Huvitz HRK-8100A Auto Ref-Keratometer

The Huvitz HRK-8100A is a premium wavefront-based auto ref-keratometer built around a proprietary micro lens array that delivers significantly richer refractive data than conventional autorefractors. In addition to standard sphere, cylinder, and axis measurements, it provides comprehensive higher-order aberration analysis through a graphical Zernike map — data previously available only from dedicated wavefront aberrometers. Retro-illumination and color view modes add anterior segment visualization for contact lens fitting assessment and lenticular opacity screening. For practices that want higher confidence in their pretest refractive data and more complete aberration information without stepping up to the full feature set of the HRK-9000A.

Where The HRK-8100A Wins

If your pretest lane needs wavefront-quality refractive data and higher-order aberration analysis without the full MGD and VA feature set of the HRK-9000A — the HRK-8100A delivers premium refraction confidence from a single compact instrument.

Best Fit

Comprehensive optometry and ophthalmology practices modernizing their pretest lane with premium wavefront-quality refractive data — stronger data confidence than commodity autorefractors, without the additional MGD and VA features of the HRK-9000A.

Why This

Standard autorefractors give you sphere, cylinder, and axis. The HRK-8100A adds higher-order aberration data graphically displayed in a Zernike map, contact lens base curve measurement, and anterior segment visualization.

Practice Impact

Better pretest data means fewer chair-time refinements during subjective refraction, more confident customized lens prescriptions, and useful pre/post-refractive surgery evaluation from a single compact instrument.

Platform Strengths

Why Practices Choose HRK-8100A

Wavefront-Quality Refractive Data

The micro lens array captures hundreds of data points for higher-order aberration analysis, delivering refraction data with depth that standard autorefractors cannot match.

Zernike Aberration Mapping

Graphical display of coma, trefoil, spherical aberration, and secondary astigmatism — data previously available only from dedicated wavefront aberrometers, now accessible during routine pretest.

Anterior Segment Visualization

Retro-illumination mode (2.5x brighter than previous generation) reveals lenticular opacity, while the full-color CCD camera and white LED enable contact lens fitting assessment directly from the autorefractor.
