WASHINGTON — Patients with mild to severe open-angle glaucoma who underwent cataract surgery and received an iStent experienced a 33% reduction in medication use and a clinically significant reduction in IOP at 5 years postop, according to a speaker here.
“The IOP reduction and, to a little lesser degree, the medication reduction is sustained at 5 years postoperatively. A higher preoperative IOP is associated with a higher reduction of IOP,” John P. Berdahl, MD, said at the American Society of Cataract and Refractive Surgery annual meeting.
