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.
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.
