Shares of Glaukos Corporation (NYSE:GKOS), a pioneer of minimally-invasive products and procedures for the treatment of glaucoma, were up in the first quarter due to strong financial results that beat Street expectations, with revenues growing 64%. The company also raised 2017 guidance and announced favorable Medicare reimbursement. Glaukos’ products and procedures are currently approved for only a subset of the market. We believe the company will continue to deliver strong growth as its product coverage broadens. (Josh Riegelhaupt)
