Glaukos will also sponsor an interactive lunch discussion for surgeons, entitled "Transforming Glaucoma Therapy with MIGS Technologies" on March 1, 2018 at 12:15-1:45 EST at the Marriott Marquis, 7^th Floor, Soho Complex Room. Dr. Fechtner will moderate a panel that will include L. Jay Katz, MD; Richard A. Lewis, MD; and Thomas W. Samuelson, MD. Surgeons may register online at https://bmcg.regfox.com/glaukos-ny. In addition, Glaukos will be exhibiting throughout the meeting at Booth #8 on the showroom floor.

Glaukos pioneered MIGS and received U.S. Food & Drug Administration (FDA) approval for the industry's first MIGS device, the iStent^® Trabecular Micro-Bypass Stent, in 2012. Inserted through a small corneal incision made during cataract surgery, the iStent is designed to reduce IOP in mild-to-moderate OAG patients by restoring the natural physiological outflow of aqueous humor through the trabecular meshwork and into Schlemm's canal, the eye's primary drainage channel. Glaukos is currently pursuing FDA approvals for five additional MIGS surgical and sustained pharmaceutical therapy pipeline products:

1. iStent inject^® Trabecular Micro-Bypass System, which is designed for use during cataract surgery and allows a surgeon to inject stents into two trabecular meshwork locations through a single corneal entry point. The iStent inject is approved in the European Union, Armenia, Australia, Brazil, Canada, Hong Kong, Singapore and South America.

2. iStent^® SA Trabecular Micro-Bypass System, which is a standalone, two-stent procedure that is similar to the iStent inject and designed to reduce IOP in pseudophakic, mild-to-moderate OAG eyes.

3. iStent infinite^TM Trabecular Micro-Bypass System, which is a standalone, three-stent procedure, designed to reduce IOP in refractory OAG patients.

4. iStent Supra^® Suprachoroidal Micro-Bypass Stent, which is designed to reduce IOP by accessing the eye's suprachoroidal space and is approved in the European Union.

5. iDose^TM Travoprost, which is an implant containing a special formulation of travoprost, a prostaglandin analog used to reduce IOP. Implanted during a micro-invasive procedure, the iDose Travoprost is designed to continuously elute therapeutic levels of the medication from within the eye for extended periods of time. When depleted, it can be removed and replaced in a similar, subsequent procedure.

About iStent^® Trabecular Micro-Bypass (U.S.)

Indication for Use: The iStent^® Trabecular Micro-Bypass Stent is indicated for use in conjunction with cataract surgery for the reduction of intraocular pressure (IOP) in adult patients with mild-to-moderate OAG currently treated with ocular hypotensive medication.

Contraindications: The iStent^® is contraindicated in eyes with primary or secondary angle closure glaucoma, including neovascular glaucoma, as well as in patients with retrobulbar tumor, thyroid eye disease, Sturge-Weber Syndrome or any other type of condition that may cause elevated episcleral venous pressure.

Warnings: Gonioscopy should be performed prior to surgery to exclude PAS, rubeosis, and other angle abnormalities or conditions that would prohibit adequate visualization of the angle that could lead to improper placement of the stent and pose a hazard. The iStent^® is MR-Conditional, meaning that the device is safe for use in a specified MR environment under specified conditions; please see label for details.

Precautions: The surgeon should monitor the patient postoperatively for proper maintenance of intraocular pressure. The safety and effectiveness of the iStent^® has not been established as an alternative to the primary treatment of glaucoma with medications, in children, in eyes with significant prior trauma, chronic inflammation, or an abnormal anterior segment, in pseudophakic patients with glaucoma, in patients with pseudoexfoliative glaucoma, pigmentary, and uveitic glaucoma, in patients with unmedicated IOP less than 22 mmHg or greater than 36 mmHg after "washout" of medications, or in patients with prior glaucoma surgery of any type including argon laser trabeculoplasty, for implantation of more than a single stent, after complications during cataract surgery, and when implantation has been without concomitant cataract surgery with IOL implantation for visually significant cataract.

Adverse Events: The most common post-operative adverse events reported in the randomized pivotal trial included early post-operative corneal edema (8%), BCVA loss of ≥ 1 line at or after the 3 month visit (7%), posterior capsular opacification (6%), stent obstruction (4%) early post-operative anterior chamber cells (3%), and early post-operative corneal abrasion (3%). Please refer to Directions for Use for additional adverse event information.

Caution: Federal law restricts this device to sale by, or on the order of, a physician. Please reference the Directions for Use labeling for a complete list of contraindications, warnings, precautions, and adverse events.
