Simple Fitting. Expert Results.

Our complex data, your streamlined fitting.

Designed with new and seasoned fitters in mind, the Europa Tangent simplifies the fitting process by using a three-zone fitting system, so you can focus on the changes you want and not the ones you don’t. Customized fitting does not need to be complex.

The Streamlined Tangent provides:

  • Contour adjusting technology; limbal and landing curve enhancements are derived from profilometry data.
  • Parameter independence; focus on the changes you want, not the ones you don’t.
  • Step-system fitting; streamlines, easy-to-understand three-zone fitting system delivers fitting success.

Troubleshoot with Tangent

My patient has significant blanching and/or impingement 360 around the scleral zone.
OR
There is too much compression on lens removal.

Your patient can be transitioned into the Europa Tangent design at any point in the warranty. Our Consultation team is there to assist you with changing to the Tangent design for no additional cost.

We offer a 12-lens Tangent Fitting Set that is available to scleral lens fitters of all experience levels and is an ideal option for fitters wanting independent parameter adjustments & step system fitting.

Scleral Lens Case Reports

Coming in for a (Tangential Scleral) landing, Visionary Optics is featured in the recent Contact Lens Spectrum.

Customized, Not Complex.

Streamline your scleral fitting.

Independent adjustments that will not affect the other lens fitting characteristics: When using the new step system on the Europa Tangent lens, changes can be made to the central clearance or scleral zone of the Europa Tangent design without affecting other lens parameters (up to + 300μ). Each step is done in 50μ increments.

How is the Tangent Design Different Than the Europa Design You Know and Love?

The Europa Tangent design incorporates a single-curve scleral landing zone that is tangential to the average scleral curvature. With this design, the five curvatures that are present in the Europa Standard design are compounded into three parameters in the Europa Tangent design.

DIAMETER

CENTRAL ZONE
(Base Curve / Optical Zone)

The Europa Standard base curve controls how much the lens vaults over the cornea and plays a primary role in the overall sag of the lens.

The Europa Tangent base curve & optical zone is identical to the Europa Standard Design.

LIMBAL ZONE

Mid-Peripheral Zone
The Europa Standard PC1 reverse curve controls clearance over the mid-periphery of the cornea and the limbus

Transition Zone
The Europa Tangent PC1 curve is identical to the Standard design, however, it is slightly wider to allow for adequate limbal clearance with the flatter periphery.

SCLERAL ZONE

The Europa Standard periphery consists of three different curves that control how the lens rests on the conjunctiva/sclera.

The Europa Tangent consists of a single-curve landing zone patterned after our freeform lens designs.
