This biometry test piece cannot measure or
calibrate the accuracy of the instrument.
1) The biometry test piece provided with the instrument allows you to
check the operation of the instrument.
2) Select “Aphakic eye” for the eye type to be measured.
3) Wet the surface of the test piece and set the biometry probe
perpendicular to the surface to start measurement.
3.3.5 Preparation for measurement
䕔
Cooperation by the patient is required to
perform measurement smoothly. Explain the
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 for the eye and, in chin-rest measurement
mode, adjust the height of the chair, optical table, and chin rest.
3) For measurement in manual mode, 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.
4) When the other eye needs to be guided with the fix light in chin-rest
measurement mode, place the lamp on the chin rest in front of the
other eye.
