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.
