Here are some of the most Frequently Asked Questions about the iCare Tonometer:
IS THE ICARE MEASUREMENT PAINLESS?
Measurement is painless, the light-weight probe touches the cornea momentarily and some patients don’t even notice the measurement.
IS IT POSSIBLE TO HURT THE EYE WITH ICARE?
If the device is used according to the instructions given in user manual, the light-weight probe cannot cause any damage to the patient’s eye.
IS THE ICARE MEASUREMENT RESULT ACCURATE?
Several independent studies prove the accuracy of Icare readings. Extensive bench testing and clinical studies have also been performed to ensure the accuracy and repeatability of measurements.
WHY SIX MEASUREMENTS?
Six measurements are required to provide accurate measurement results by eliminating the variations caused by operator error and heart rate.
DOES ICARE TAKE INTO CONSIDERATION CCT?
Icare tonometer is calibrated for average CCT just like the Goldmann tonometer.
CAN ICARE BE USED WITH CONTACT LENSES?
Yes, but depending on the type of contacts the tonometer readings may be affected by the contact lens. Soft daily disposable lenses (and some soft 2-week or monthly lenses) affect the reading only slightly. Hard contact lenses have a significant effect on the reading and should not be worn when measuring the IOP with Icare tonometer. For most accurate measurement results use of any contact lenses is not recommended.
CAN ICARE BE USED AFTER EYE SURGERY?
Yes, but consider that some of surgeries e.g. LASIK and similar surgeries may change the thickness of the cornea (thinner cornea => lower /false IOP)
CAN ICARE BE USED WHEN THE EYE IS INFECTED?
Yes. Just remember that the probe used to measure the infected eye cannot be used again, even for measuring the non-infected eye of the same patient.
DOES THE CORNEAL SHAPE AND RADIUS INFLUENCE THE IOP READING TAKEN WITH ICARE?
No. The area of contact is so small, that the measurement is not influenced by these aspects.
CAN ANESTHESIA STILL BE USED?
Icare is designed to be used without applying topical anesthetic. For most accurate measurements, we recommend not to apply topical anesthetic when measuring with Icare tonometer. It is possible to measure anesthetized eye but the readings may be affected by the swelling caused by topical anesthetic.
IS IT POSSIBLE TO LOAD PROBE WRONG WAY?
No, it’s not possible to load the probe wrong way. The mechanical design of probe and probe base makes it possible to insert the probe in a correct way.
CAN SAME PROBE BE USED TO MEASURE BOTH EYES OF ONE PATIENT?
Yes, same probe can be used to measure both eyes of one patient if the patient’s eyes are healthy. If the patient has infection in one eye or if there is any doubt that one eye may havea disease that can be transferred from eye to eye, the healthy eye should be measured first. A probe used to measure an infected eye should never be usedto measure a healthy eye. If in doubt, always use a new probe.
HOW PROBES WILL BE DISPOSED OF?
Probes can be disposed of according to the hospital/clinic/practice standard regulations.
DOES ICARE REQUIRE CALIBRATION?
Icare tonometers do not require any maintenance calibration or regular service. The tonometers don’t have any parts that wear out, except for the probe base, which can become dusty or collect some particles that affect the probe movement. The probe base can be changed by the user as described in the user manual. The calibration can be checked if there’s doubt about the measurement results. In such case, you should contact your local dealer/ distributor.
If the tonometer requires service, for example has been dropped to the floor, you should also contact your local dealer/ distributor for further instructions.
