- A hyphen (-) is shown in CCT and CCT (US) when CCT cannot be
measured.
- It can be set on the System Setup screen whether to show “CCT (US)” or not.
Refer to “3.7.3 Application" for setting method. The initial setting is OFF.
- CCT (US) is calculated by adding a specific thickness (offset value) to
CCT. The offset value can be changed on the System Setup screen.
Refer to “3.7.3 Application" for setting method. The initial setting is
“13ȝm.”
Ɣ Checking distribution according to sizes/shapes
Distribution according to cell sizes and shapes obtained by automatically
analyzing the displayed image of endothelium tissues is displayed using a
histogram on the single eye analysis screen.
- The class width of distribution according to cell sizes can be set on the
System Setup screen. Refer to “3.7.3 Application" for setting method. The
initial setting is “100 ȝm

.”
- If the cell trace line cannot be extracted correctly by automatic analysis,
neither a bar nor a number is displayed on the histogram.
Ɣ Changing displayed image
