NOTE
• The instrument can memorize up to 10 measurements each for right and left eyes.
If the measurements exceed 10, older data will be cleared in turn.
• If the AI Mode parameter is set to “NO”, take about three shots for AR measurement.
If the measurement result is not stable, take some additional shots.
• If you want to repeat measurement several times without printing, set the Print parameter
to “Manu.”. By pressing the start button, “< FINISH >” sign disappears and serial
measurement starts again.
2. Measure the other eye in the same manner.
NOTE
• When error or error data

appears, the cause may be one of those mentioned below. If
those signs appear again after repeating measurement, check the following.
a. Patient blinked during measurement.
b. The eyelid or eyelash is on the Min. pupil mark.
c. The patient’s pupil is smaller than the Min. pupil mark. (Let the patient sit in a
dark room for a while and wait until the pupil diameter becomes large enough for
measurement.)
d. Retinal reflection is extremely low due to an optical disease such as a cataract.
e. There is some unusual reflection on the cornea during measurement. (In this case,
measurement may not be performed unless IOL mode is on.)
f. There is an extreme distortion on the cornea.
*3 < Error data >
Data that the confidence index of AR measurement is “E”. (See “6.1 System Setups”.)
