OPD-Station Comprehensive Visual Analysis SoftwareHolladay Summary*The NIDEK OPD-Station provides PSF, MTF and retinalimage simulations for total eye, cornea and internaleye.PSF SimulationCalculates the Point Spread Function (PSF) based onthe OPD-Scan measured data and corneal topographydata, and displays in simulation the distribution of thepoint spread.Retinal Image SimulationCalculates the distortion of incoming light based onthe results of PSF analysis, and displays the simulatedretinal image of the projected chart.* The Holladay Summary mapping is developed incooperation with Jack T. Holladay, MD.Contact Lens FittingThe contact lens fitting software “CL-Fit” isbundled with the NIDEK OPD-Station. Based on theOPD-Scan corneal topography data, the CL-Fitautomatically selects the most appropriate contactlens, achieving an optimal contact lens fitting for thepatient.
