A family of solutions for a universe of irregular corneas.

ROSE K logo

ROSE K is one of the most frequently prescribed lens designs 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 89 countries worldwide (as of May 2025).

Simple & Easy

Complete family

The ROSE K2 family of designs is a comprehensive offering that includes both RGP and soft lenses for irregular corneas

Simple to fit

All ROSE K2 designs follow the same simple, systematic five step fitting process

Unique Design

This design automatically adjusts as the base curve changes, ensuring optimal fit, comfort, and performance across all corneal shapes and sizes

Advanced Fitting Options

Advanced fitting options are available including Toric Periphery (TP), Asymmetric Corneal Technology (ACT), front, back and bi-toric designs, and Quadrant Specific Edge Lifts (QSEL)
