Auto Refkerato ARKM-200


New Generation of Multi-Functional Instrument
A highly accurate machine which facilitates short examination times combined with ease of use making the ARKM-200 an essential for the professional. The advanced touch-screen display allows you to perform both Refraction and keratometry with one simple movement. Capture one eye on the display and the ARKM-200 will display both eyes automatically. The ARKM-200 allows efficient examination of patients with the new features.
  • Various settings like changing modes can be done on the touch panel display.
  • The wide viewed fixation target assures natural fixation to avoid accommodation of a patient's eye.
  • The quick thermal printer has shortened the total measurement time.


Automatic Measurement
  1. Use power assist joystick for rough alignment.
  2. Touch the centre of the pupil on the display with your fingertip and ARKM-200 will automatically align and begin measurements.
  3. Press the R/L Icon on the display and the instrumentwill automatically move to and measure the other eye.
  4. Printing is automatic.
Power Joystick
  • More the joystick ring up/down and the instrument head moves up/down quickly.
  • Move the joystick hand rest to the right/left or backward/forward and the instrument head moves to the right/left or backward/forward quickly.
  • Rotate the joystick ring and the instrument head moves up/down slowly.
  • Tilt the joystick and the instrument head moves in each direction slowly.
Power Chinrest
The chin rest can be moved by pushing the buttons on the front panel. No need to reach out to the chin rest for manual adjustment.
Refractometory
Normal Mode:
Fogging is applied automatically for each measurement for more accurate results.
Quick Mode:
Fogging is applied as needed for consecutive measurements.
IOL/CAT Mode:
The mode is used to measure cataract or pseudophakic eyes.
Keratometry
  • Short consecutive measurements and time provide reliable data.
  • Measurements at O6.0mm (R=8.0mm) as well as at O3.0mm give you enough information for contact lens fitting.
  • Base curves of contact lenses are stored, categorized and suggested manufactures are automatically printed.
Diameter Measurement of Cornea and Pupil
Measurement can be done easily by moving the two cursors on the display to the boundary of Cornea or Pupil.This is useful for deciding the diameter of a contact lens and for other contact lens fitting practices.
