Lens Design & Materials
Rose K Lens
Heralded as “a quantum leap forward in the evolution of lens design for the condition” of keratoconus the Rose K lens has become the world’s most frequently prescribed gas permeable contact lens for keratoconus.
Unlike traditional contact lenses, the complex geometry built into every Rose K 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 K 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 K lens has a number of features that make it ideal for keratoconus:
- It’s 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 K trial set fitting system which achieves a first fit success in over 80% of patients internationally.
The Rose K lens design is manufactured using Boston® materials from Polymer Technology Corporation in the USA. Boston materials were chosen because of their excellent stability and surface characteristics achieved through the low silicon Aercor™ chemical architecture.
