Simulated ablation maps and resultant postoperative anterior corneal elevation maps. Preoperative Scheimpflug based anterior corneal elevation maps fitting by sphere and aconic surface (column A and column B, respectively), simulated ablation maps based on total corneal astigmatism correction and resultant postoperative anterior corneal elevation maps fitting by sphere (column C and column D, respectively), simulated ablation maps based on refractive astigmatism correction and resultant postoperative anterior corneal elevation maps fitting by sphere (column E and column F, respectively)
