Huvitz HRK8000A

 

The HRK-8000A Wavefront auto refractor/Keratometer is the newest generation instrument from Huvitz. This model combines the features of an auto refractor, auto keratometer and an aberrometer into one convenient-to-use instrument. The HRK-8000A is based on the Hartmann-Shack principle and focuses on measuring second-order aberrations, which result in myopia or hyperopia and regular astigmatism. Because correcting second-order aberrations has the highest impact on acuity, which is the eye’s ability to distinguish object details and shape. Wavefront Maps - The HRK-8000A leads better understanding for patients’ eye conditions since it graphically shows the second-order aberrations including myopia, hyperopia and astigmatism. In addition the wavefront maps can be printed out. 

RMS (root mean squared) – The HRK-8000A provides RMS to quantify the amount of aberration and describe the magnitude of an eye’s second order aberration for 3.0 mm pupil size.

 

 Residual Astigmatism - The HRK-8000A measures the refractive error of the total eye, corneal astigmatism and calculates Residual astigmatism. This valuable information provides more information in regards to the eye as an entire system. In addition the residual astigmatism values can be printed out.

 

Peripheral Keratometry - The HRK-8000A is capable of providing five directional keratometry readings, one central and four peripheral readings. This additional information offers enhanced data for better contact lens fitting.

 

Continuous Measurement Mode - While pressing and holding down the joystick button, continuously measurement can be completed without a delay to fog the patients vision. This provides quick and rapid measurements.
