OPD-Station Comprehensive Visual Analysis SoftwareThe NIDEK OPD-Station software makes a variety of corneal, total eye and internal eye analysis possible using advanced,unique and intelligent functions including the Corneal Navigator and Holladay Summary.NAVWaveAn intelligent diagnostic technology to offer optimum refractive treatments with greater precision.Corneal NavigatorThe advanced & highly sophisticated CornealNavigator software is included in all NIDEKOPD-Station software packages. The technologicallyadvanced and unique software assists surgeons intheir patient diagnoses process. Utilizing variouscorneal parameters from topography, the CornealNavigator automatically determines corneal featuresand shows by percentage the possibility of having acondition of normal (NRM), astigmatic (AST),keratoconus suspects (KCS), keratoconus (KC), pellucidmarginal degeneration (PMD), myopic refractivesurgery (MRS), hyperopic refractive surgery (HRS), andpenetrating keratoplasty (PKP).*The Corneal Navigator is developed in collaborationwith Stephen D. Klyce, PhD & Michael K. Smolek, PhD.

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.
