    New glaucoma devices bring new dimension of treatment


    New World Medical is using research and marketing expertise gained with its Ahmed Glaucoma Valve to develop a novel device to improve outflow by removing a precise strip from the trabecular meshwork.

    The Kahook Dual Blade (KDB), originally developed to harvest cadaver for research by Malik Kahook MD, the Slater Family Endowed Chair in Ophthalmology at the University of Colorado, Denver, uses twin blades to free juxtacaniular trabecular meshwork and open outflow with minimal collateral damage.

    Clinical trials are slated to begin this summer, said Suhali Abdullah, director of research and development at New World Medical. The KDB is covered by existing reimbursement codes and can be used with or without cataract surgery to natural drainage.


    Eye Sonix has more than five years of treatment experience without a single significant  adverse event. That safety record comes with greater than 20% reduction in IOP at 12 months in both naïve eyes and in combination with medication.

    “We have a significant decrease in IOP, which is both sustainable and repeatable,” said Don Schwartz, MD, founder and CEO. “It can be used as an initial treatment or as an adjunct to pharmaceutical agents.”

    The current prototype unit delivers ultrasonic energy to a 1-mm treatment zone that encompasses the trabecular meshwork, open angle, and Schlemm’s canal at 12 locations around the eye. Ultrasound induces hyperthermia and sonomechanical vibrations that loosen blockages in the trabecular meshwork and trigger cytokine cascades to help reduce IOP.


    EyeTechCare delivers ultrasonic energy using a suction cone coupled to the cornea. Energy is delivered to six 1-mm treatment areas around the eye. Ultrasonic energy removes the epithelial layers while preserving the underlying stroma.
