OPERATING PROCEDURE: Corrected Visual Acuity Measurement (Subjective Refractive Error Measurement)
5
Repeat Steps 3 to 4 to determine the limit of the VA value 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.
6
Change the corrective lens value if necessary and check the VA value.
●
Changing the corrective lens
The SPH value of the corrective lens can be changed. Adjust the lens power to the most plus power
that provides the best possible vision.
When the SPH has been changed, determine the limit of the
VA value again.
●
Vision comparison function (during distance visual acuity measurement)
The vision of the distance VA chart with the corrected distance values and uncorrected vision (or
vision corrected by LM data) are switched to check the vision difference.
SPH up Changes the SPH value by +0.25.
SPH down Changes the SPH value by -0.25.

• The SPH value of the changed corrective lens is the SPH value of subjective refractive error.
Recall
When LM data is not contained
The distance VA chart is viewed with an uncorrected eye.
Recall
When LM data is contained
A lens for the distance vision as corrected with the patient’s own glasses is
inserted and the distance VA chart is viewed at that distance power.
Corrected distance values Uncorrected vision (0 D) or LM values
