NIDEK Advanced Vision Excimer Laser System

Final Fit^TM Custom Ablation Software

The NIDEK FinalFit^TM software receives the measured data from the OPD-Scan II, and performs a simulation of postoperative corneal shape, and generates excimer laser shot data using the data imported from the OPD-Scan and target correction data that are entered.


Component maps illustrate the stereoscopic or contour ablation amounts which were put through a simulation.

NAVWave An intelligent diagnostic technology to offer optimum refractive treatments with greater precision.

• Shot Data Generation
  The Final Fit^TM software evaluates and converts the OPD-Scan II's refractive and topographic data to produce the precise customized ablation parameters for the EC-5000CX/CXII/CXIII excimer laser systems.These unique algorithms control the EC-5000's MultiPoint^TM Ablation Module to enable multiple, simultaneous localized ablations to correct higher order optical aberrations, corneal irregularities and decentered ablations.
  
  
• Comparison of Postoperative and Preoperative Data
  
  
• Nomogram Functions
  The Final Fit^TM software offers NIDEK's standard nomograms, which are tables for correcting theoretical amounts of correction in diopters based on clinical results and using various environmental factors like temperature and humidity.
  
  
• New Innovative Ablation Algorithms
  New innovative ablation algorithms (CATz, OATz, OPDCAT) provide exceptional treatment accuracy and visual outcomes.
  

  OATz	-Optimized Aspheric Treatment Zone- Ablations with Transition Zone (TZ) optimized to prevent Longitudinal Spherical Aberration (Red Ring), which can cause the loss of night vision, halos, glares and star bursts.
  CATz	-Customized Aspheric Treatment Zone- OATz with topography-guided multipoint ablation to reduce corneal irregularities, such as irregular astigmatism, de-center, central island, etc.
  OPDCAT	-OPD-Guided Customized Aspheric Treatment- Maintains corneal asphericity with aspherical ablation, and applies OPD-Guided (Wavefront Guided) multipoint ablation to reduce aberrations for the total eye.
