The NIDEK OPD-Scan II provides information on corneal topography, wavefront, autorefraction, keratometry, and pupillometry in one unit, utilizing state-of-the-art imaging and analysis technology developed specifically to measure normal to highly aberrated eyes.
The system offers a variety of data maps to provide information on the total refractive error, wavefront, corneal shape, internal aberrations, and visual quality of the eye; allowing highly accurate and reliable information for optic diagnostics.

The OPD-Scan II utilizes the principle of skiascopic phase difference for refractive error map measurement. The retina is scanned with an infrared light slit beam, and the reflected light is captured by an array of rotating photo detectors over a 360º area.The corneal topography function utilizes Placido disc technology.

The system captures the image of reflected rings of light from the cornea and analyzes thousands of data points to plot the corneal contour, shape, and refractive power.The OPD-Scan II measures corneal refractive power by corneal topography, and total refractive error as the OPD map.

The Internal OPD Map plot is created by subtracting the corneal refractive power from the total OPD to display in diopters the distribution of refractive error contained in the internal eye.
