San Clemente, Calif.-based Glaukos Corp. has finished enrolling patients in its U.S. investigational device exemption (IDE) trial for the Istent Infinite trabecular micro-bypass system, which is intended for standalone use in lowering intraocular pressure (IOP) in refractory glaucoma patients. If all goes as planned, the company is looking to commercially launch the treatment in the U.S. in 2021.
