Keeler Pulsair Tonometer User manual

English

Congratulations and thank you for buying the Keeler Pulsair EasyEye, the
only portable, non-contact tonometer. This is an advanced, easy to use
product with a wide range of features, designed to make your life easier.

The Pulsair EasyEye is a result of careful research based on feedback from
users of the Pulsair 3000 and Keeler’s specialist expertise. The features
Keeler have incorporated into the Pulsair EasyEye to maximise
performance and ease of use are:

• Non-contact measurement of Intra-Ocular Pressure (IOP).

• Hand unit operation allowing IOP to be taken on virtually any patient.

• Portability for domiciliary work or easy transport between different
locations, using the rechargeable battery option.

• An automatic averaging system which displays the running average of
readings taken.

• Automatic 30+ mode for reading high IOP.

• A non event or bad event detector to advise when the Pulsair EasyEye
has fired but has been unable to take a reading because, for instance,
the patient has blinked at the wrong moment.

• A built in printer to supply you with a record of the reading taken for
the patient.

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.

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

The Pulsair EasyEye maybe affected by Electro-magnetic interference
(i.e. mobile telephone). If this happens:

• Switch off the offending equipment
or

• Increase the distance between the offending equipment and

EasyEye.

Warning

Eyecaps are designed for training use only. The Eyecaps are disposable and must
only be used once.
