iCare IC200 tonometer (type TA031), K190316
No
The description focuses on the rebound tonometry method, the calculation of IOP from probe deceleration and rebound time, and enhancements related to usability, data transfer, and measurement angle. There is no mention of AI or ML in the device description, intended use, or performance studies. The IOP measurement algorithm is stated to be identical to the predicate device, which also does not mention AI/ML.
No.
The device is intended as an "adjunct to the routine clinical monitoring of intraocular pressure (IOP)," which means it aids in diagnosis and monitoring, not treatment.
Yes
The device is intended as an "adjunct to the routine clinical monitoring of intraocular pressure (IOP)," which means it provides data that aids in the diagnosis and management of a patient's condition. While it doesn't make a diagnosis itself, it provides critical measurements used in a diagnostic process.
No
The device description clearly states it is a "hand-held, battery operated device" that uses a physical probe to measure IOP. While it includes software components (mobile and desktop applications for data transfer and display), the core measurement functionality is performed by hardware.
Based on the provided information, the iCare HOME2 tonometer is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the examination of specimens derived from the human body in order to provide information for diagnostic, monitoring, or compatibility purposes. This typically involves testing substances like blood, urine, tissue, etc., outside of the body.
- iCare HOME2 Function: The iCare HOME2 tonometer directly measures intraocular pressure (IOP) by making brief contact with the eye. It is measuring a physical parameter in vivo (within the living body), not analyzing a specimen in vitro (in a lab setting).
- Intended Use: The intended use is for monitoring intraocular pressure in adult patients as an adjunct to routine clinical monitoring. This is a direct measurement of a physiological parameter, not an analysis of a biological sample.
Therefore, the iCare HOME2 tonometer falls under the category of a medical device, but not specifically an In Vitro Diagnostic device.

Device Description
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.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Bench Performance Testing
Accuracy of the iCare HOME2 tonometer was assessed in a bench test using a manometrically controlled artificial cornea. Manometric pressure was set by using reference tonometer iCare IC200, cleared in K190316.
Repeatability and accuracy testing completed with iCare HOME2 tonometer demonstrated high agreement with manometric pressure and reference tonometers (iCare IC200 and iCare HOME).
Reproducibility test completed with iCare HOME2 tonometer demonstrated high agreement with manometric pressure regardless of the device, operator, or the measurement angle.
Software Verification and Validation Testing
Software verification and validation testing was conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device is considered as a "moderate" level of concern since a failure or latent flaw in the software could directly result in minor injury to the patient or operator.
Clinical Performance Testing
A clinical study was conducted to analyse the variability of the intraocular pressure (IOP) self-measurements with the iCare HOME2 tonometer in comparison to the variability of the IOP measurements with the reference tonometer (iCare IC200) over a wide range of IOP measurement values.
The performance data was obtained from a clinical study. The study was performed at East West Eye Institute, CA 90013, USA, and included 47 patients were found to be eligible for analysis. All the patients were either diagnosed glaucoma patients or 'glaucoma-suspects'. A random eye was selected as the study eye for each patient.
Safety: No adverse events (including corneal abrasions) were recorded in the study population.
Results: The mean paired difference and standard deviation (iCare HOME2 - iCare IC200) were 0.55 mmHg and 2.69 mmHg. The iCare HOME2's variability (difference of repeat measurements) for each patient was ~7.9% for all the IOP ranges.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
The mean paired difference and standard deviation (iCare HOME2 - iCare IC200) were 0.55 mmHg and 2.69 mmHg. The iCare HOME2's variability (difference of repeat measurements) for each patient was ~7.9% for all the IOP ranges.
Overall (N=47): Difference 0.55 (2.69) mmHg. 95% CI for Mean Difference -0.86, -0.23. 95% LOA for Mean Difference -5.82, 4.72.
