3.5.5.3 Move the machine away from the patient and focus the eye
Now, while the patient is looking at the center of the house in the stimulus, move
the machine as far as possible from the patient's eye and try, as best as possible,
to center the pupil on the coordinate axis superimposed on the live image.
During this step:
•
Do not pay attention to whether or not the eye appears focused on the live
image.
•
Let the patient know that they can blink as many times as they want, since
no measurement is being captured yet.
