PREDICATE DEVICE Icare ic100 tonometer (type TA011), K153694 This predicate has not been subject to a design-related recall. #### IV. INDICATIONS FOR USE / INTENDED USE "The Icare ic200 tonometer is intended to be used for the measurement of intraocular pressure of the human eye." The intended use of the Icare ic200 (type TA031) as well as the method used by the clinician to obtain a measurement remain unchanged from the predicate tonometer Icare ic100 (TA011) by this design modification. {4}------------------------------------------------ ## V. DEVICE DESCRIPTION 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). #### Software The Icare ic200 (TA031) Tonometer has embedded software utilizing a microcontroller. The software performs the following functions: - Provides a user interface utilizing the user operable button and an OLED . display to control the measurement cycle - Provides control to LED Probe base light - Controls the probe's movement ● - Calculates the intraocular pressure from the probe speed during impact ● - Handles possible error conditions, such as recognizing if probe didn't contact . cornea or if the speed of the probe is abnormal - . Calculates the standard deviation of the measurements during the measurement cycle and instructs user to repeat the measurement if the variability is unacceptable {5}------------------------------------------------ - . Provides time setting to the internal clock - Retrieves the serial number for identification of the device - Stores measurement history in an external flash memory IC. - . Controls the device hardware based on device position (inclination) In addition to the embedded software, the Icare ic200 includes an OTS (Off the Shelf) Bluetooth® module. which enables wireless communication. Icare proprietary software Icare EXPORT and Icare CLINIC are designed to work with the Icare ic200 as software accessory. Icare EXPORT is intended for transferring measurement data from Icare tonometers into the Icare CLINIC software's database. Icare CLINIC performs the following functions: - Stores measurement data received from Icare devices ● - Shows and prints charts based on the measurement data - Exports measurement data from Icare CLINIC to external systems ● - Imports measurement data from external systems - Maintains patient database and measurement history ● #### Calibration As is the case for the predicate device, the design and principle of operation of the Icare ic200 (TA031) tonometer is such that maintenance calibration is not required. The tonometer does not include any mechanical or electrical parts subject to wear, which would cause an out of tolerance condition. Only the probe base, which as an accessory, can be replaced or cleaned by user as instructed in the Instructions for Use. ## Environment of use The Icare ic200 tonometer is intended to be used in professional healthcare environment. ## VI.

Modifications of external device structure and user interface are secondary modifications, which support this primary modification and improve the usability of the device. Wireless measurement result transfer via Bluetooth® is a state-of-the-art feature, which has been added as a separate option that can also be disabled. Wireless connection doesn't affect the clinical use, measurement software, primary result display or any features related to the clinical safety and effectiveness of the device. ## VII. PERFORMANCE TESTING The following performance testing has been conducted to confirm that the performance and safety aspects of the modified tonometer Icare ic200 are substantially equivalent with the Icare ic100 cleared for marketing under 510(k) K153694. #### Software Verification and Validation Testing The software used in the Icare ic200 (TA031) is based on predicate device Icare ic100 software and the modifications have been developed and maintained per the requirements IEC 62304 Medical device software - Software life cycle processes. Software verification and validation testing were conducted, and documentation was generated 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 was considered to cause "moderate" level of concern, since a failure or latent flaw in the software could lead to an erroneous diagnosis or a delay in delivery of appropriate medical care. Bluetooth® software (OTS) included in Icare ic200 was considered to cause "minor" level of concern, since the software does not influence the intended use or clinical functions of the device and the measurement result display enabled by the Bluetooth® is additional to the primary measurement result display method. {8}------------------------------------------------ The Icare CLINIC and EXPORT software are accessories to ic200 and therefore they are also considered to have "moderate" level of concern. They have been developed and maintained per the requirements of IEC 62304 