Topo guided removal of epithelium in keratoconus (TREK) regularizes thin corneas, advanced keratoconus & decentered cones. Ablation depth of 25μ beyond thinnest epithelial thickness is applied over the highest steepening using PTK-CAM module of Schwind Amaris with manual removal of surrounding epithelium over 7 mm area & accelerated CXL. TREK is safe, effective & novel tissue sparing treatment in KC.
