(6) Setting focus and location of the model eye
①With watching monitor, control the lever to move and set the aiming point around the inside collimating mark.
②Move and set the aiming point on the middle of the inside collimating mark.
③Control the lever back and forward and make the mire ring to be seen clearly.
(7) Measurement
• Manual Measurement
(a) Focus a point and location of the model eye in accordance with (6) above.
(b) Press the measurement button. Then if an error massage occur on the monitor, do (a) again and
press the button again.
(c) Check and compare the measurement result with the value of diopter written on lower part of the model eye.
Unless it is satisfied, measure and check gain as a same way.
• Auto Measurement
Operate the auto measurement continuously.
(a) Press AUTO button on the operating board
(b) Focus a point and location of the model eye in accordance with (6) above.
(c) Measurement would start automatically when the Bright Dot occur in the inside collimating mark.
(d) Do the process (c) of Manual Measurement part.

5-1 Continuous Refraction/Cornea Measurement (R / K Mode)
In R / K Mode, you would do Cornea measurement first and Refraction measurement.
(1) Converting to R / K Mode
Press MODE button until 'R/K' icon displayed on the top left of the monitor.
< Measurement Scene>
(2) Setting up the height of eye
Make a patient to sit on the chair and put his chin and forehead on the chin rest and forehead rest.
To set up the height of the eye, turn and control the chin rest control lever.
(3) Setting focus and measurement location.
(a) Control the lever and set the patient’s right eye to be seen on the monitor.
(b) Make him to see the fixed target on the middle of inside .
(c) With watching monitor, control the lever to make the ‘mire ring’to be seen clearly.

(d) If you are not satisfied with controlling lever, you push the stage for all directions to focus.
• When pupil and center of collimating mark do not fit, request to the object man to see the red roof of the
center of the picture.
(4) Measurement
(a) Press Measurement Button.
(b) After measuring, the result would be displayed on the monitor.
(d) When you measure continuously, the last result would be displayed.
(e) You can select an expression of Vertex Distance, the value of CYL and KER in USER's SET.
(Refer to USER's SET)
NOTES:
①If the pupil is out of the outside collimating mark, an error could happen.
②An error could happen by the modification of cornea after surgery or the lens pollution.
③During IOL switch is on, the trust-ability of measurement can be low.
④IOL button is only operated on 'R/K Mode' and 'REF Mode'.
⑤You can convert to IOL or normal with pressing IOL button.
(5) Continuous Measurement; You can measure continuously if it ' s necessary.
(a) Whenever you measure, the last result would be displayed .
(b) Last 10 Measurement results but except 'error' can be remembered.
(c) Those results would be seen on the monitor in DISPLAY MODE.
(6) Measuring the eye other side.
(a) You measure a left eye to push the stage to right with the control lever.
(b) After the binocular measurement, the PD (pupil distance) would be displayed on the monitor.
• If you push the stage to right eye without pressing the PRINT button, then the last measurement result of
right eye would be displayed on the monitor. Then you press the button, the new measurement result would
be added.
