Intended use
The “plusoptiX S12” is used for the early detection of visual disorders (preventative eye
care). These visual disorders can cause permanent loss of vision in an eye (amblyopia) if
they are not discovered and treated in the early years.
To detect visual disorders, the “plusoptiX S12” measures the sphere, cylinder, axis, line of
vision and pupil size of both eyes at the same time. Using these measurement values, the
spherical equivalent, gaze symmetry and interpupillary distance are calculated. All
measurement values are compared with age-dependent referral criteria. “Refer” is
automatically displayed as a precautionary result for every patient requiring an
ophthalmologist appointment.
Note:
Preventative eye care with the “plusoptiX S12” does not replace the eye
examination carried out by an ophthalmologist. An ophthalmologist remains the
only one who can interpret the measurement values and establish a diagnosis.
The measurement values must not be used directly to prescribe glasses or
contact lenses.
All children who are not already being treated by an ophthalmologist should undergo a
preventative eye care examination. The first preventative eye care examination should be
carried out at the age of one. They should then be repeated regularly, as the eyes can
change during growth and new visual disorders can appear at any time. All children with a
“Refer” result from the preventative eye care examination should be referred for an eye
examination with an ophthalmologist.
Note:
False-positive and false-negative results can occur in any type of preventative
examination.

3 Learning about the „plusoptiX S12“
The “plusoptiX S12” is made up of the device with a child-friendly smiley face.
During a measurement, the “plusoptiX S12” records a series of images. To ensure children
look into the camera during the measurement, the “plusoptiX S12” plays a warble sound.
The speaker, the camera lens and the LEDS needed to light the images are located behind
the black protective screen with the smiley. This smiley helps to keep the child’s attention.
Attention:
If a child is not looking at the camera lens in the middle behind the hexagon
during the measurement, this can lead to a cancellation of the measurement or
incorrect measured values of the visual symmetry. Therefore do not use any
other external fixation aids!
Attention:
If you need to put the device on its rear side, e.g. to insert or replace the
rechargeable batteries, please place a soft cloth under the device.
Note:
To prevent the protective shield from becoming dirty, we recommend that you do
not touch it. If the protective shield does become dirty, read chapter 10
“Maintenance, calibration, service and guarantee”for cleaning instructions.

7.2 Ordering new Measurements
To order new measurements, we require certain information about your device. This
information can be found in the area “Loading Measurements” in the lower left area of the
Pay-Per-Use Management (see Figure 6).
Connect a SD card and activate the button to create the order fax (1). Confirm this with the
green tick (2), in order to save an order fax to the SD card. This contains all details
necessary for an order.
You can also have your address automatically printed on the order fax. Create a text file with
a maximum of 5 lines and name it "surgeryaddress.txt”. Copy the file to the directory “/db” of
a USB stick. As soon as you connect the USB stick to the running “plusoptiX S12”, your
address is loaded automatically. After loading, the text file is automatically deleted on the
USB stick. To overwrite the stored address, a new text file must merely be saved in the
directory “/db” of the USB-memory stick.
You can:
- send the order fax per mail to the mail address specified on the order fax.
- print out the order fax on your network- or workplace printer and send it per fax to the fax
number specified on the order fax. To do this you must first open the PDF file of the order
fax from your workplace computer. There are two different access possibilities available:
Connect SD card stick directly to the workplace computer.
Start Windows Explorer or Apple Finder and open the order fax to be printed.
You can print out the order fax on any optional printer connected with your
network- or workplace computer.
Manual network access (WLAN)
File access at URL: \\px12-xxxx\pdf (Windows Explorer)
smb://px12-xxxx/pdf (Apple Finder)
The place holder “xxxx” stands for the last four digits of the serial number.
If the workplace computer indicates the error message “Access denied”,
restart Windows Explorer or Apple Finder.
Note:
The saving of the order fax takes a few seconds and is dependent on the SD
card. If the SD card is removed too soon or the URL called up too early, the PDF-
file is not yet saved.
If the SD card has been removed too soon, it must be plugged into the “plusoptiX
S12” again, in order to save the order fax on the SD card.
If accessed too early, the URL must be called up again.
Plusoptix will then send you a load code, with which you can load your credits. Enter this
load code in the gray field “Load Code” (3) using the keypad integrated in the screen view or
with the help of a connected USB keyboard (see chapter 3.3 “Connection the USB keyboard
and mouse (optional)”) and then confirm this with the green tick (2) in the navigation bar. The
new measurements will be immediately displayed in the field “Loaded” and at the right in the
header.
1) 2) 3)

Page 15/25
8 Preparing the measurement area
The measurement is carried out using infrared light, which is also contained in
sunlight and in the light of bulbs and halogen spotlights, for example. This infrared
light is invisible to the human eye and completely safe.
To obtain correct measurement values, it is important to avoid disruptive sources
of infrared light in the examination room. Close curtains, roller blinds and shutters
to block out the sun’s rays.
Turn off all light sources that produce heat. This does not mean that the
examination room should be dark. Cold light sources, such as energy saving bulbs
and neon lights, do not affect the measurement values.
More information about preparing the measurement area can be found in short manual 2 on
our homepage (www.plusoptix.com), under support.
9 Performing measurements
The “plusoptiX S12” measures both eyes at the same time (binocular) in 0.5 seconds from a
distance of one meter. This means that even infants with a short attention span can be
measured from the age of 5 months. The simultaneous measurement of both eyes also
facilitates a reliable comparison of both eyes’ measurement values. More information about
performing a measurement can be found in short manual 2 on our homepage
(www.plusoptix.com), under support.
A measurement can be performed anonymously or by indicating patient data. More
information about entering or retrieving patient data can be found in short manual 4 on our
homepage (www.plusoptix.com), under support.
Note:
The “plusoptiX S12R” has no internal patient database. After the measurement a
single line to enter patient data will be portrayed, where you can fill in individual
patient data. These data will also be portrayed in the measurement report and on the
self-adhesive label.

