Rose K ®

Rose K® is the single most frequently prescribed lens design for the correction of keratoconus and irregular cornea conditions in the world. All ROSE K® designs feature a simple, systematic fitting approach, a flexible edge lift system and aberration control aspheric optics that provide outstanding acuity, reduced flare and glare and minimum lens mass.

Menicon currently manufactures, distributes or licenses ROSE K® lenses in 90 countries worldwide.




The ROSE K2 keratoconus lens design is the most widely prescribed RGP keratoconus lens in the world. It is a multi-spherical posterior design with aberration control aspheric optics across the back and front optic zone diameters and is available in any toric lens design.




This lens design can be used for the irregular cornea where other designs have failed. It has a larger overall diameter and utilizes the same systematic fitting approach of the ROSE K2 design and has secondary applications for nipple and oval cones.


ROSE K2 Post Graft


This lens is designed for postoperative recovery and improvement in vision. It is a multi-spherical posterior design with some reverse curve geometry and aberration control aspheric optics across the back and front optic zone diameters.


ROSE K2 NC Nipple Cone


The ROSE K2 NC primary indication is for advanced and moderate nipple cones and secondary application for any defined nipple cone. The design characteristics are a very small aspheric back optic zone diameter which decreases as the base curve steepens and a very rapid peripheral flattening from the back optic zone.




The eagerly awaited addition to the ROSE K2® family. This semi scleral lens is used for Keratoconus, PMD, Post-Surgical and any irregular corneal condition that cannot be successfully fitted within the limbus. The ROSE K2 XL follows the same systematic fitting system that is advocated for the four other ROSE K2® designs, and is extremely east to fit even for fitters who have not fitted a semi scleral design before.

ROSE K2 Soft


The new ROSE K2 Soft design is a daily wear soft lens for irregular corneas, available as a 3 month replacement lens manufactured from silicone hydrogel materials. The primary indications are intolerance to GP lenses, new contact lens wearers with irregular corneas, early to moderate irregular corneas, or conditions where the environment may be unsuitable for GP wear or where a GP lens may be unstable, such as sport.

ROSE K2 Soft uses the same simple, proven 5-step fitting method common to all ROSE K® designs. The design features an aspheric back optic zone, front surface toricity and front surface aberration control for optimal visual acuity. Additionally, ROSE K2 Soft offers precise edge lift control, prism ballast stabilization and reverse geometry for a trouble-free fit.




The ROSE K ACT is the latest design enhancement that can be applied to any of the ROSE K® designs. ACT (asymmetric corneal technology) enables the practitioner to specify a different posterior edge lift in a specific quadrant of the contact lens (normally inferior) to that on the rest of the posterior surface.
