Intended Use

ARGOS is a non-invasive, non-contact biometer based on swept-source optical coherence tomography (SS-OCT). The device is intended to acquire ocular measurements as well as perform calculations to determine the appropriate intraocular lens (IOL) power and type for implantation during intraocular lens placement. ARGOS measures the following 9 parameters: Axial Length, Corneal Thickness, Anterior Chamber Depth, Lens Thickness, K-values (Radii of flattest and steepest meridians), Astigmatism, White-to-white (corneal diameter) and Pupil Size. The Reference Image functionality is intended for use as a preoperative and postoperative image capture tool. It is intended for use by ophthalmologists, physicians, and other eye-care professionals and may only be used under the supervision of a physician.

Device Story

ARGOS is a non-invasive, non-contact optical biometer using swept-source optical coherence tomography (SS-OCT) to measure ocular parameters; device captures axial length, corneal thickness, anterior chamber depth, lens thickness, K-values, astigmatism, white-to-white diameter, and pupil size. It also provides reference image capture for preoperative/postoperative documentation. Operated by ophthalmologists or eye-care professionals in clinical settings; device performs automated calculations for IOL power and type selection. Output includes ocular measurements and reference images, which can be transferred to external image-guided surgical systems to assist in preoperative planning. Device benefits patients by providing precise biometric data necessary for accurate IOL selection during cataract or refractive surgery.

Clinical Evidence

Bench testing only. Performance evaluated against standards including ISO 15004-1, ANSI Z80-36, IEC 60825, and ISO 10343. Hardware validation confirmed accuracy for axial/lateral distance measurements, signal-to-noise ratio, and depth attenuation. Usability engineering performed per IEC 62366. Software verification and validation conducted per FDA guidance. No clinical data presented.

Technological Characteristics

SS-OCT biometer; 1060nm swept laser (3kHz rate); 16-LED video keratometry (850nm); white LED for reference imaging; 630nm fixation LED. Class 1 laser product. Complies with ANSI/AAMI ES 60601-1, IEC 60529 (IP20), ANSI Z80-36, IEC 62471, and ISO 10343. Connectivity to external surgical planning systems (Verion, ORA).

Indications for Use

Indicated for ophthalmologists, physicians, and eye-care professionals to perform non-invasive ocular measurements (axial length, corneal thickness, anterior chamber depth, lens thickness, K-values, astigmatism, white-to-white, pupil size) and IOL power calculations for patients undergoing intraocular lens placement.

Dear Dave Yungvirt:

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 (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 located 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.

{1}------------------------------------------------

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): medical device reporting (reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.html; good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

### 8. Indications for Use:

ARGOS is a non-invasive, non-contact biometer based on swept-source optical coherence tomography (SS-OCT). The device is intended to acquire ocular measurements as well as perform calculations to determine the appropriate intraocular lens (IOL) power and type for implantation during intraocular lens placement. ARGOS measures the following 9 parameters: Axial Length, Corneal Thickness, Anterior Chamber Depth, Lens Thickness, K - values (Radii of flattest and steepest meridians). Astigmatism. White-to-white (corneal diameter) and Pupil Size. The Reference Image functionality is intended for use as a preoperative and postoperative image capture tool.

It is intended for use by ophthalmologists, physicians, and other eye-care professionals and may only be used under the supervision of a physician.

The indications for use are similar between the proposed and predicate ARGOS devices. The proposed ARGOS device has additional reference image functionality as minor difference.

#### 9. Device Descriptive

The ARGOS is substantially equivalent to the predicate device identified previously:

- the ARGOS (Santec Corporation) that was cleared by the FDA on October 2nd, 2015(K150754) as the primary predicate as it has the most similar intended use and characteristics
- the IOLMaster 700 (Carl Zeiss Meditec) that was cleared by the FDA on June 29, ● 2015 (K143275, K170171) as an additional (secondary) predicate to support a new feature of reference image capture on the version of ARGOS in this submission.

The predicate devices are Class 2 devices to premarket notification, as defined per regulation number 21 CFR 886.1850. In addition, the predicate devices have product codes of MXK(ARGOS), and HJO(IOLMaster700).

The version of ARGOS in this submission is a modified version of the Argos cleared under K150754 which is substantially equivalent with regard to intended use, operating principle, function, materials, and energy source. The differences from the predicate ARGOS (K150754) that are subject of this 510(k) submission are:

- An additional feature of reference image capture function ●
- Labeling change including change in the intended use adding the feature of reference . image capture.
- . This image can be transferred to image guided devices in order to support the execution of preoperative plan.
