In the early stages of keratoconus, eyeglasses or soft contact lenses may be able to provide the patient with clear and comfortable vision. For highly irregular corneas, however, eyeglasses or soft lenses do not provide a good outcome for visual correction. As keratoconus becomes more advanced, rigid gas permeable contact lenses become the first choice to correct vision. Since its approval from the FDA in 1995, the Rose K lens has become available to eye care specialists in over 50 countries. This lens has several characteristics that make it an ideal treatment for keratoconus:
- Designed using complex computers and special digital lathes.
- Their complex geometry account for the irregular shape of the cornea in all stages of the condition (from mild to advanced)
- They can be custom designed for any eye and can correct the refractive error (myopia or hyperopia) and astigmatism associated with the keratoconus.
- Made from highly “breathable” material, these lenses allow oxygen to penetrate directly through the lenses, promoting health to the eye while allowing the patient to comfortably wear the lens for hours on end.
The result is a lens that fits very well over an irregular eye, leading to great comfort and clear vision. Because keratoconus is a progressive disease by nature, the Rose K lens must be fitted with extraordinary care and reevaluated at least every year by the contact lens specialist.
