Easy-to-Use Color Touchscreen Control PanelAll operating procedures can be performed with the touchscreen control panel. The optimized user interface
provides an intuitive operator experience. The KR-1 rapidly captures data from the right eye before
moving automatically to capture the left eye. An easy-to-use manual capture option is also available,featuring manual focus coupled with auto-alignment.

Auto/ Manual* Pressing the ‘Start’ button results in immediate data capture, which may be necessary for less cooperative patients, or patients with signifi cant corneal
disease, that can make auto-alignment and focusing diffi cult.

5Flexibleand Space
Saving Layout
The control panel can be rotated in anydirection. The compact device enables theoperator to support the patient easily during
measurement, even if the patient’s eyelid
needs to be lifted. These unique aspects
will contribute to space saving
and flexible layout in your eye
examination room.

Compact Ergonomic Design
The KR-1’s ergonomic design provides a more
comfortable position for the patient with an inclined
optical head (5°). The compact instrument enables
easier access for patients.
