Application Detail

Description of Medical Service

Similarly, to stents placed into Schlemm’s canal, a microcatheter is first inserted into Schlemm’s canal via the trabecular meshwork and circumnavigated 360 within Schlemm’s canal. The microcatheter breaks inner lumen adhesions and opens stenotic areas of the canal. The microcatheter dilates the canal with high molecular weight ocular viscosurgery device fluid (viscodilation) and separates herniations of the trabecular meshwork into the collector channels , thereby reducing intraocular pressure
