e) Scale of pachymetry map
Corneal thickness is shown in colors ranging from
blue (thick section) to red (thin section). Absolute scale
or convention scale can be selected, and each scale
visually shows the distribution of the corneal thickness
on the color map.
● Absolute: Absolute scale
The absolute scale uses the same color coding as the
curvature map. The corneal thickness is divided into 26
ranges and each thickness range is uniquely shown in
corresponding colors, so the absolute scale allows you
to easily compare the data with other measurement
results.
The range of the absolute scale is 260 – 760 μm.
The center of the scale is displayed in 20 μm increments
regarding 580 μm to be the center value, which is
displayed in bright green.
