Shear Power. Pure Canaloplasty.

Shear Clear™ Technology is iTrack™ Advance's approach to viscoelastic delivery.

Ever wonder what would happen if viscoelastic during canaloplasty wasn’t so… viscous?

Shear Clear™ Technology transforms cohesive viscoelastic into a low-viscosity fluid during canaloplasty, enabling it to circulate more freely and penetrate deeper into the trabecular outflow pathway.

The Science Behind the Power

What is Shear Thinning?

Viscoelastic shearing — or shear thinning — is how viscoelastic temporarily changes viscosity under the high shear stresses generated by Shear Clear™ Technology.

At rest, cohesive viscoelastic behaves like a high-viscosity gel.

Shear forces in iTrack™ Advance temporarily transform the viscoelastic into a fluid-like state.

Shear forces are released, returning the viscoelastic to its original gel-like state.

What is Shear Clear™ Technology?

Viscoelastic shearing — or shear thinning — is how viscoelastic temporarily changes viscosity under the high shear stresses generated by Shear Clear™ Technology.

The patented internal micro-architecture of the microcatheter — including a woven nitinol guidewire — generates controlled turbulence that maximises shear stress.

The ViscoInjector™ connects via a 24-inch infusion line, through which viscoelastic is pushed under high pressure to maximise shear stress.

How Shear Clear™ Works

Optical rheology testing has shown iTrack™ Advance can generate a high shear rate, achieving a 190-fold reduction in viscosity.*

Change in Viscosity of Healon Pro Over Time During Priming, Delivery and Post-Delivery with the iTrack™ Advance*

*In-house bench testing data using a proprietary optical rheology test apparatus to assess the change in viscosity over time during viscoelastic delivery with the iTrack™ Advance. Bench testing data may not be indicative of clinical outcomes. Data available on reasonable request.

Shear Clear™ Technology at a Glance

Once thinned with shear force, viscoelastic can circulate more freely within Schlemm's canal.*

Visible intraoperative blanching of the limbus vessels and episcleral venous system may illustrate this effect.*

The thinned viscoelastic may penetrate deeper into the trabecular outflow pathway, including collector channels.*

As post-delivery shear forces dissipate, the viscoelastic regains viscosity.

*Clinical effects depend on anatomy and surgical technique. Results may vary.
