These formulae are for use in patients who have had prior refractive surgery. Each such patient is unique
and results may vary widely. You should interpret all IOL power recommendations with caution.

13.2 Checking the calibration
The calibration must be checked when the device has been transported from one place to another
and when it has suffered an impact or thermal shocks.
Check the calibration of the device every day before starting patient examinations.
Set the calibration tool supplied with the device (Figure 14) in the special holes in the chin rest and press until
the tool is blocked on the device. Check that the calibration tool is perfectly aligned with the device. If the
calibration tool is positioned correctly, all the rings of the Placido disk should be seen reflected in the center
on the surface of the hemisphere (Figure 15).
