Rose K2 Lenses – Hamilton & Burlington

The Rose K2 lens is a rigid and oxygen permeable contact lens designed for patients with keratoconus.

Keratoconus is a disorder of the anterior surface of the eye (the cornea). In simple terms, the cornea becomes thinner causing it to bulge from its normal round shape to a cone shape. This bulging can cause significant glare and halos, and can severely affect the way we see the world. Simple tasks like reading, watching TV or driving (especially at night) can become increasingly difficult. The visual distortion caused by keratoconus has been compared to viewing a street sign or light through  a rainy or wet windshield.

The progression of keratoconus is unpredictable, but in general the condition progresses slowly and can stop progressing at any stage. While keratoconus interferes with the clarity of a person’s sight it rarely causes blindness. In its early stages, keratoconus causes slight blurring and distortion of vision and increased sensitivity to glare and light. As the disorder progresses, the degree of vision obtained through glasses and soft  contact becomes less acceptable. At this stage, patients often seek out our custom or more specialized contact lenses for keratoconus, as well as other corneal disorders.

Unlike a scleral contact lens, the Rose K2 contact lens for keratoconus is smaller in size and rests on the cornea (clear front surface of the eye), as opposed to the sclera (the white of the eye). Since the cornea is much more sensitive than the sclera, it can take up to two weeks to fully adapt to the sensation of having this lens on your eye.

The Rose K2 lens has a number of features that make it ideal for keratoconus:

  • Its complex geometry can be customized to suit each eye and can correct all of the myopia and astigmatism associated with keratoconus.
  • They are easy to insert, remove and clean.
  • They provide excellent health to the eye, because they allow the cornea to “breathe” oxygen directly through the lens.
  • Practitioners have the ROSE K2 trial set fitting system which achieves a first fit success in over 80% of patients internationally.

Today’s contact lens options for keratoconus patients work very well to reduce glare, halos and distorted vision.  At Spectrum Family Eye Care our focus is fitting irregular corneas with specialized lenses that are both comfortable and healthy for your eye. Lenses like the Rose K2, as well as scleral lenses, have worked tremendously to help our patients see clearer and maintain a better quality of life.
