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.
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.
