Avedro, Inc. Information Request Form

Levi & Korsinsky, LLP has commenced an investigation into the fairness of the sale of Avedro, Inc. (“Avedro” or the “Company”) (NASDAQGM: AVDR) to Glaukos Corporation (“Glaukos”) (NYSE: GKOS). Under the terms of the deal, for each share of Avedro common stock they own, Avedro shareholders will receive an exchange ratio equivalent of 0.365 shares of Glaukos stock.

The Avedro merger investigation concerns whether the Board of Avedro breached their fiduciary duties to stockholders by failing to adequately shop the Company before agreeing to enter into this transaction, and whether Glaukos is underpaying for Avedro shares, thus unlawfully harming Avedro shareholders.

To receive more information, please fill out the form.
