iTrack™ Microcatheter

Featuring a proprietary, patented design, iTrack™ is the only illuminated, micron-scale microcatheter, designed to viscodilate Schlemm’s canal during ABiC (ab-interno canaloplasty). Specifically, the iTrack™ enables surgeons to:

    1. Open a collapsed Schlemm’s canal
    2. Stretch the trabecular plates to allow aqueous into Schlemm’s canal; and
    3. Break adhesions and separate herniations to open the atrophied outflow collector channels

The iTrack™ system comprises the iTrack™ microcatheter, the ViscoInjector™ viscoelastic injector and the iLumin™ illumination source.


  • Illuminated, micron-scale microcatheter.
  • Illuminated tip for transscleral visualization during 360˚ cannulation, allowing surgeon to monitor location of catheter tip at all times.
  • Choice of intermittent “blinking” or “constant” illumination.
  • Small-gauge support wire for greater control during advancement through Schlemm’s canal.
  • Infusion and aspiration lumen for the controlled delivery of viscoelastic.
  • Round, bolus atraumatic tip and lubricious coating for reduced inner lumen trauma to Schlemm’s canal during catheterization.


  • Viscoeslactic injector which attaches to iTrack™ microcatheter.
  • Manually operated for precision delivery of viscoelastic.
  • Tactile and audible knob: clicks every 1/8 turn (as per Canaloplasty protocol); alignment marks to guide priming and use.


  • Portable laser diode illumination source.
  • Proprietary connector for use with iTrack™ microcatheter.

Why Choose iTrack?

Transscleral Visualization
Featuring an illuminated tip, the iTrack™ 250 microcatheter can be continuously monitored once it is inserted into Schlemm’s canal, ensuring it is directed as intended.

360 Degrees, With Ease
The unique design of the iTrack™ includes a rounded, atraumatic tip and a lubricious coating (similar to that used in cardiology). This design aids insertion and helps to prevent the iTrack™ from getting misdirected into the collector channels. A small-gauge wire, which ensures greater control during the procedure, further permits full circumferential viscodilation of the entire length of Schlemm’s canal

Viscoelastic Injection
The iTrack™ 250 microcatheter features a 200-micron diameter shaft that is connected to an ophthalmic viscosurgical device (OVD) injector, which permits precise injection of viscoelastic during cannulation.

ABiC: A New Comprehensive MIGS

Performed as a stand-alone procedure or as an adjunct to cataract surgery, ABiC™ comprehensively restores the natural outflow pathways in mild-moderate glaucoma. Whereas other MIGS procedures treat only one aspect of aqueous outflow, ABiC™ comprehensively accesses, catheterizes, and viscodilates the trabecular meshwork, Schlemm’s canal, and importantly, the distal outflow system, beginning with the collector channels. A restorative procedure, ABiC™ preserves tissue and does not require permanent placement of an implant in the eye.
