13 Test measurement with the Pentacam® AXL
In addition to the manually performed backup, it is also possible to
automatically run a backup when exiting the Patient Data Management
system. The settings required for this can be made in the "Settings" area,
see User Guide.
The Pentacam® AXL is tested and calibrated at OCULUS.
OCULUS Optikgeräte GmbH recommends to carry out additional regular
test measurements with the Pentacam® AXL.
Start the test with a measurement of a human eye.
Carry out at least five successive measurements on each eye. Calculate
the arithmetic mean and log the results.
Once a month, this measurement sequence should be carried out on the
same eye as described above.
Compare the arithmetic mean from the initial measurement with the cur-
rent measurement.
The following table depicts the tolerance range between the result of the
initial measurement and the result of the current measurement:
Curvature
Pachymetry
If the difference between the initial value and the current value lies out-
side the tolerance range, please contact our service or your marketing
authorisation holder. The values are shown in the overview display, for
example; please refer to the
