Introduction

WARNING! Healthcare professionals must inform patients not to modify or discontinue
their treatment plan without receiving instructions from the healthcare professional.
WARNING! Patients must not modify or discontinue their treatment plan without
receiving guidance from a healthcare professional.
WARNING! The tonometer is intended for personal use only and measuring other
people, animals, or objects is forbidden.
WARNING! If you need help in using the iCare HOME2 tonometer, contact your
healthcare professional.
PRECAUTION! Do not cover the eye recognition transmitters or sensor during the
measurement, for example with your fingers. Keep your hand, hair, and objects such as
pillows away from the temple side of your eye, as they produce an infrared reflection
that causes an error.
PRECAUTION! Read this manual carefully, as it contains important information about
using and servicing the tonometer.
PRECAUTION! Report any serious incidents related to the tonometer to your competent
health authority and the manufacturer or the manufacturer's representative.
The iCare software system consists of the following:
• iCare HOME2 tonometer
• iCare CLINIC, a browser-based software service with which the healthcare
professional and patient can view the measurement data
• iCare CLINIC On-premises, a version of iCare CLINIC that can be installed
on a hospital's or clinic's own server. With iCare CLINIC On-premises,
the measurements cannot be viewed from outside of the hospital or clinic,
or uploaded from outside, only from within hospital or clinic using the
iCare EXPORT.
• iCare PATIENT2 mobile application with which the patient and healthcare
professionals can view measurement data and transfer it to the iCare
CLINIC cloud service
• iCare EXPORT computer software with which the patients and healthcare
professionals can view the measurement data and transfer it into the
iCare CLINIC cloud service or iCare CLINIC On-premises
See chapter "12 iCare software system" for details.
If a patient's tonometer is not registered to a healthcare professional's
iCare CLINIC account, the patient can store their measurement data to a
private account in the iCare CLOUD service. For information on how to set
up a private account, read the Getting started guide in the tonometer's
carrying case.
With the iCare HOME2 tonometer, you can measure your eye pressure.
During the measurement, the tonometer's probe gently touches your eye six
times. After the six successful measurements, the tonometer calculates your
eye pressure and stores it in the tonometer's memory. The device history
shows the 100 most recent measurement results.
If your healthcare professional instructed you to measure both eyes, you can
use the same probe for both. After you have taken the measurements, place
the probe back in its container and dispose of it in a mixed waste bin. Use a
new, unused probe when you take a measurement the next time.
You can measure your eye pressure when you are sitting, standing, or lying
down. The tonometer includes infrared eye recognition sensors to identify
which eye, right or left, you are measuring.
After the measurement, you can transfer the measurement data to
iCare CLINIC using your computer or mobile device.

Familiarize yourself thoroughly with the tonometer, software, and the
operational procedures before use.

Information on intraocular pressure

The normal eye pressure ranges from 10 to 20 mmHg (1). The risk for
glaucoma increases if the eye pressure is above this range. In normal tension
glaucoma, the optic nerve is damaged even though the eye pressure is not
very high. The optimal target pressure in glaucoma and ocular hypertension
needs to be defined case by case. Ask your healthcare professional for
your target eye pressures. Agree when you need to contact your healthcare
professional about your eye pressure measurement results.
Follow your healthcare professional's instructions on the frequency of
measurements. Unless otherwise instructed, the recommended frequency
of measurements is 3-6 times a day. Keep a record of your eye pressure
for your healthcare professional. A single measurement does not provide
accurate information on your eye pressure level. You need to take and record
several measurements over time. Try to measure your eye pressure at the
same times each day for consistency.
An elevated eye pressure as well as fluctuations in the eye pressure are
underlying risk factors for glaucoma (2,3). When you measure your eye
pressure in a variety of situations and at different times of the day, you and
your healthcare professional get a comprehensive view of the changes in
your eye pressure and the effectiveness of your medication.
