Intended Use

MiiS Horus Scope DPT 100 is a digital portable tonometer used to measure intraocular pressure of eyeball.

Device Story

MiiS Horus Scope DPT 100 is a battery-powered, digital portable non-contact tonometer. It uses white LED illumination and a CMOS sensor to capture images of the eye. The device measures intraocular pressure (range 7-55 mmHg) via air-puff technology. Operated by clinicians, the device features a 3.5" capacitive LCD touch panel and keypad for adjustments and viewing. Data can be transferred to a PC via USB 2.0 interface or stored on an SD card. By providing non-invasive pressure measurements, the device assists clinicians in monitoring ocular health and managing conditions related to intraocular pressure.

Clinical Evidence

Clinical performance testing was conducted comparing the MiiS DPT 100 to the Keeler Digital Applanation Tonometer (D-KAT) in accordance with ISO 8612:2009 and ANSI Z80.10-2014. Bench testing confirmed the device met acceptance criteria for operating range (7-55 mmHg), accuracy, repeatability, and reproducibility using a manometer-controlled model.

Technological Characteristics

Portable non-contact tonometer; Li-ion rechargeable battery; white LED illumination; CMOS sensor; 3.5" capacitive LCD touch panel; USB 2.0 connectivity; SD card storage. Complies with IEC 60601-1 (safety), IEC 60601-1-2 (EMC), ISO 15004-2 (optical hazards, Group 1), and ISO 10993-5/10 (biocompatibility for chin rest).

Indications for Use

Indicated for measuring intraocular pressure of the eyeball in patients requiring tonometry.

Regulatory Classification

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.

The circular design consists of concentric rings of alternating shades of gray and white, creating a visual effect similar to a bullseye. The word "MiiS" is written in a bold, sans-serif font, with a horizontal line underneath it. The entire logo is enclosed within a rounded square with a blue border.

Image /page/6/Picture/2 description: The image shows three different medical devices used for eye examinations. The first device has a square screen and a handle on the side. The second device is handheld and has a display screen on top. The third device is a larger, stationary machine with a screen and a joystick.

## 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.
- 2. Software verification and validation testing was done according to IEC 62304.
- 3. 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.
- 4. 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.

The target design consists of concentric circles alternating between black, white, and gray shades. The word "MiiS" is written in a bold, sans-serif font and is underlined with a blue line. The entire logo is enclosed within a rounded rectangle with a white background.

- 5. 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.
- 6. 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.
