OPERATING PROCEDURE: Uncorrected Visual Acuity Measurement (UCVA)
5
Ask the patient whether they can read the pre-
sented chart.
The presented chart is displayed on the screen.
6
According to the patient’s response, press the chart
up button or chart down button to change
the VA chart.
7
Repeat Steps 5 to 6 to determine the limit of the VA value (uncorrected visual acuity:
UCVA) that the patient can read.
To save the VA value lower than 0.1, press the chart up button with the VA chart set to 0.1.
“<0.1” is displayed on the screen.
8
Switch the eye to be measured and perform uncorrected visual acuity measurement
for the other eye in the same manner.
9
Press the return button to exit from uncorrected visual acuity measurement mode
and return to the AR (AR/KM) measurement screen.
The VA value of the displayed chart is saved as an uncorrected VA value (UCVA).

Chart up
The patient could not read the chart.
A VA chart one level lower is presented.
Chart down
The patient could read the chart.
A VA chart one level higher is presented.
• Because the VA value is saved at the time of returning to the AR (AR/KM) measurement screen from
the uncorrected visual acuity measurement screen (VA TEST), do not change the chart after deter-
mining the limit of the VA value.
