The device store images to a SD card and have connectivity towards PC. The device uses an USB 2.0 interface to transfer data or picture to PC when connected.

The operation method of the device is described step by step in the attachment A1 "User manual". There is a graphical user interface color TFT display and keypad that is used for making adjustments before and during measure intraocular pressure of eyeball. Its' measure rang is 7-55 mmHg.

AI/ML Overview

The MiiS Horus Scope DPT 100 is a digital portable tonometer used to measure intraocular pressure of the eyeball. The following information details its acceptance criteria and the study proving its performance.

1. Table of Acceptance Criteria and Reported Device Performance

Performance Metric	Acceptance Criteria (from ISO 8612:2009 and ANSI Z80.10-2014)	Reported Device Performance (MiiS DPT 100)
Operating Range	Not explicitly stated in the provided text as a numerical range, but implied to be sufficient for clinical use. Predicates have 0-60 mmHg.	7-55 mmHg
Accuracy	Not explicitly quantified in the provided text, but implied to meet standards.	Met the acceptance criteria for accuracy with a manometer-controlled model.
Repeatability	Not explicitly quantified in the provided text, but implied to meet standards.	Met the acceptance criteria for repeatability with a manometer-controlled model.
Reproducibility	Not explicitly quantified in the provided text, but implied to meet standards.	Met the acceptance criteria for reproducibility with a manometer-controlled model.
Compliance with Ophthalmic Standards	Meets requirements of ISO 15004-2:2007 (for optical hazards, Group 1 classification).	Met all requirements of ISO 15004-2:2007, classified as Group 1 for optical hazards.
Biocompatibility	Meets ISO 10993-5:2009 and ISO 10993-10:2010 standards for contact materials.	Met ISO 10993-5:2009 and ISO 10993-10:2010 standards for the chin rest holder material.

Note: The document primarily focuses on overall compliance with standards rather than specific numerical targets for all performance metrics. For "Accuracy," "Repeatability," and "Reproducibility," the text states "The units under test met the acceptance criteria," indicating successful conformance without providing the specific numerical criteria or results.

2. Sample Size Used for the Test Set and Data Provenance

Sample Size for Human Eye Clinical Performance Test: The document does not specify the exact number of human subjects or measurements used in the clinical performance test. It only states that "Data was collected" in comparison to the predicate device.
Data Provenance: Not explicitly stated. The manufacturer is based in Taiwan (R.O.C.), but the country of origin for the clinical test data is not provided. The study appears to be prospective as it's a "Clinical Performance Test" conducted to evaluate the device against a predicate.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

The document does not mention the use of experts to establish ground truth for the test set. Instead, it relies on a predicate device (Goldmann applanation tonometry (GAT) Keeler Digital Applanation Tonometer (D-KAT) (K133234)) as the comparative standard for the human eye clinical performance test.

4. Adjudication Method

Not applicable. The study compares the device's measurements directly to a predicate device, not against an adjudicated expert consensus.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No, a multi-reader multi-case (MRMC) comparative effectiveness study was not conducted or described. The study focused on the device's technical performance and its direct comparison to a predicate tonometer. There is no mention of human readers or AI assistance.

6. Standalone Performance

Yes, a standalone performance evaluation of the algorithm (or device in general, as it's a tonometer, not specifically an AI algorithm for image interpretation) was conducted. The "bench test" evaluated the operating range, accuracy, repeatability, and reproducibility with a manometer-controlled model. The "Clinical Performance Test" also assessed the device's standalone performance by comparing its measurements to a predicate device on human eyes.

7. Type of Ground Truth Used

For bench testing: A manometer-controlled model was used as the ground truth for evaluating operating range, accuracy, repeatability, and reproducibility.
For clinical performance testing: Measurements from a Goldmann applanation tonometry (GAT) Keeler Digital Applanation Tonometer (D-KAT) (K133234) served as the comparative standard (ground truth) for human eye measurements. Goldmann Applanation Tonometry (GAT) is widely considered the gold standard for intraocular pressure measurement.

8. Sample Size for the Training Set

Not applicable. The MiiS Horus Scope DPT 100 is presented as a tonometer device for direct measurement of intraocular pressure, not an AI-based system that requires a "training set" in the context of machine learning. The document does not mention any AI components or machine learning models that would necessitate a training set.

9. How the Ground Truth for the Training Set Was Established

Not applicable, as there is no mention of a training set for an AI-based system.

Substantial Equivalence Discussion

Similarities:

MiiS Horus scope DPT 100 and predicate device, Reichert PT100 Portable (Tonometer) have the same intended use. Both devices have same specifications, such as contact area, working distance, power source and input voltage. DPT 100 has similar specifications to Reichert PT100 Portable (Tonometer), such as the measurement range, measurement scale, weight, dimension and connection interface.
-MiiS Horus scope DPT 100 and predicate device, Topcon CT-80 Computerized Tonometer have the same intended use. DPT 100 has similar specifications to Topcon CT-80 Computerized Tonometer, such as the working distance, measurement range, measurement scale and input voltage.

Differences:

The major differences are inspection window. MiiS Horus scope DPT 100 has 3.5" -Capacitive LCD touch panel. But, Reichert, Ltd. PT100 use eyepiece to observe.
-The major differences between MiiS Horus scope DPT 100 and Topcon CT-80 Computerized Tonometer are weight, dimension, inspection window, interface, power source and product appearance.
-These variants don't impact on device safety and effectiveness.

Non-clinical and Clinical Tests

The following data were provided in support of the substantial equivalence determination:

1. EMC and electrical safety testing were conducted on the DPT 100. The device complies with IEC/EN 60601-1-2:2014/2015 for EMC and IEC/EN 60601-1:2005/2006+A1:2012/ 2013 for Safety.
1. Software verification and validation testing was done according to IEC 62304.
1. Risk management: DPT 100 was evaluated according to ISO 14971:2007 and EN ISO 14971:2012. All risks have been reduced to safe levels thus there is no conflict between risk and benefit.
1. Tests for ophthalmic products: DPT 100 was tested in accordance with ISO 15004-2:2007 standards and was found to meet all requirements of the standards. For optical hazards was classified to Group 1.

1. Biocompatibility: The contact part to patient is the holder of chin rest CR100. The holder material was tested in accordance with ISO10993-5:2009 and ISO10993-10:2010 standards.
1. Tests for tonometer:

The performance of MiiS DPT 100 has been evaluated in bench test. The units under test met the acceptance criteria of the operating range, accuracy, repeatability and reproducibility with a manometer-controlled model. We also do Clinical Performance Test, and found a Goldmann applanation tonometry (GAT) Keeler Digital Applanation Tonometer (D-KAT) (K133234) to do the human eye Clinical performance test compared to MiiS DPT 100. Data was collected according to ISO 8612:2009 and ANSI Z80.10-2014 "Ophthalmic Instruments – Tonometers" (in accordance with FDA's extent of recognition) with the following results.

Conclusion

Substantial equivalence comparison and bench performance tests support the conclusion of substantial equivalence of MiiS Horus scope DPT 100 to the predicate devices.

Regulation Number and Section

§ 886.1930 Tonometer and accessories.

(a)
Identification. A tonometer and accessories is a manual device intended to measure intraocular pressure by applying a known force on the globe of the eye and measuring the amount of indentation produced (Schiotz type) or to measure intraocular tension by applanation (applying a small flat disk to the cornea). Accessories for the device may include a tonometer calibrator or a tonograph recording system. The device is intended for use in the diagnosis of glaucoma.(b)
Classification. Class II.
