SAN CLEMENTE, Calif.–(BUSINESS WIRE)–Glaukos Corporation (NYSE: GKOS), an ophthalmic medical technology and pharmaceutical company focused on novel therapies for the treatment of glaucoma, corneal disorders and retinal diseases, announced today that it has entered into a settlement agreement with Ivantis, Inc. agreeing to terminate the patent infringement lawsuit Glaukos initiated on April 14, 2018 in the U.S. District Court for the Central District of California, Southern Division, concerning Ivantis’ Hydrus^® Microstent.

Under the agreement, Ivantis will pay Glaukos $60 million, $30 million of which will be paid by December 31, 2021, and the other $30 million to be paid by December 31, 2022.
