iTrack™ Microcatheter

Featuring a proprietary, patented design, iTrack™ is the only illuminated, micron-scale microcatheter, designed to viscodilate Schlemm’s canal during 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.

Minimally Invasive. Maximally Effective.

Less invasive than traditional glaucoma surgeries, clinical studies have shown that Canaloplasty can significantly and durably reduce IOP without the risks and discomfort associated with trabeculectomy. It can therefore be offered earlier in the disease process. Unlike conventional glaucoma surgery, Canaloplasty does not produce a filtering bleb and can therefore be performed on patients who wear contact lenses. Patients who have undergone canaloplasty can continue normal day-to-day activities directly following treatment and require minimal post-operative follow-up.
