Minimally invasive, maximally effective

Behind the apparent simplicity of ABiC™ and Canaloplasty is the iTrack™ surgical system. Intelligently designed and meticulously tested across each treatment step, the iTrack™ surgical system comprises the iTrack™ microcatheter, the ViscoInjector™ viscoelastic injector, and the iLumin™ illumination source.

Unique illumination

Featuring a unique, proprietary illuminated tip, you can monitor progress of the iTrack™ microcatheter through every procedural step. iTrack's tip is also lubricious and atraumatic, which means that ease of insertion is enhanced, and direction accuracy is maximized to prevent the catheter broaching the collector channel ostia.

An internal guide wire within iTrack™ provides excellent tactile feedback as the tip is advanced, offering a vital insight on whether the canal is tight, grainy, or completely open.

Precise viscodilation

The ViscoInjector™, which attaches to the iTrack™ microcatheter, is manually operated using a tactile and audible knob to release a precisely measured aliquot of viscoelastic per click. 

The delivery of viscoelastic during the withdrawal of iTrack™ from Schlemm’s canal accomplishes a vital additional function that complements the mechanical opening achieved with the iTrack™ microcatheter; it separates the compressed tissue planes of the trabecular meshwork, causing any herniated inner wall tissue to withdraw from the collector channels.

A restorative approach with ABiC™

ABiC™ is a comprehensive minimally invasive glaucoma surgery procedure that flushes out the natural outflow channels without damaging tissue, and without leaving behind a stent or shunt. Designed to re-establish the eye’s natural outflow drainage system, ABiC™ accesses, catheterizes, and viscodilates the trabecular meshwork, Schlemm’s canal, and also the distal outflow system— maximizing efficacy and minimizing tissue trauma. On average, ABiC™ performed with the iTrack™ surgical system achieves a reduction in mean IOP of 30%, combined with a 50% reduction in medication dependence.1

    Less risk, less discomfort with Canaloplasty

    Clinical studies show that Canaloplasty performed with the iTrack™ surgical system reduces IOP significantly and durably — without the risks and discomfort associated with trabeculectomy. This means that the treatment can be offered earlier in the disease. 

    In addition, Canaloplasty doesn’t produce a filtering bleb, and hence patients can resume day-to-day activities directly following treatment with minimal follow-up required.

    “The success of ABiC, which requires threading of the iTrack catheter through the canal with micro-forceps, relies on the ability to receive real-time, tactile feedback of the health and patency of the canal. The iTrack provides this feedback. It also features a small gauge support wire, which provides enough strength to allow you to bypass tight areas within the canal. This, coupled with focal viscodilation, enables you to pass the iTrack beyond adhesions or other canal abnormalities.”

    iTrack™ Microcatheter

    Illuminated fiber optic tip provides continuous location feedback, eliminating misdirection into a suprachoroidal drainage system or the collector channel ostia.



    Internal guide wire enables you to push through herniations and to maneuver through tight areas or structures of the canal, without the risk of creating an artificial pathway.



    ViscoInjector™ Viscoelastic Injector

    Sophisticated injector releases a precise dose of viscoelastic to balloon open the canal and the collector channel ostia.
