The summary does not mention any AI or ML terms, image processing, or data sets typically associated with AI/ML development. The device description focuses on standard laser technology and control modes.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device is for "photocoagulating ocular tissues of the treatment of diseases of the eye," indicating its use in treating medical conditions.
No
The device is intended for photocoagulation and treatment of eye diseases, which are therapeutic procedures, not diagnostic ones.
No
The device description explicitly lists hardware components such as a laser console, touch control panel, applicators, foot switch, and instrument table. The performance studies also include biocompatibility, laser safety, electrical safety, and bench testing, which are relevant to hardware components.
Based on the provided information, the VISULAS green device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is used for "photocoagulating ocular tissues of the treatment of diseases of the eye." This is a therapeutic procedure performed directly on the patient's body (in vivo).
- Device Description: The description details a laser system used for treating ocular tissue. This aligns with a therapeutic device, not a device used to examine specimens from the human body (in vitro).
- Lack of IVD Characteristics: There is no mention of the device being used to test samples like blood, urine, tissue, etc., which are characteristic of IVD devices.
IVD devices are used to examine specimens from the human body to provide information for diagnosis, monitoring, or screening. The VISULAS green is a therapeutic device used to treat conditions within the eye.

Summary of Performance Studies
Biocompatibility Testing: Testing performed aligns with current recognized standards and meets or exceeds testing performed on the predicate device. Biocompatibility testing demonstrated equivalency between the subject device and the predicate device.
Laser safety, electrical safety and electromagnetic compatibility (EMC): VISULAS green was evaluated against ANSI/AAMI ES60601-1:2005/(R) 2012, ANSI Z80.36-2016, IEC 60601-1-2:2014, IEC 60825-1:2007, IEC 60601-2-22:2012, and IEC 62133: 2012, and was found to comply with these requirements.
Software Verification and Validation Testing: The software is considered a "Major" level of concern. Verification and validation testing was conducted as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." Verification and validation demonstrated that the product works as designed.
Bench Testing: Non-clinical system testing provided an evaluation of the system relevant to each of the system specifications. The functional and system level testing showed that the system met the defined specifications. ZEISS demonstrated non-clinical equivalency between the subject device and the predicate device.

Dear Tanesha Bland:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and 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 (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

The VISULAS green and predicate devices are both intended as ophthalmic lasers for photocoagulation. The indications for use are within the same intended use as the predicate devices and do not raise different questions of safety and effectiveness.
The primary differences between the subject device, VISULAS green (K232051), and the predicate device, VISULAS green (K181682), are listed in the following table with corresponding justification as to why the changes do not affect the safety and effectiveness of the subject device.

The VISULAS green subject device and the predicate laser systems have minor parameter differences but share the same fundamental principle of operation:
Photocoagulation: Continuous wave operation in which thermal energy created by the absorption of the laser energy by the ocular tissue is causing coagulation.
The subject VISULAS green is substantially equivalent to the predicate laser systems presented in the 510(k) premarket notification in terms of indications for use and technological characteristics. Differences between subject device and predicate devices do not raise any new issues of safety or effectiveness.

7. SUMMARY OF STUDIES
Biocompatibility Testing
Biocompatibility testing was performed on the appropriate components of the subject device. The testing performed aligns with current recognized standards and meets or exceeds testing performed on the predicate device. Biocompatibility testing demonstrated equivalency between the subject device and the predicate device.
Laser safety, electrical safety and electromagnetic compatibility (ENC)
VISULAS green was evaluated against the following requirements and was found to comply with:
- · ANSI/AAMI ES60601-1:2005/(R) 2012
- ANSI Z80.36-2016
- · IEC 60601-1-2:2014
- · IEC 60825-1:2007
- IEC 60601-2-22:2012
- · IEC 62133: 2012
Software Verification and Validation Testing
The software of this device is considered as a "Major" level of concern. Software verification and validation testing was conducted, and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." Verification and validation of VISULAS green demonstrated that the product works as designed.
Bench Testing
Non-clinical system testing provided an evaluation of the system relevant to each of the system specifications. The functional and system level testing showed that the system met the defined specifications. ZEISS demonstrated non-clinical equivalency between the subject device and the predicate device.
Animal Testing
Not applicable. Animal studies are not necessary to establish the substantial equivalence of this device.
Clinical Data
Not applicable. Clinical studies are not necessary to establish the substantial equivalence of this device.
CONCLUSION 8.
The VISULAS green is substantially equivalent to the predicate device, VISULAS green (K181682).
The VISULAS green is similar in technological characteristics, performance, principles of operation, and has identical indications for use as the predicate device. Any differences between the proposed device and the predicate devices do not raise any new issues of safety or effectiveness. Thus, the VISULAS green is substantially equivalent to the predicate devices.
