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.
