OPERATING PROCEDURE: AR (refractive error) and KM (corneal curvature radius) Measurements
3.3.2 Cataract measurement mode
When measurement is not possible due to cataract or abnormal eyes during AR (refractive error)
measurement, the device enters cataract measurement mode automatically.
In cataract measurement mode, measurement conditions are changed so that measurement results
can be easily obtained.
When the device is placed in cataract measurement mode,
“
” is displayed on the screen and then measurement
starts.
The auto tracking and auto shot functions work in the
same manner as in normal measurement mode.
Any of the following operations cancels cataract measurement mode:
•
Switching the eye to be measured between the right eye and left eye.
•
Pressing the clear button.
•
Pressing the print button.
O
Printout sample in cataract measurement mode
According to the “45. CAT MARK” parameter setting, “*” indi-
cating that measurement has been taken in cataract mea-
surement mode is printed as shown on the right.
The factory setting is “NO”.
-OVR
(Outside corneal curvature radius negative
range error)
The corneal curvature radius is too small and not within the mea-
surable limit.
COVR
(Outside CYL range error)
The cylinder value is over the measurable limit.

in comparison with normal measurement mode.
