Tomey OA-2000 - Verification When Measuring Anterior Chamber Depth and Crystal Lens Thickness

4.4 Verification when measuring anterior chamber depth and crystal lens thickness
Since there are many waveforms of the cortex etc. of the crystal lens when
measuring an eye with cataracts, the front and rear of the crystal lens may not be
captured.
In this case, adjust the waveform display line on the scanned image up and down,
find and display the position where the largest waveforms are shown, and move
the caliper line to the point of the front of the crystal lens.

Waveform of the rear side of
the crystal lens is small.
