Device Story

Microperimeter MP-3 is an ophthalmic diagnostic device used in clinical settings to assess retinal function. It captures 45-degree color fundus images using a color CCD camera and xenon flash, performs fixation examination by tracking eye position over time, and conducts fundus-related microperimetry to map visual sensitivity. The device features automated alignment and focusing using infrared LEDs. During microperimetry, an internal LCD projector displays stimuli and fixation targets; the patient responds via a button. The device computes response signals and displays results on an LCD. Clinicians use these outputs to evaluate fixation stability and visual sensitivity, aiding in the diagnosis and management of retinal conditions. The device offers wider background and stimulus luminance ranges compared to its predecessor, enhancing diagnostic flexibility.

Clinical Evidence

Bench testing only. Verification and validation testing confirmed the device meets functional specifications and performance requirements. Compliance with international standards (IEC 60601-1, IEC 60601-1-2, ISO 15004-1, ISO 15004-2, ISO 12866, ISO 10940) was documented.

Technological Characteristics

Ophthalmic diagnostic system; utilizes infrared LEDs for alignment/focusing and xenon flash for imaging. Features a color CCD camera and internal LCD projector for stimulus display. Connectivity includes LCD display for output. Complies with IEC 60601-1 (electrical safety), IEC 60601-1-2 (EMC), and ISO 15004-1/2 and ISO 12866 (light hazard).

Indications for Use

Indicated for color retinography, fixation examination, and fundus-related microperimetry in patients requiring ophthalmic imaging and visual sensitivity mapping.

#### Color retinography

This function allows a 45° image of the efthe eye fundus to be acquired without the need for a mydriatic agent. Auto alignment is performed while observing on the LCD, the front of the patient's eve illuminated by the eve front illumination LED (infrared light). After the alignment is roughly complete, the mode automatically changes to the fundus observation mode. The fundus of the patient's eye is illuminated by the fundus illumination LED (infrared light). After alignment and focusing are automatically performed on the fundus, white light from the xenon flash lamp is emitted on the fundus. The light reflected from the fundus is captured by the built-in color CCD camera for fundus image capture.

#### Fixation examiner

This function allows recording of the patient's fixation position changes in time and plotting of them onto a stable retinal image, acquired at the beginning of the exam. It is therefore an accurate survey of the stability of fixation itself.

# Fundus-related microperimetry

This function allows a visual sensitivity mapping that can be displayed using static perimetry principle. Stimuli and a fixation target are displayed by the built-in LCD projector. While focusing on the fixation target, the patient presses the response button to indicate that they saw a stimulus projected at the location and light intensity specified by the internal measurement program or the operator. The patient's response signals are computed by the device and measurement results are displayed on the LCD.

### Substantial Equivalence

The Microperimeter MP-3is substantially equivalent to the predicate device with regard to design, function, technological characteristics, intended use and performance characteristics.

The differences between the proposed and predicate device and justifications as to why these differences do not raise safety or efficacy concerns are as follows.

#### Differences in Color retinography

The subject device may perform alignment and focusing automatically, while the predicate device performs the same operation only manually.

#### Differences in Fixation examiner

The subject device may perform alignment and focusing automatically, while the predicate device performs the same operation only manually. The exam is performed in the same way, but the subject device has improved the result display.

#### Differences in Fundus-related microperimetry

The subject device may perform alignment and focusing automatically, while the predicate device performs the same operation only manually.

The background luminance can be set at 31.4 asb or 4 asb, while the predicate device allowed only 4 asb. The maximum stimulus luminance is 10,031.4asb, while the predicate device allows only 404asb. These larger ranges don't raise any safety issue.Compliances with both the light hazard recognized standards ISO 15004-1 and ISO 15004-2, and voluntary ISO 12866 standards are documented in Appendix 2.8 and 2.9.

The design modifications outlined in this Special 510(k) premarket notification do not (1) affect the intended use or the indication for use or (2) alter the fundamental scientific technology of the device. The proposed Microperimeter MP-3shares the equivalent indications for use, the same technological characteristics and the same principle of operation as the predicate devices. Therefore, based on the similarities between the devices, the

proposedMicroperimeter MP-3 is substantially equivalent to MP-1MICRO PERIMETER (K 023719).

# Testing in Support of Substantial Equivalence Determination

We have verified and validated that the Microperimeter MP-3meets its functional specifications and performance requirements, and complies with applicable international standards (IEC 60601-1, IEC 60601-1-2, ISO 15004-1, ISO 15004-2,ISO 12866, ISO 10940).

As mentioned, all necessary bench testing was conducted on the modifications, the addition of the proposed Microperimeter MP-3, to support a determination of substantial equivalence to the predicate device.

# Summary of Safety and Effectiveness

All the necessary safety tests were performed and documented. The results demonstrate that the subject device complies with applicable international standards (IEC 60601-1, IEC 60601-1-2, ISO 15004-1, ISO 15004-2,ISO 12866, ISO 10940) and it is safe as the predicate device. All the necessary performance tests in support of substantial equivalence determination were conducted. The tests demonstrate that the subject device is effective and performs as well as the predicate device. The minor differences between the devices do not raise any new issues of safety or efficacy.

Thus the proposed Microperimeter MP-3 is substantially equivalent to the predicate device.
