OPERATING PROCEDURE: Operating Procedure and Measurement Method
2)
Bring the main body close to the patient and lightly place the forehead rest against their forehead
(just above the eyebrow of the eye being measured).
Adjust the main body position so that the eye level marker on the main body or occluder is
aligned with the patient's eye. Holding the neck strap tight facilitates stable alignment.
Either eye of the patient may be measured first.
3)
Adjust the main body position so that the
patient’s eye is displayed on the screen.
4)
Confirm that the eye detected is correctly indi-
cated as the one to be measured (R/L) on the
screen.
Normally, the patient’s eye (R/L) is automatically
detected. However, there may be cases where
the eye to be measured (R/L) is not detected
correctly due to the patient’s eye condition.
In such a case, press to select the correct
eye to be measured. When the eye to be mea-
sured is detected automatically, the R/L indica-
tion appears in blue ( / ). When the eye to be measured is set manually, it turns yellow
( / ).
• Error indication for automatic R/L detection
Under certain conditions such as when the patient is wearing
a medical mask, the eye to be measured (R/L) may fail to be
detected correctly. In such a case, / indication
blinks and the error indication appears indicat-
ing that automatic detection has failed. Measurement cannot
be started while the error indication is displayed.
• To enable measurement, perform the following:
•
Remove the medical mask so that the eye to be measured (R/L) is detected.
•
Press to select the eye to be measured.
•
After the eye to be measured is selected manually, the automatic R/L detection will be enabled by deleting the
measurement data, performing the next measurement after printing, or holding down for more than a
second.
