WARNING!
Federal (US) law restricts this device to sale by or on the order of a physician or properly
licensed practitioner.
WARNING!
Use only the original and certified probes made by the manufacturer. The probes are for
single-use (one per testing session only). Each testing session is defined by one successful
measurement in both eyes (or only one eye measurement if indicated). Use probes taken
only from the intact, original packaging. The manufacturer cannot guarantee sterility of
the probe once the seal is compromised. Re-sterilization or re-use of the probe could
result in incorrect measurement values, in the breakdown of the probe, cross-
contamination of bacteria or viruses, and infection of the eye. Re-sterilization or re-use
will void all responsibilities and liabilities of the manufacturer concerning the safety and
effectiveness of the tonometer.
WARNING!
The probe should be replaced if it contacts or is suspected of having contacted the
eyelashes or eyelid such as might occur during a blink.
WARNING!
Use of accessories, transducers and cables other than those specified or provided by the
manufacturer of this equipment could result in increased electromagnetic emissions or
decreased electromagnetic immunity of this equipment and result in improper operation.
WARNING!
Use of this equipment adjacent to or stacked with other equipment should be avoided
because it could result in improper operation. If such use is necessary, this equipment
and the other equipment should be observed to verify that they are operating normally.
PRECAUTION!
•The patient should be instructed to thoroughly wash and dry their hands with soap
and a clean towel prior to handling the probe.
•When you have opened the package, check for any external damage or faults,
particularly for damage to the case. If you suspect that there is something wrong
with the tonometer, contact the dealer who sold the tonometer to you.
•Use the tonometer only for measuring intraocular pressure. Any other use is
improper and the manufacturer is not liable for any damage arising from improper
use, or for the consequences of such use.
•Never open the casing of the tonometer, except for the battery compartment.
•Never allow the tonometer to get wet.
•Do not use the tonometer near flammable substances, including flammable
anesthetic agents.

PRECAUTION!
•The tonometer conforms to EMC requirements (IEC 60601-1-2), but interference
may occur within the tonometer if used near (<1m) a device causing high intensity
electromagnetic emissions, such as a cellular phone. Although the tonometer’s own
electromagnetic emissions are well below the levels permitted by the relevant standards, they
may cause interference in other, nearby devices, for example sensitive sensors.
•If you do not use the tonometer for a long time, remove the batteries, as they may leak.
•Be sure to dispose of the single-use probes properly (for example, in a bin for metal waste).
•Batteries, packaging materials and probe bases must be disposed of according to local
regulations.
•Make sure you use batteries with built-in PTC protection, for example Energizer Lithium Photo
123 3V CR123A.
•Do not cover the eye recognition transmitters or sensor during the measurement, for example
with fingers. Keep your hand, hair etc. and objects such as pillows away from the temple side of
your eye, as they produce an infrared reflection that causes an error.
•The tonometer turns off automatically after 3 minutes if it is not used.
•Do not carry out any other service procedures than those described in the chapters 10-12. Leave
all other service and repairs to the manufacturer or a certified service center.
•Update the tonometer’s time to your local time. It is done automatically by performing the steps
1 and 2 under section 8. Reading the measurement data.
•Icare HOME tonometer is not intended for routine clinical use.
•As the Icare HOME is intended to acquire serial measurements of intraocular pressure over an
extended period of time, individual IOP measurements are not to be considered separate from
their associated IOP curves. This IOP measurement tool is an adjunct to the standard of care
and does not replace the conventional methods used to diagnose and manage patients nor
should it alter the follow-up schedule otherwise indicated for a particular patient.
•Bench testing of the Icare HOME tonometer on model eyes showed that there was no impact on
probe function and performance with 30 repeated uses within a single testing session. The
impact on probe function and performance when the probe is repeatedly used over 30 times is
unknown.

6. INTRODUCTION
The Icare HOME tonometer is a hand-held device for self-use.
The tonometer uses the rebound method. A small and light single-use probe makes
contact with the eye very briefly. The tonometer measures the deceleration of the
probe and the rebound time, and calculates the IOP from these parameters.
A measurement sequence includes six measurements. The probe moves to
the cornea and back during every measurement. As a result, after the six
measurements the tonometer calculates the final IOP and stores it with other
information in the tonometer’s memory, including date, time, eye identification
(right or left) and measurement quality.
The Icare HOME tonometer can record over one thousand measurement results.
You can copy the recorded measurement information to a PC through a USB cable.

PRECAUTION!
Do not cover the eye recognition transmitters or sensor during the measurement, for example
with ngers. Keep your hand, hair etc. and objects such as pillows away from the temple side
of your eye, as they produce an infrared reection that causes an error.
The tonometer includes an automatic eye recognition system that identies which
eye, right or left, you are measuring. The system has two infrared LED transmitters
just below the probe base and one infrared LED sensor above the probe base, as
in the gure below. The right-hand transmitter sends invisible infrared light to the
right and the left-hand transmitter to the left. The infrared light reects from your
nose to the sensor. The sensor knows from which transmitter the reected infrared
light came, and thus which eye you are measuring. The resulting eye indication is
included in the data that you can transfer to a PC, as described in the section 9.