9.1 Preconditions for a successful measurement
a) The measuring distance is correct:
The measuring distance must be between 95 cm and 105 cm. Check whether the
camera image on the screen is in focus. You must be able to see the individual hairs on
the eyelids or the eyelashes clearly on the camera image.
b) Der Patient schaut auf die Kameralinse:
The “plusoptiX S12” and the eyes of the patient must be aligned with one another. The
patient must look at the nose of the smiley face. For this reason, an attention grabbing
warble sound is emitted at the beginning of the measurement.
Note:
The attention span of toddlers is very short. Take advantage of the fact that the
examination room is unknown to the toddler. The attention-grabbing "Warble"
sound in this unknown environment always arouses interest. Avoid lengthy
conversation with parents before the measurement.
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 gaze symmetry. For this reason, do not use any other external
fixation aids!
c) Both of the patient’s pupils should be completely visible:
The pupils must not be covered by eyelids, eyelashes or hair, for example. Check
whether both pupils can be seen completely on the screen and whether they are
encircled in green.
d) The pupil diameters must be between 4 and 8 mm:
Note:
If a red error message is displayed, an action recommendation is also displayed
below it. Please read supplementary short manual 9 on our homepage
(www.plusoptix.com), under support.

Page 17/25
9.2 Selecting the referral criteria
Touch the button to choose the referral criteria (1) in the settings. There are five validated
groups of referral criteria to choose from (see Figure 9: Selecting the referral criteria).
These five groups are called ROC 1, ROC 2, ROC 3, ROC 4 and ROC 5. Each of these
groups defines different, age-dependent thresholds, which lead to a “Refer” preventive test
result. These five groups are shown along a schematic ROC (Receiver Operating
Characteristic) curve. Select a group by touching the relevant button (2) and confirm by
touching the green checkmark (3).
9.3 Starting the measurement and adjusting the “plusoptiX S12”
After you have set the time and date, the home page will be displayed every time you turn
the “plusoptiX S12” on again.
Figure 10: Home page
Select an age group by touching the appropriate age range (see Figure 10: Home page).
You must select the age group (1) in order to ensure the measurement values of the patient
are compared with the correct age-specific referral criteria (see Chapter 9.2 “Selecting the
referral criteria”).

Figure 11: Selection of the age group
- Hold the “plusoptiX S12” at eye level to the child, about 1.2 meters away. The measuring
distance is one meter, but it requires practice to correctly estimate this measuring distance
in one go. It is easier to hold the “plusoptiX S12” somewhat further away at the start of the
measurement and then slowly move it towards the child.
Note:
The screen is fixed at a 45° angle to the camera axis. Tilt your wrists downwards
to align the camera.
By touching the flashing “GO” button (1) or pressing the trigger, you will start the camera and
a warble sound will be heard. You can now see the camera image on the screen.
Note:
A started measurement can be aborted by touching the screen.
- Adjust the “plusoptiX S12” so that both eyes can be seen on the screen and then slowly
move the “plusoptiX S12” towards the patient until the camera image can be seen in high-
definition on the screen. Firstly, the pupils will be surrounded by white squares (the image
is still very blurred), then with red and finally with green circles (see Figure 13).

9.4 Checking and documenting the measurement results
As space on the screen is limited, the measurement results are spread across a total of two
(plusoptiX S12R), or three screens (plusoptiX S12C) respectively. After the measurement,
you will first see the “camera image” results page. By touching the appropriate button in the
middle of the navigation bar, you can access each of the three results pages.
More information about checking and documenting the measurement results can be found in
short manual 3, 5 and 6 on our homepage (www.plusoptix.com), under support.
Figure 13: Detecting the correct measuring distance
Figure 14: Overview of the results pages
The image is blurry and two red bars will be displayed next to the camera image. As the
measuring distance is too great, you can see the head of the patient virtually in its entirety.
Move the “plusoptiX S12” towards the patient until the camera image can be seen in high-
definition on the screen and both pupils are encircled in green.
The image is blurry and two red bars will be displayed next to the camera image. As the
measuring distance is too small, the eyes can be seen on the screen. Move the
“plusoptiX S12” away from the patient until the camera image can be seen in high-
definition on the screen and both pupils are encircled in green.
The image can be seen in high-definition on the screen, the bars are green and both pupils
are encircled in green. As soon as both pupils are surrounded by a green circle, the line
between the pupils turns green and another warble sound can be heard. The
“plusoptiX S12” is now a metre away from the child and the measurement begins
automatically. A “ping” sound signalises the end of the measurement.
