Semi-Scleral Design for Irregular Corneas
As reported in the March Product Spectrum, Menicon recently launched the Rose K2 XL semi-scleral lens. The company says that the primary indications for this lens are keratoconus, pellucid marginal degeneration, post-graft, corneal rings, post-LASIK ectasia, advanced dry eye, and any irregular corneal condition that cannot be successfully fitted within the limbus. Menicon also states that the lens is suitable for wear in polluted work conditions, stability for sport or working environments, for corneal GP intolerance, and for piggyback systems.
The Rose K2 XL design features an aspheric back optic zone that decreases as base curve steepens. According to Menicon it also features front-surface aberration control and precise edge lift control. Rose K2 XL is manufactured in Menicon Z, Lagado Tyro 97, and Boston XO (Bausch + Lomb). Parameters include base curves of 5.80mm to 8.40mm, diameters of 13.6mm to 15.6mm (standard diameter of 14.60mm), powers of +30.00D to −30.00D, and edge lifts in nine options: five standard lifts ranging from Double Flat to Double Steep, which the company contends will optimally fit 90 percent of cases, with other options available on request.
The Rose K2 XL fitting set features 16 lenses manufactured in Menicon Z or Lagado Onsi 56 material. The fitting set base curves range from 6.00mm to 8.00mm in the standard diameter of 14.60mm and the standard edge lift (0). Rose K lenses are available in the United States through Blanchard Contact Lens, Art Optical, or your local Rose K distributor.
