Snead Eye Group has recently received certification to provide iStent Trabecular Micro-Bypass Stent to treat cataracts and glaucoma. Glaucoma affects over 60 million people worldwide and is the second leading cause of irreversible blindness. The disease is defined by pressure inside the eye, cupping of the optic disc and loss of visual field. Glaucoma can not be cured and treatments aim to reduce the pressure within the eye, which is normally achieved through medical therapy, laser treatments or incisional glaucoma surgery. Because of the risk of severe side effects, surgery was usually reserved for advanced stages of the glaucoma, when topical antiglaucoma drugs and laser treatments fail to control the disease.
