The summary describes standard image processing, perimetry, and fixation tracking techniques, with no mention of AI or ML algorithms. The software level of concern is "Moderate," which is less likely to involve complex AI/ML.
No
The device is primarily for diagnosis and measurement (color retinography, fixation examination, microperimetry) with a rehabilitative "support" function, rather than directly providing therapy. The "visual rehabilitation" section explicitly states it is used "to support the fixation training for patient," implying it aids rather than executes the therapy itself.
Yes
The device is indicated for "Color retinography," "Fixation examiner," and "Fundus-related microperimetry," which are all diagnostic functions. It measures "visual sensitivity of a specified area on the fundus" and "captures color fundus images," displaying an "overlaid with the retinal sensitivity mapping" for "fundus-image-correlated evaluation." It also measures "fixation and determine the preferred retinal locus," indicating its role in assessing a patient's condition.
No
The device description clearly outlines hardware components such as an LCD projector, response button, LCD screen, illumination LEDs (infrared and xenon flash lamp), and a color CCD camera. While it includes software for processing and display, it is integrated into a physical device with significant hardware functionality.
Based on the provided information, the MICROPERIMETER MP-3 and MICROPERIMETER MP-3 Type S are not In Vitro Diagnostic (IVD) devices.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- Device Function: The MICROPERIMETER MP-3 and MP-3 Type S directly interact with the patient's eye (fundus) to measure visual sensitivity, examine fixation, capture fundus images, and support visual rehabilitation. They do not analyze specimens taken from the body.
- Intended Use: The stated intended uses (Color retinography, Fixation examiner, Fundus-related microperimetry, Visual rehabilitation) all involve direct interaction with the patient's eye and assessment of visual function and structure.
Therefore, this device falls under the category of ophthalmic devices used for diagnostic and therapeutic purposes related to the eye, not IVD devices.

510(k) Summary
Visual rehabilitation is a collective name of Fundus-related microperimetry, Feedback exam, They are used to support the fixation training for patient.
Feedback exam: similar function with the Fixation exam. The same as those in Fixation exam, Feedback exam, and Fixation exam, and differ only in the following characteristics: in the Feedback exam, a sound is heard and the appearance of the fixation target changes when the patient's vision inside the circle specified by the operator (TRL Trained[tarqet] Retinal Locus, which the patient cannot see).
Intended Use/Indications for Use
The MICROPERIMETER MP-3 and MICROPERIMETER MP-3 Type S are indicated for use as: Color retinography Fixation examiner Fundus-related microperimetry
Visual rehabilitation
Indications for Use Comparison
The indications for use are identical.
Technological Comparison
The Microperimeter MP-3 and MP-3 Type S are 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 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 0.003 asb (Type S), while the predicate device allowed only 4 asb. The minimum stimulus luminance is 4.4 asb (4 asb - white - 34 dB mode) and 35.4 asb (31.4 asb white on white 34 dB mode) and for Type S 0.0042 asb (0.003 asb - white on white - 24 dB mode), while the predicate device allows only 8 asb. The maximum stimulus luminance is 10,031.4 asb, while the predicate device allows only 404 asb.
These larger ranges don't raise any safety issue. Compliances with both the light hazard recognized standards ISO 15004-1 and ANSI Z80.36, and voluntary ISO 12866 standards are documented.
Differences in Visual Rehabilitation
In the predicate device the bio-feedback audible signal consists of an internitting sound, with frequency increasing the doser the new PRL is to (center of) the central target until a continuous sound is heard. The subject device allows both continuous sound and music when the exam is successfully completed.
The subject device allows user to change the position of the Stimulation Pattern, while the predicate doesn't allow. The design modifications outlined in this Traditional 510(k) premarket notification do not (1) affect the intendication for use or (2) alter the fundamental scientific technology of the device. The proposed Microperimeter MP-3 and MP-3 Type S share 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 proposed Microperimeter MP-3 is substantially equivalent to MP-1MICRO PERIMETER (K061768) .
Testing in Support of Substantial Equivalence Determination
We have verified and validated that the Micropermeter MP-3 and MP-3 Type S meet its functions and performance requirements, and complies with applicable international standards (IEC 60601-1-2, ISO 15004-1, ANSI Z80.36, ISO 12866, ISO 10940).
As mentioned, all necessary bench testing was conducted on the addition of the proposed Microperimeter MP-3 and MP-3 Type S, 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 60601-1-2, ISO 15004-1, ANSI Z80.36, ISO 12866, ISO 10940) and it is safe as the predicate device.
