3.5.5 Operation check
䕔
The corneal thickness test piece is for operation
checks. This test piece cannot measure or
calibrate the accuracy of the instrument.
The corneal thickness test piece allows you to check the operation of the
instrument.
1) Select “Auto” for the measurement mode.
2) Place the test piece in water and set the pachymetry probe
perpendicularly to start measurement.
3.5.6 Preparation for measurement
䕔
Cooperation by the patient is required to
perform measurement smoothly. Explain the
purpose of the examination and measurement
method to the patient before starting
measurement to help them relax.
1) Check the measurement condition settings and operation as
needed.
2) Apply topical anesthesia to the eye and have the patient sit down on
the chair or lie on their back so that they are in a comfortable
position while measurement is performed.
