Patient Positioning & Alignment
The AT550 features a unique auto-alignment system that enables the instrument to
align itself and follow the patient’s eye movement. This innovative system makes the
whole measurement process quicker and more comfortable for the patient.
t The patient should be seated comfortably on the patient side of the
instrument.
t To facilitate patient alignment during the measurement process, we
recommend the instrument be positioned in such a way that it encourages
the patient to lean forward and slightly down onto the forehead
rest. This will cause the patient to gaze slightly downward, reducing
problems associated with eyelids or eyelashes during the alignment and
measurement process (see Figures A & B).

below:
1. Ask the patient to look at the end of the nosepiece and to view the green
xation light.
2. Instruct the patient to lean against the forehead rest while looking at the
green xation light.
3. Point to the side you want the patient to lean against, making sure the patient
does not place his/her head in the middle of the forehead rest, because the
patient will not see the xation light properly. Once in the proper position,
conrm that the patient can still see the light.
NOTE: If the patient has diculty nding the xation light, the patient may
need to move up or down on the forehead rest.
