The description mentions "digital signal processing algorithms" for peak validation and probe alignment, which are standard signal processing techniques, not necessarily AI/ML. There is no mention of AI, ML, deep learning, or related concepts in the document.
No.
The device is used for measurement and calculation (diagnosis/assessment), not for treating or rehabilitating a medical condition.
Yes
The device measures AL, ACD, and LT of the human eye, which are used to calculate the optical power of an IOL, and these measurements are crucial for diagnosing and planning cataract surgery.
No
The device description explicitly states it is a "USB plug-in device that uses A-Mode, pulsed echo ultrasound technology," indicating it includes hardware components for ultrasound measurement.
Based on the provided information, the DGH 6000 is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- DGH 6000 Function: The DGH 6000 directly measures physical characteristics of the human eye (axial length, anterior chamber depth, lens thickness) using ultrasound technology. It does not analyze samples taken from the body.
- Intended Use: The intended use clearly states the measurement of parts of the human eye and calculation of IOL power, all of which are direct measurements and calculations related to the living eye.
Therefore, the DGH 6000 falls under the category of a medical device used for direct measurement and diagnosis in vivo, not an in vitro diagnostic.

Intended Use / Indications for Use
The intended use of the DGH 6000 is the measurement of AL, ACD, LT of the human eye. The DGH 6000 is also intended to calculate the optical power of an IOL that is to be implanted during cataract surgery. The DGH 6000 is intended to be used solely by qualified medical professionals. Clinical consideration and judgment should be applied when using the DGH 6000.

§ 892.1560 Ultrasonic pulsed echo imaging system.
(a)
Identification. An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(b)
Classification. Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

Description of Device:
The DGH 6000 A-Scan is a USB plug-in device that uses A-Mode, pulsed echo ultrasound technology to measure the axial length (AL), anterior chamber depth (ACD), and lens thickness (LT) of the human eye. The device includes formulas to calculate the implanted IOL power, using the axial length measurement.
Quantel Medical AXIS II Ultrasonic Biometer (K000554)
DGH 3000A Ultrasonic A-Scan (K872726)
Intended Use of the Device:
The intended use of the DGH 6000 is the measurement of AL, ACD, LT of the human eye. The DGH 6000 is also intended to calculate the optical power of an IOL that is to be implanted during cataract surgery. The DGH 6000 is intended to be used solely by qualified medical professionals. Clinical consideration and judgment should be applied when using the DGH 6000.
Technological Characteristics:
Axial length (AL), anterior chamber depth (ACD), and lens thickness (LT) measurements are obtained using the same technology as the predicate device, DGH 3000A. The technology is based on ultrasonic pulse echo technology, whereby short bursts of ultrasonic energy are transmitted and the resulting echoes are captured, amplified, filtered and processed. Specific time distances in the captured echo peaks are then measured and converted into distance information. Digital signal processing algorithms validate individual peaks and proper probe alignment. The resulting measurements and waveforms are then displayed on a PC monitor for the medical (ophthalmic) professional user. In addition, the software assists the user in calculating replacement intraocular lens values based on established IOL calculation formulas.

- . NEMA Standard Publication UD-3 2004: Standard for Real-Time Display of Thermal and Mechanical Acoustic Output Indices on Diagnostic Ultrasound Equipment.
(B) Clinical Tests
Since the DGH 6000 Scanmate-A uses the same technology as existing devices, clinical tests are not required.
Conclusions:
We have reviewed the results of the performance tests and have determined that the DGH 6000 is substantially equivalent, in safety and efficacy, to the legally marketed predicate device.

Dear Mr. Devine:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
This determination of substantial equivalence applies to the following transducers intended for use with the DGH 6000 Scanmate A, as described in your premarket notification:
Transducer Model Number
DGH 6000
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.
4
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
This letter will allow you to begin marketing your device as described in your premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus permits your device to proceed to market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please go to http://www.fda.gov/AboutFDA/CentersOffices/CDRHOffices/ucm115809.htm for the Center for Devices and Radiological Health's (CDRH's) Office of Compliance. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to
http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.
