Automatic keratometry is a snap with the KM-500 Hand-held Keratometer. The KM-500's unique viewing and alignment window lets you observe the targeted eye from any distance. There is no need to dance "cheek to cheek" with your patient.
Measurement is simple. View the eye through the window and move the KM-500 towards the eye. When the mire ring appears on the cornea, slowly move the unit closer. The KM-500 will fire automatically when properly focused. Readings appear instantly on the LCD display. Both left and right readings display simultaneously.
