    Microstent approval makes big news in glaucoma world

     

    “Implanted using a non-perforating ab interno approach, this device is placed at the base of the scleral spur and slides nicely into the subconjunctival space,”  said Steven D. Vold, MD. “For surgeons...who have not done a lot of angle surgery, the CyPass might be a good alternative.”

    Dr. Vold, who is in private practice in Fayetteville, AR, is a consultant to Transcend Medical and Alcon Laboratories.

    Contraindications

    The device is contraindicated in eyes with angle closure glaucoma and eyes with traumatic, malignant, uveitis, neovascular glaucoma, and eyes with discernible congenital anomalies of the anterior chamber angle.   

    The randomized clinical trial compared patients with cataract surgery paired with the device to patients in a cataract surgery group.
