● In contact lens mode (Fig. 3)
The distance between the start line of the waveform (0 mm point) (10) and the
retina caliper line (13) is shown in the axial length field, that between the start
line of the waveform (10) and the caliper line for the front of the crystal lens (11)
is shown in the ACD (anterior chamber depth) field, and that between the
caliper lines for the front of the crystal lens (11) and for the back of the crystal
lens (12) is shown in the Lens field.
(Fig. 3)
● In immersion mode (Fig. 4)
The distance between the cornea caliper line (14) and the retina caliper line (17)
is displayed in Axial length, the distance between the cornea caliper line (14)
and the caliper line for the front of the crystal lens (15) is displayed in ACD, and
the distance between the caliper line for the front of the crystal lens (15) and the
caliper line for the back of the crystal lens (16) is displayed in Lens.

e) Selecting specific measurement data to be used for calculating IOL power
The average value is normally adopted for the measurement data to be used in
calculating the IOL power, but specific data can also be selected.
(Fig. 1)
1) Use the selection cursor movement buttons (1) to move the selection cursor
(2) to the data which is to be used in calculating the IOL power. To use the
average value in IOL power calculation, move the selection cursor (2) to the
average data at the bottom.
