Rose Kô Lens

Heralded as "a quantum leap forward in the evolution of lens design for the condition" of keratoconus the Rose Kô lens has become the world's most frequently prescribed rigid gas permeable contact lens for keratoconus.

Unlike traditional contact lenses, the complex geometry built into every Rose Kô contact lens closely mimics the cone like shape of the cornea, for every stage of the condition.

The result, a more comfortable fitting lens for patients and better sight (visual acuity).

The Rose Kô lenses complex geometry has only become possible since computer controlled contact lens lathes were developed to cut plastic to precisely the right shape.

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

  1. It's complex geometry can be customized to suit each eye and can correct all of the myopia and astigmatism associated with Keratoconus
  2. They are easy to insert, remove and clean
  3. They provide excellent health to the eye, because they allow the cornea to "breathe" oxygen directly through the lens
  4. Practitioners have the Rose Kô trial set fitting system which achieves a first fit success in over 80% of patients internationally.

Figure 1

Standard lens designs with fixed optical zones (OZ) do not ideally fit the cone shape of keratoconus patient's.  Figure 1 shows a standard lens that will yield unwanted pooling at the base of the cone and peripheral bearing that can seal off and cause corneal problems.

Figure 2

Figure 2 demonstrates the benefits of a smaller optical zone to fit the cone contour.  The design results in little tear pooling at the base of the cone and shows an even distribution of tears under the lens.

The Rose Kô system has set optical zones to maximize vision while maintaining good corneal health.
