The iCare ST500 tonometer is a device intended to be used for the intraocular pressure of the human eye. The iCare ST500 tonometer is intended to be used by healthcare professionals.

The iCare ST500 tonometer is based on a patented, induction-based rebound method, which allows intraocular pressure (IOP) to be measured by a healthcare professional accurately, rapidly and without an anesthetic. The iCare ST500 tonometer measures a patient's IOP while he or she is in an upright (sitting) position. It is attached to a slit lamp with the ST500 Adapter, making it easy to use during a standard eye exam. This tonometer is designed only for use with a slit lamp not as a handheld device. The tonometer is compatible with most of the common slit lamp models on the market. The tonometer system consists of the iCare ST500 tonometer (together with ST500 Remote and ST500 Adapter, ST500 SmartCradle and a medical power supply used with ST500 SmartCradle), and a compatible printer and slit lamp. With the iCare rebound measurement method, a miniature, lightweight, single-use probe is launched in a direction perpendicular to the surface of the center of the cornea of the eye. The probe is composed of a medical grade plastic tip and a metal shaft. The metal shaft is magnetized prior to the measurement. During the measurement, the probe can be considered to act like a moving magnet that induces an electric signal in the surrounding coil allowing for a highly accurate measurement of the probe's motion. After launching. the probe briefly contacts the cornea and bounces back. The tonometer records multiple parameters covering the motion of the probe, including deceleration, and rebound time. Using a proprietary algorithm, the device can calculate the eye's IOP. The displayed IOP reading is derived from the results from a sequence of six individual probe rebounds. The displayed IOP measurement is also stored in the tonometer's memory for later retrieval. The iCare ST500 tonometer has a rechargeable battery and can be charged in the ST500 SmartCradle powered by a medical power supply. The tonometer can be operated by using the buttons on the tonometer or by using the wireless battery-operated ST500 Remote control.

The iCare IC200 tonometer is intended to be used for the measurement of intraocular pressure of the human eye.

The iCare IC200 tonometer (model TA031) is a hand-held, battery-operated device which measures intraocular pressure (IOP) without the need for topical anaesthesia by rebound tonometry. The tonometer is to be used by a healthcare professional. The tonometer uses the rebound method. A small and light, sterile, single-use probe makes brief contact with the eye. The device measures the deceleration of the probe and the rebound time and calculates the IOP from these parameters. Deceleration of the probe is slower at low IOP compared to high IOP. The measurement method, the IOP measurement algorithm and rebound technology (including disposable probe) are identical with the predicate device. iCare IC200 tonometer can obtain IOP measurements in all angles between horizontal and supine directions. External design has not been modified. The user interface menu has been updated to contain a Quick Measure mode. The new Quick Measure feature is used to measure patient's IOP with fewer rebound measurements and faster measurement cycle. Quick Measure takes two or three rebound measurements; two if both results are within 2 mmHg and third if the difference between the first two measurements is greater than 2 mmHg.

The iCare HOME2 tonometer is a prescription device intended as an adjunct to the routine clinical monitoring of intraocular pressure (IOP) of adult patients.

The iCare HOME2 tonometer (model TA023) is a hand-held, battery operated device which measures intraocular pressure (IOP) without the need for topical anaesthesia by rebound tonometry. The tonometer is to be used by the patients themselves. The tonometer uses the rebound method. A small and light, sterile, single-use probe makes brief contact with the eye. The device measures the deceleration of the probe and the rebound time and calculates the IOP from these parameters. Deceleration of the probe is slower at low IOP compared to high IOP. The measurement method, the IOP measurement algorithm and rebound technology (including disposable probe) are identical with the predicate device. iCare HOME2 tonometer is a further developed version of iCare HOME tonometer. It features enhancements such as possibility to measure IOP in any angle between 0° and 90° (horizontal to supine patient position) and possibility for wireless measurement result transfer to mobile device or to PC. External design and user interface have been modified for better usability and ergonomics. The measurement data can be uploaded to iCare CLINIC for further analysis using either iCare EXPORT (desktop application) or iCare PATIENT2 (mobile application). iCare PATIENT2 is a mobile app intended for transferring eye pressure measurement data from the iCare tonometer to the iCare CLINIC cloud service or an external system. The app displays the eye pressure measurement results and helps in glaucoma management. It is indicated for use by healthcare professionals and patients. Measurement results can be transferred to iCare CLINIC with either through a Bluetooth connection or by connecting the USB C type connector to the device and mobile phone, depending on the user's mobile phone operating system.

