Corneal Wavefront-Guided (CWG) laser ablation is a form of Topography-guided procedure that translates Topography to Wavefront aberrations. Treating the latter in a selective fashion offers the possibility of consuming less stromal tissue, hence minimizing postoperative refractive surprises, leaving more room for a more precise enhancement, reducing both the corneal biomechanical impact and response. This chapter explains the theoretical and clinical concepts behind corneal Wavefront-guided ablation vis-a-vis Topography-guided and ocular Wavefront-guided treatments, and offers step-by-step, concrete guidelines to implement it in daily practice.
