Beyond the Horizon: Rose K2™ XL Semi-Scleral Lens for Complex Ocular Surfaces

The Rose K2™ XL is a semi-scleral Rigid Gas Permeable (RGP) lens. With a significantly larger diameter than standard RGPs (typically 13.5mm to 16.0mm), the XL is designed to vault entirely over the cornea and rest on the relatively insensitive sclera (the white of the eye). Combining the crisp optics of a rigid lens with the stability of a soft lens, the Rose K2™ XL is the definitive visual solution for severe keratoconus, post-graft cases, and severe dry eye.

Core Technology & Benefits

• Vaulting Geometry: The core principle of the XL is "to vault." It creates a space filled with saline over the cornea, avoiding any physical contact with the corneal surface. This eliminates mechanical friction on sensitive cones and provides a continuous "fluid reservoir" for the eye.

• Scleral Landing System: The majority of the lens weight is distributed onto the sclera. Because the sclera has far fewer sensory nerve endings than the cornea, the XL offers a level of comfort that far exceeds that of traditional rigid lenses.

• Superior Stability and Centration: Due to its large diameter, the lens is highly resistant to decentration or dislodgement. It maintains a stable optical center even during heavy blinking or rapid eye movements, solving the "foreign body sensation" and "wobbling" issues common with smaller RGPs.

• Aberration and Visual Optimization: By utilizing the fluid reservoir under the lens, it perfectly offsets astigmatism and aberrations caused by extreme corneal irregularities. For patients who cannot tolerate standard RGPs but require high-definition vision, the XL provides exceptional clarity.