The Icare HOME tonometer is a prescription device intended as an adjunct to the routine clinical monitoring of intraocular pressure (IOP) of adult patients.

The Icare HOME tonometer is a home-use handheld, battery operated device that measures the intraocular pressure (IOP) without the need for topical anaesthesia. It is for prescription use only and to be used under the supervision of a healthcare professional. The device is intended to be used by patients at home. The tonometer uses the rebound method. A small and light, sterile, single-use probe makes brief contact with the eye. The device measures the deceleration of the probe and the rebound time and calculates the IOP from these parameters. Deceleration of the probe is slower at low IOP compared to high IOP. The measurement sequence includes six measurements. The probe moves to the cornea and back during every measurement. The tonometer stores information on every complete measurement sequence of six measurements. The stored information includes the calculated final IOP, time and date of the measurement, identification of the eye (right or left) and the quality level of the measurement (i.e. the standard deviation of the six individual measurements). The measurement data can be uploaded to Icare CLINIC for further analysis using either Icare EXPORT (desktop application) or Icare PATIENT (mobile application). Icare CLINIC is a browser-based software designed for managing patient information and the IOP measurement data.

The Icare ic200 tonometer is intended to be used for the measurement of intraocular pressure of the human eye.

The Icare ic200 (TA031) tonometer is a hand-held, battery operated device, which measures intraocular pressure (IOP) without the need for topical anesthesia. The Icare ic200 tonometer measures the IOP by utilizing the rebound method, where a small (1.8 mm diameter), light (26.5 mg) probe makes brief contact with the eve. The Icare ic200 probes are sterile (gamma sterilized), single-use accessories of the device. All other accessories of the Icare ic200 are non-sterile and do not have direct patient contact. Icare ic200 allows IOP measurement of patients in all positions between sitting position (direction of probe movement 0°) and supine position (direction of probe movement 90°). Identical to the predicate device, the Icare ic200 (TA031) tonometer records the speed of the probe upon initiation of a measurement sequence. When the moving probe contacts the cornea, the probe decelerates at a rate which depends on the intraocular pressure. The tonometer measures the deceleration of the magnetized probe and the rebound time during contact with the eye and calculates the IOP from these parameters. A single measurement sequence includes six measurements. After the six measurements are completed, the tonometer calculates the final IOP and the result is provided on the display. JOP measurement result can be transferred to printer or to a PC via Bluetooth® connection. The measurement method, the IOP measurement algorithm and rebound technology (including sterile, single-use probe) of Icare ic200 are identical to the predicate device Icare ic100 (TA011, K153694).

The Icare HOME tonometer is a prescription device intended as an adjunct to the routine clinical monitoring of intraocular pressure (IOP) of adult patients.

The Icare HOME Tonometer is a home-use handheld, battery operated device. The Icare HOME tonometer technology is based on the previously cleared Icare tonometer model TA011 (K063873), which has been commercially distributed in the United States, Europe and many other countries worldwide. The measurement method, the measurement algorithm and technology of the two models are identical and both models use the same disposable probe tip. The Icare HOME tonometer utilizes the rebound method to measure intraocular pressure. A small (1.8 mm diameter), light (26.5 mg), sterile, single-use probe tip makes brief and gentle contact with the eye. The device measures the deceleration of the magnetized probe and the rebound time during contact with the eye and calculates the IOP from these parameters. Deceleration of the probe is slower at low IOP compared to high IOP. A single measurement sequence includes six measurements for both measurement modes. The probe moves to the cornea and returns to the neutral position during each of the six measurements. 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 i.e., the standard deviation of the six individual measurements. The Icare HOME Tonometer can record over one thousand measurement results. The physician can transfer this recorded measurement information to a computer through a USB cable.
