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.
