Ask the patient the following question:
“ Look at the test, tell me what the small characters are that you can make out, and read them aloud (or
describe them) .”
If the patient manages to make out 3 out of 5 optotypes on the same line of acuity, the level of
acuity is considered as achieved.
Save the visual acuity value. You can save this value:
• On the console keyboard, by pressing on the key located in the middle of the 4 arrows.
Only for the logarithmic scales and rational scale if a line or a symbol is isolated.
• On the touch screen, by pressing on the acuity value appearing in the display area.
The value of the visual acuity of patient (OD, OG or BINO) changes into blue and is saved in the
section “Patient Data”, in the memory “Visual Acuity”.
It appears in the dial on the right of the screen.