standard and software verification and validation testing has been conducted and documented per FDA guidance "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices". #### Electrical safety and electromagnetic compatibility (EMC) Electrical safety and EMC testing were conducted on the Icare ic200 tonometer. The device complies with the IEC 60601-1standard for electrical safety and the IEC 60601-1-2 standard for EMC. #### Bench performance testing Icare ic200 tonometer performance in IOP measurement was compared to predicate device Icare ic 100 tonometer performance. The testing was performed with a simulated IOP model, which was also used during the original predicate device submission (K153694). - Icare ic200 met the predetermined acceptance criteria for accuracy and bias over the . measurement range ensuring substantial equivalence to the previously cleared Icare ic100 tonometer. - Repeatability of the Icare ic200 tonometer was assessed in bench test. Test was done . by measuring a manometrically controlled test cornea. Test pressures (7, 10, 20, 30, 40 and 50 mmHg) covered the specified measurement range of the Icare ic200 tonometer. To assess repeatability, 10 measurements were performed with the test tonometer in three different angles (0, 45 and 90 degrees). Icare ic200 tonometer demonstrated an agreement with true manometric pressure, R-squared values being over 99.7 %, regardless the angle of measurement (0, 45 or 90 degrees). On average, the Icare ic200 tonometer underestimated the pressure by 0.33 mmHg with respect to true manometric pressure, standard deviation being 0.82 mmHg. - Reproducibility was assessed by test in which two operators performed three . measurements with three different ic200 units in each measurement setup, resulting 162 measurements per operator. The mean difference between operators was 0.10 mmHg with standard deviation of 0.98 mmHg. The R-squared value in regression analysis was over 99.5%, which indicates high reproducibility across the operators and across the devices. Please be advised that bench testing conditions do not cover all the error sources within a clinical setting and thus higher variability is expected in clinical use. {9}------------------------------------------------ #### Clinical performance testing Clinical study was to compare the agreement and precision of the intraocular pressure (IOP) results measured by the Icare ic200 tonometer device with the Goldmann Applanation Tonometer (GAT) reference device per ANSI Z80.10:2014 "Ophthalmic Instruments - Tonometers" standard (in accordance with FDA's extent of recognition). In addition, GAT and Tonopen Avia were compared with Icare ic200 in the sitting position and Tonopen Avia and Perkins in the supine position. Possible individual patient discomfort and potential device complications or adverse events were recorded. No adverse events (including corneal abrasions) were reported in this study. Per the ANSI Z80.10 standard the differences between ic200 and GAT measurements overall and within three IOP subgroups are summarized in Table 1 below. | Group | N (eyes) | Outside ±5 mmHg | |-------------------------------------------|----------|--------------------| | GAT group = low ≤ 16 mmHg | 45 | 0/45 (0.0%) | | GAT group = medium > 16 to <23 mmHg | 67 | 2/67 (3.0%) | | GAT group = high ≥ 23 mmHg | 40 | 0/40 (0.0%) | | Overall | 152 | 2/152 (1.3%) | Table 1. Differences between ic200 and GAT, overall and within IOP subgroups The descriptive statistics (n, Mean, SD, Median, Min, Max) for the IOP measurements from ic200, GAT and Tonopen Avia in sitting position are summarized in Table 2 below. Table 2.

Summary of IOP measurements ic200, Tonopen Avia and Perkins in supine position The results of the study demonstrated that Icare ic200 is safe and performed as intended and conformed with the ANSI Z80.10 standard compared to GAT. #### Conclusions The overall performance testing (bench and clinical) demonstrated that the Icare ic200 provides equivalent performance as the predicate device Icare ic100. #### VIII. SUBSTANTIAL EQUIVALENCE The Icare ic200 tonometer uses the same operating principle found in the predicate device and in all rebound type tonometers. The intended use of the Icare ic200 as well as the method used by the clinician to obtain a measurement remain unchanged by the modifications. The technological comparison demonstrates that the use of Icare ic200 does not raise additional questions of safety and effectiveness. In conclusion, it has been demonstrated that the Icare ic200 (TA031) tonometer is substantially equivalent in fundamental design, technology, function, device materials, packaging, sterilization (of probes), operating principle, performance and intended use/ indication for use as the previously cleared Icare ic100 tonometer described in the original 510(k) submission (K153694).
