KERATOMETER MEASURING TECHNIQUE
Placing Patient in Instrument
Prior to putting the patient in the headrest
of the instrument the chin and head rests
should be wiped with an alcohol swab or a
tissue placed on the chin rest.
The patient should be seated comfortably
and the instrument adjusted to the height
of the patient. The patient is asked to rest
their chin in the chin rest and to bring their
forehead tight against the headrest. A
common mistake is for the patient to be
too low (instrument too high) and for the
patient's forehead to be away from the
headrest.
The patient should be asked to grasp the
instrument just in front of the chinrest so
that they will stay as still as possible
during the measurement.
