Focus on MIGS

New tools for micro-invasive glaucoma surgery

Glaucoma treatment is advancing rapidly, with new less invasive tools & devices improving patient outcomes. One such device is the Transcend Medical CyPass Micro-Stent. Designed to be implanted at the time of cataract surgery, the stent reduces intraocular pressure (IOP) in patients with primary open-angle glaucoma by enhancing suprachoroidal aqueous outflow. Dr. Steven D. Vold has been participating in clinical trials of this soon-to-be released device over the last 2 years. In the latest EyetubeTV – AECOS Summer Symposium 2015 video, Dr. Vold discusses his initial findings with moderator Dr. Mark Kontos.

“We’re looking at 30-40% IOP lowering, we also are getting most of our patients off all of their drops,” Dr. Vold explains in the video. “So, for people with mild to moderate glaucoma in the setting of cataract surgery, I can tell you right now number one it’s efficacious; having now over 5 years of experience of this device, we’re talking about long term efficacy.”

As Dr. Vold explains, the CyPass is approaching FDA approval, with the hope that it will be brought to market shortly. At this time, the leading MIGS device on the market is the Glaukos iStent Trabecular Micro-Bypass, which has also been shown to reduce IOP and reduce patient dependence on medication (source:

The use of either device in MIGS procedures is complemented by the use of Volk’s TVG Surgical Gonio lens. The result of a design collaboration between Dr. Vold and Transcend Medical, manufactured by Volk, the TVG was designed specifically for precision and comfort in MIGS and all intraoperative gonioscopy procedures. Its floating lens eliminates corneal pressure and the resulting distortion of chamber angle view for optimal stent placement.
