1 Viewing the measurement results
As space on the screen is limited, the measurement results are spread across a total of two
(plusoptiX A12R), or three screens (plusoptiX A12C and A16) respectively. After the
measurement, you will first see the “measurement values” results page. By touching the
appropriate button in the middle of the navigation bar, you can access each of the three
results pages.
If an anonymous measurement has been taken, a consecutive number will be displayed in
the header. Touch the button with the printer (1) to assign patient data, and/or document the
measurement results (see supplementary short manual 5 and 6).
If the patient data was entered, retrieved or imported from the EMR software before the
measurement, the measurement values are saved automatically.
After viewing the measurement results, you can return to the home page by touching the red
“X” (2) and continue with the operation. You can find more information about this in Chapter
5 “Performing the next measurement“.
Attention:
Following an anonymous measurement, a measurement report is not saved
automatically. As soon as you return to the home page without previously saving,
the measurement report can no longer be saved and printed.
The measurement values and the label, on the other hand, are saved under the
consecutive number of the anonymous measurement. This is shown in the header.
If you take a note of this consecutive number, you can access the measurement
values in the database at a later point in time and print the label.

2 “Camera image” results page
Checking the last camera image means you can detect media opacities, which do not lead to
a measurement interruption.
Note:
After every measurement, check on the “Camera image” results page whether
both pupils are the same lightness and whether structures can be seen within the
pupils. If differences in lightness or structures can be seen, the eye must undergo
a more in-depth examination.
3 “Measurement values” results page
The measurement values are shown separately for the right eye (OD) and the left eye (OS):
If the measurement values are outside the measuring range, “HYP” (for hyperopia) or “MYO”
(for myopia) is displayed as the measurement of the spherical equivalent instead of a
quantitative numerical value.

In addition to the measurement values, a measurement result is displayed:
The measurement has been successfully completed.
The measurement has been aborted inconclusively.
If applicable, a red error message is also displayed:
If a red error message is displayed above the screening result,
please read supplementary short manual 9 “Troubleshooting
malfunctions and measuring interruptions”.
You can see the gaze map for each eye on the left and right edges of the screen. This
illustrates the lines of vision of the eyes during the measurement. As soon as one eye is
focussed more than 10 degrees from the camera (this relates to the inside of both circles),
the points on the gaze map are shown in red. A measurement is then not possible and it will
be interrupted inconclusively.
The Plusoptix Binocular Autorefractor compares the lines of vision of both eyes and
calculates the asymmetry of the lines of vision (ASY). An asymmetry of 0° is equivalent to
perfect symmetry. Asymmetrical lines of vision can be caused by squinting or decentralised
fixation.
Attention:
The displayed asymmetry of the line of vision is not equivalent to the squint angle.
Note:
If a child is not looking at the nose of the smiley face during the measurements,
this can cause a termination of the measurement or inaccurate measurement
values of the asymmetry of the line of vision. For this reason, do not use any other
external fixation aids!

4 “Database” results page (only plusoptiX A12C and A16)
Every successful measurement is automatically documented in the database in chronological
order. Green entries indicate successful measurement results. Inconclusive measurements
are not saved.
After a measurement, the measurement values can be saved as a measurement report and
printed as a label. Touch the printer (1) button in the navigation bar of a results page to
assign patient data, and to send the print job via the infrared interface and save a
measurement report on the SD card (plusoptiX 12) / USB stick (plusoptiX 16). For more
information about the documentation of measurement results, please see supplementary
short manual 5 and 6.
Attention:
All print jobs in print spooler are deleted once device is switched off or switches
off for power saving automatically. Measurement reports saved to a SD-card /
USB stick are not deleted when device is switched off or switches off for power
saving.

5 Performing the next measurement
Attention:
Following an anonymous measurement, a measurement report is not saved
automatically. As soon as you return to the home page without previously saving,
the measurement report can no longer be saved and / or printed.
The measurement values, on the other hand, are saved under a consecutive
number when you take an anonymous measurement. This is shown in the header. If
you take a note of this consecutive number, you can access the measurement
values in the database at a later point in time and print the label.
After a measurement has been completed, irrespective of the “Measurement completed” or
“Measurement aborted!” measuring result, you can:
Measure the same patient again in the pre-selected measurement mode by
pressing the trigger.
Carry out another measurement of the same patient in another measurement
mode (e.g. monocular). To do this, touch the green checkmark in the navigation
bar to carry over the previously entered or selected patient data for the next
measurement.
Return to the home page by touching the red “X” button. Previously entered or
selected patient data is discarded.
