Introduction
This documentation is designed to enhance your understanding of the
capabilities of the Pulsair EasyEye by providing comprehensive and easy to
follow descriptions and instructions.
The names of buttons are presented in bold typeface.
Cross-references are presented in bold, italic typeface.
Unless stated to the contrary, positions and directions such as left, right,
front and rear are given with respect to the unit when viewed from the
front.
The fundamental basis upon which the Pulsair EasyEye operates are
discussed below.
Accuracy and Calibration
The Pulsair EasyEye calibration has undergone extensive clinical trials to
ensure that the instrument is reliable and accurate.
Pressure Variations
It is well known that IOP varies as a result of pulse, respiratory and diurnal
fluctuations. In addition blinking, squeezing, fluid intake, physical activity,
body position and even the direction of gaze can influence IOP.
English
Non-contact Tonometers take an instantaneous measurement that may
vary due to the pulsatile nature of the IOP. By taking four readings a more
accurate indication of IOP can be recorded.
Corneal Response to the Air Pulse
The response of the cornea to the air pulse is known as an event. The
Pulsair EasyEye has been designed to use the gentlest possible air pulse to
achieve good quality events in the majority of eyes.
When a non event or bad event is detected by the Pulsair EasyEye it
displays ER and automatically switches to 30+ mode to create a slightly
higher pressure air pulse for the next reading.
5EP59-50399 Issue D
English
Puls
air
EasyEye
Autoactivation
The Pulsair EasyEye automatically fires a gentle puff of air at the cornea
when the hand unit is correctly aligned with the eye.
Memory
The Pulsair EasyEyes’ memory holds the readings taken, on both eyes, for
a patient, up to a ma ximum of ten readings per eye. The memory is only
cleared when the hand unit is removed from the holster for use on another
patient.
You must review the readings taken for a patient or print a patient record
before the unit is removed from the holster, reviewing and printing can
take place whilst the hand unit is located in the holster.
Warning
Do not use the Pulsair EasyEye near mobile telephones as performance will be
affected. Advise patients to switch mobile telephones off before use.
Warning

Overview of the Hand Unit
Display
The display shows the recorded IOP reading or the averaged IOP reading.
After the first reading is taken the display shows the measured IOP. After
each of the consecutive reading is taken the display shows the average of
the readings taken so far, i.e. the first figure displayed is the actual reading,
the second figure is an average of the first two readings etc., up to a
maximum of ten readings, per eye.
Note: The displayed figure is rounded to the nearest whole number.
The displayed average is based on the actual readings which are taken to
one decimal place. For example, readings of 15.4, 16.3, 14.2 and 16.9 are
averaged by adding them together which equals 62.8 and dividing by the
number of readings taken, 4. This gives a final figure of 15.7, so the display
shows 16.
When all the required readings have been taken the figure displayed is the
IOP that is recorded for the patient.
Review Button
You can review the readings taken at any time:
Press the Review button. The display shows the readings taken in the
order they were taken, the final figure displayed is the cumulative average.
The Pulsair EasyEye’s memory is capable of holding a maximum of ten
individual readings, per eye. When the memory is full no further readings
can be taken.
To clear the memory you can either replace the hand unit in the holster
and remove again or press the Change Eye button.
Right/Left Eye Indicators
The Right/Left Eye Indicators are two arrows located above the Change
Eye button. The illuminated LED indicates the eye that readings are
currently being taken from.
12 EP59-50399 Issue D
Change Eye Button
The Change Eye button is used to change the eye readings are taken on.
The right eye is always selected first by default, when the necessary
number of readings (four is recommended) have been taken press the
Change Eye button. The right eye Indicator extinguishes and the left eye
indicator illuminates, readings can now be taken on the left eye.
When the Change Eye button is pressed QuickPulse, Non Event and
30+ modes are all turned off if they are active.
Non Event and 30+ Indicator
This LED illuminates if the Pulsair EasyEye has registered a non event, bad
event or a reading over 30.
The majority of individuals have IOP’s of 30 mm Hg or less, IOP’s of this
value can be measured with a gentle air pulse. The Pulsair EasyEye has two
pulse modes.
• Normal which can measure IOP’s up to and a little over 30 mm Hg.
• 30+ which can measures IOP’s up to 50 mm Hg.
If the Pulsair EasyEye detects a bad event or a non event it automatically
switches to 30+ mode, this mode is only deactivated when the Change
Eye button is pressed or the unit is returned to the holster.
English
When the bad event or non event occurs between valid readings the
display shows ER and a flashing average. This indicates that the required
minimum of 4 valid readings has not been reached. The Non Event/30+
indicator illuminates, denoting that a slightly stronger air pulse will be used
for the remaining readings. Use the standard method to operate the Pulsair
EasyEye and continue as normal (minimum of four reading recommended).
The most common causes of bad or non events are;
• movement of the eye during the measurement process
• interference of the air pulse by the eyelashes or eyelids if the eyes are
partly closed
• blinking
• eyes which need a slightly stronger pulse of air to achieve applanation
of the cornea.

