Wavefront-Versus Topography-guided Customized Ablations With the NIDEK EC-5000 CX II in Surface Ablation Treatment: Refractive and Aberrometric Outcomes

To compare the long-term refractive outcomes and changes in higher order wavefront aberrations in patients undergoing photorefractive keratectomy (PRK) with topography-guided (CATz) or wavefront-guided (OPDCAT) ablation algorithm using the NIDEK Advanced Vision Excimer Laser System (NAVEX).A retrospective 12-month follow-up study was conducted of 226 eyes undergoing PRK. The NIDEK EC-5000 CX II excimer laser and Final Fit 1.11 treatment planning...
