(3) Measure the corneal periphery.
Have the examinee look at the fixation target that is
illuminating. A measurement position in the guiding
mark is indicated in blue. Carry out alignment and
press the measurement switch.
When the measurement is completed, the guiding mark
changes blue to light blue and the next measurement
position becomes blue.
(4) Complete the peripheral measurement for all four positions. When it is completed, all positions of the
measurement guiding mark will turn to light blue.
Proceed to measure the other eye according to the procedure above.

For peripheral measurement, align the
alignment mark to the center of the reticle
mark, not to the center of pupil.
NOTE
When you wish to measure some position again, use P.K. target selection switch to
move the cursor to the position you wish to measure.
When you can not take any data, or you do not need all data of the peripheral
measurement, you can skip some position using P.K. target selection switch.
In such a case, the result of the position measured only is displayed. The center,
however, must be measured all the time.
NOTE