EasyEye
Eyepiece
The Eyepiece allows the user to view the patients eye and align the
targetting system.
QuickPulse Indicator
This indicator illuminates if the QuickPulse mode is active.
QuickPulse Button
QuickPulse mode may need to be invoked for patients who have corneal
scarring, a high level of astigmatism, or a less reflective eye than normal.
The patient should be asked to blink several times and further readings
attempted before engaging QuickPulse.
The Pulsair EasyEye checks that the eye focus is correct and if so,
produces an air pulse.
Before invoking QuickPulse mode ensure that the correct image is seen
through the eyepiece.
If this is the case and no air pulse occurs, it may be that the particular eye
is less reflective than normal. Press the QuickPulse button. It should now
be easier to obtain a reading. QuickPulse should always be used on post
operative eyes with corneal scarring. QuickPulse mode can be toggled on
and off by pressing the button, the QuickPulse Indicator illuminates if the
mode is active.
The QuickPulse facility should only be used when necessary.
QuickPulse can also aid in training new operators. They may have difficulty
initially in obtaining the correct focus (refer to the pull out instructions,
located underneath the Pulsair EasyEye).
14 EP59-50399 Issue D
Demo Button
In order to reassure the patient you can demonstrate the procedure on the
back of their hand before taking a reading:
• Position the hand unit above the patient's hand and press Demo.
The patient experiences a gentle puff of air.
The Demo button can also help to indicate that the unit is in calibration.
A reading of 30/50 flashes alternatively in the display, when the button is
pressed.
To maintain accuracy, we strongly recommend that the unit is
calibrated annually.
Guidance LED’s
The two green LED’s located on the front of the hand unit act as a guide
when you are lining up the patients eye to take a reading.

Patient Preparation
Before using the Pulsair EasyEye you should make your patient feel at ease
and ensure they are located in an optimum reading location. This is
because apprehension and nervousness may adversely affect the readings
obtained. Follow the points outlined below to achieve this:
• Ask the patient to switch their mobile telephone off if they have one.
• Ensure that the patient is comfortable and in a relaxed position.
• Ask the patient to remove their contact lenses or spectacles if worn
and to blink normally.
In order to reassure the patient, you can demonstrate the procedure on
the back of the patient's hand prior to taking a reading:
• Position the hand unit above the patient's hand and press Demo.
The patient experiences a gentle puff of air.
Before taking a reading you should:
• Ensure the patient and instrument optics are not positioned under
direct lighting (i.e. spot lights or sunlight).
• Ensure the patient’s eyes are fully opened. This helps to prevent
squeezing, where the patient unconsciously tenses their eyelids and
increases IOP.
Throughout the reading process, you should:
• Allow the patient to blink at intervals in order to maintain the corneal
tear film.
Instrument Preparation
1. Plug the power supply in to the Pulsair EasyEye unit.
2. Turn the On/Off switch to l, the status indicator on the front of the
unit luminates green. The display on the hand unit initially shows 8.8,
this demonstrates that all segments of the display are functioning. After
a pause the display shows 0, this indicates that the unit is ready for use.
3. Lift the hand unit from the holster. The unit is supplied with an orange
dust cover which protects the puff tube lens from dust and scratching
whilst in transit. Remove the cover before using the unit.
Note: When the unit is not in use you should replace the dust cover to protect
the puff tube lens.
18 EP59-50399 Issue D
English
When the hand unit is removed from the holster the two green LED’s on
the front illuminate, and the pump starts (an audible tone is emitted). The
pump takes 2 seconds to prime before the unit is operational.
Before using the Pulsair EasyEye press the Demo button to dispel any
minute particles of dust or moisture which may have settled whilst the

11. If the unit does not fire, repeat
step 4-8. See Troubleshooting on
page 28 for more details.
12. After each reading is taken, the display shows the average of all the
readings taken on the eye. When four or more readings have been
taken the average displayed is the IOP recorded for the patient.
13. You can review the readings taken using the Review button. If a non
event or bad event has been detected ER appears in the display when
reviewing.
Note: Each measurement is taken to 1 decimal place but is displayed to the
nearest whole number; 0.5 would be rounded up to 1 mm Hg.
The Next Eye
Once a satisfactory number of readings have been taken on the right eye
press the Change Eye button, the left arrow above the Change Eye
button illuminates. Readings can now be taken on the left eye. See the
Change Eye Indicators and the Change Eye Button on page 13 for
more details.
Printing the Results
The Pulsair EasyEye has a built in printer which prints a patient’s record
once all the readings have been taken.
When the hand unit is returned to the holster the results are automatically
printed if the printer is turned on.
English
If the printer is turned off when the hand unit is returned to the holster,
press the Printer on/off switch to turn the printer on, then press the
Change Eye button on the hand unit (do NOT remove the hand unit from
the holster). The last recorded readings are then printed.
The Pulsair EasyEye memory is cleared when the hand unit is removed
from the holster for use on another patient, therefore if a printout is
required you must turn the printer on before removing the hand unit from
the holster for use on another patient.
To print off another copy of the report press the Change Eye button
whilst the hand unit is in the holster.
If you want to review the patients’ readings you must do this before the
hand unit is removed from the holster for use on another patient.

It is well established that exposure of the eye to intense light for extended
periods poses a risk of retinal photic injury. Many ophthalmic instruments
illuminate the eye with intense light. The clinician must make a risk benefit
judgement about the light intensity to be used in any procedure. The use
of insufficient illumination to examine patients may result in adverse effects
more serious than a retinal photic injury. Further, despite all efforts taken
to minimise the risk of retinal damage, damage may still occur. While no
visible retinal photic lesions have been identified for ophthalmic
instruments, illumination levels have been set to the minimum necessary to
perform the diagnostic function in the Pulsair EasyEye. Young children and
persons with diseased eyes may be at higher risk. The risk may also be
increased if the person being examined has had any exposure with the
same instrument or any other ophthalmic instrument using an intense
visible light source during the previous 24 hours. This will apply
particularly if the eye has been exposed to retinal photography.
The time to reach a potential optical radiation hazard for this device is 120
minutes. This time is for cumulative exposure in a day. It should be noted
that there is a safety factor of about 10 built into the safety guidelines.
Hence for a source with continuous light output, if the exposure time is
120 min, photoretinitis might be expected for an exposure time of
10 x 120 min = 1200 mins (about 20 hours).
