Allergan plc announced the U.S. Food and Drug Administration (FDA) has cleared the XEN® Glaucoma Treatment System (consisting of the XEN45 Gel Stent and the XEN Injector) for use in the U.S. The XEN Glaucoma Treatment System reduces intraocular pressure (IOP) in patients and is indicated for the management of refractory glaucomas, where previous surgical treatment has failed or in patients with primary open angle glaucoma, and pseudoexfoliative or pigmentary glaucoma with open angles that are unresponsive to maximum tolerated medical therapy. XEN is implanted through an ab interno approach and reduces IOP by creating a new drainage channel with a permanent implant that becomes flexible. This provides a new treatment option for the millions of Americans with refractory glaucoma.
