Optimised toric lens geometry™

Patients with astigmatism need contact lenses with different optical powers in different meridians. To correct their vision, those meridians must be oriented in just the right way and remain stable. While lens movement on the cornea is important for healthy contact lens wear, too much movement with toric lenses can diminish the quality of vision for your astigmatic patients.

Thanks to our Optimised Toric Lens Geometry™, CooperVision’s toric lenses provide your astigmatic patients with the visual acuity and stability they need.

How it works

Optimised Toric Lens Geometry™ produces a multifaceted toric lens that’s designed to provide predictable, consistent visual acuity, lens stability, fit and comfort in standard or extended range prescriptions.

  1. Uniform horizontal ISO thickness

Improves lens stability and reduces rotation for better visual acuity*

  1. Smooth, continuous ballast

Maximises comfort* during eyelid interaction

  1. Larger toric optic zone

Provides clear visual acuity*

  1. Optimised ballast toric design

Provides a stable, comfortable fit*

In addition, a unique back surface curvature reduces on-eye movement to support stable lens positioning and dependable fit.
