Final Fit TM Custom Ablation SoftwareThe NIDEK Final Fit TM software receives the measured data from the OPD-Scan, and performs a simulation of postoperativecorneal shape, and generates excimer laser shot data using the data imported from the OPD-Scan and target correction datathat are entered.NAVWaveAn intelligent diagnostic technology to offer optimum refractive treatments with greater precision.Shot Data GenerationThe Final Fit TM software evaluates and converts theOPD-Scan's refractive and topographic data toproduce the precise customized ablation parametersfor the EC-5000CXIII excimer laser system. Theseunique algorithms control the EC-5000's MultiPoint TMAblation Module to enable multiple, simultaneouslocalized ablations to correct higher order opticalaberrations, corneal irregularities and decenteredablations.Comparison of Postoperative andPreoperative DataThe Final Fit TM software compares post-operative datameasured by the OPD-Scan with the pre-operative ortarget data.Nomogram FunctionsThe Final Fit TM software offers NIDEK’s standardnomograms, which are tables for correctingtheoretical amounts of correction in diopters based onclinical results and using various environmental factorslike temperature and humidity.Component Maps: Illustrates the stereoscopic orcontour ablation amounts which were put through asimulation.Total Ablation - illustrates the simulated ablationamount.“Sphere” Ablation - illustrates only symmetriccomponents with respect to rotation axis such asspherical/aspherical components.“Cylinder” Ablation - illustrates only axisymmetriccomponents such as cylindrical components.“Irregular” Ablation - illustrates only irregular(astigmatic) components that have been extracted.("CATz" or "OPDCAT" ablation mode only)
