Visual Recovery: Rose K2™ Post-Graft / IC for Complex Corneal Profiles

Product Introduction The Rose K2™ Post-Graft / IC is a highly specialized Rigid Gas Permeable (RGP) lens designed for patients who have undergone corneal transplantation (Post-Graft) or exhibit extreme corneal irregularity due to surgery, trauma, or medical conditions (IC - Irregular Cornea). Post-surgical corneas often feature significant steps, elevation changes, or high astigmatism at the graft-host junction. This lens utilizes a unique geometry to vault over these irregularities and re-establish a perfect spherical optical interface.

Core Technology & Benefits

• Multi-Curve Posterior Geometry: Post-graft corneas are unpredictable—they can be prolate (steep) or oblate (flat). The Post-Graft design allows for independent curvature adjustments in the central and peripheral zones, enabling the lens to "bridge" over suture lines without putting mechanical pressure on the delicate graft tissue.

• Aberration Control Optics: Surgical corneas are frequently plagued by severe glare and higher-order aberrations. The optical zone of this lens is precision-calculated to filter scattered light, significantly improving visual contrast and clarity in complex lighting environments.

• Adjustable Edge Lift: To accommodate peripheral edema or sudden contour changes common after surgery, practitioners can precisely adjust the edge lift. This ensures healthy tear exchange and minimizes mechanical irritation to sensitive surgical sites.

• Advanced Gas Permeable Materials: Because grafted corneas may have compromised endothelial function, these lenses are made from high-Dk materials. This ensures maximum oxygen delivery, which is vital for maintaining graft clarity and preventing graft rejection.
