Symmetrical Fit for your irregular cornea and keratoconus patients

Fitting patients with keratoconus and irregular corneas for contacts is now much easier for all practitioners and much more comfortable for the wearer. TruForm technology eliminates the guesswork for those with irregular corneas with the QuadraKone™ vision correction lens. “Quad-Technology” generates a precise fit for patients with asymmetric eyes by treating each of the eye’s four quadrants independently. That means the wearer receives a custom-made lens every time, specifically tailored to their unique eye shape. QuadraKone: the perfect fit for asymmetrical eyes.

The QuadraKone guarantee allows practitioners to successfully fit patients with very challenging keratoconus and irregular corneas.

QuadraKone uses new, technologically-superior lathes in conjunction with topography to cut the lens design with consistent, reproducible precision.

“Quad-Technology” features a controllable quad-aspheric periphery, which can increase or decrease the edgelift in four different quadrants of the eye. This produces an ideal fit for every contact wearer.

Around the clock advice from highly qualified and experienced fitting consultants is always available. Eye maps may be sent directly to a consultant’s email address.

TruForm products are backed by a 100% satisfaction guarantee.
