The Fundus Photo Digital Imaging System Model CFD-440 Model is intended to capture, archive, and display digital images of the retina and surrounding areas of the eye.
The Fundus Photo Digital Imaging System Model CFD-440 is an automated imaging device used in conjunction with an ophthalmic fundus camera that requires minimal intervention during the capture of an image. The system is simple to use and requires nominal training for a user to become proficient. Like the predicate device, the Fundus Photo Digital Imaging System Model CFD-440 is an accessory attachment comprised of a digital imaging camera or cameras, computer hardware and software platform intended to capture, store, archive, and display images acquired by the fundus camera.
The provided text describes the Fundus Photo Digital Imaging System Model CFD-440, a device intended to capture, archive, and display digital images of the retina and surrounding areas of the eye. It is an accessory attachment that works with existing ophthalmic fundus cameras. The 510(k) summary focuses on demonstrating substantial equivalence to a predicate device (Zeta Diagnostic Retinal Imaging System, K02216), rather than detailing specific acceptance criteria in terms of clinical performance metrics for the CFD-440 itself.
The document states: "Fundus Photo has performed software verification, validation and performance tests. The results indicate that the Fundus Photo Digital Imaging System Model CFD-440 is substantially equivalent to the software standards exhibited by the predicate device." However, no specific performance metrics, acceptance criteria, or the details of these performance tests are provided beyond this general statement.
Therefore, many of the requested details about acceptance criteria and the study proving the device meets them cannot be extracted from this document, as the submission focuses on demonstrating equivalence in intended use, principles of operation, and technological characteristics rather than quantitative performance against defined acceptance criteria.

Kowa VX-10 is intended for taking pictures of fundus images with mydriatic or without mydriatic.
KOWA VX-10 is a fundus image shooting device which delivers both functions of mydriatic and non-mydriatic, and is capable of shooting with 35mm film, Polaroid film or video camera by replacing the shooting unit in a similar to the predicate devices. The non-mydriatic function uses infrared light as does CANON Cr6-45nm, and alignment and focusing are made from the built-in monitor. A Xenon flash lamp is used for shooting. When mydriatic shooting function is used, visible light is used for observation, and alignment and focusing are made manually by looking into the finder as in FX-500. A Xenon flash lamp is used for shooting. Furthermore, like FX-500, it is capable of fluorescein angiographic fundus shooting.
The provided document is a 510(k) premarket notification for the Kowa VX-10 Fundus Camera. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving that the device meets specific performance acceptance criteria through a clinical study with defined endpoints.
Therefore, the document does not contain the following information:
- A table of acceptance criteria and reported device performance based on a dedicated study.
- Sample sizes used for a test set, data provenance, number of experts for ground truth, or adjudication methods for such a test set.
- Information about a multi-reader multi-case (MRMC) comparative effectiveness study, including effect size.
- Results from a standalone (algorithm only) performance study.
- The type of ground truth used to establish performance metrics (e.g., pathology, outcomes data).
- Sample size for a training set or how ground truth for a training set was established.
Instead, the document focuses on comparing the Kowa VX-10's features, indications for use, and technical specifications to two predicate devices: the CANON Non-Mydriatic Retinal Camera, Model Cr6-45nm, and the KOWA PROFESSIONAL FUNDUS CAMERA MODEL FX-500.
The "study" that proves the Kowa VX-10 meets acceptance criteria, in the context of a 510(k) submission, is a comparison study demonstrating substantial equivalence to predicate devices.

The Discam® Digital Imaging System is intended to be used as an ophthalmic diagnostic tool, which is complimentary to other accepted diagnostic technologies, to track the progress of glaucoma, relative to monitoring changes in the appearance (size and shape) of the Optic Disc.
The Discam® Digital Imaging System is intended to be used to evaluate the Optic Disc, (Optic Nerve Head). It is used in the same fashion as a Fundus camera, except that it's field of view is narrower, in order to focus exclusively on the Optic Disc, (Optic Nerve Head). Evaluation of changes in the size and shape of the Optic Disc, (Optic Nerve Head), is useful in monitoring the progress of patients with Ocular Hypertension, and Glaucoma.
The Discam® Digital Imaging System consists of a CCD Stereo Camera that captures stereo images through an image capture board interfaced with a PC with the minimum requirements mages arough an RAM, 1 GB Hard Disc, 133 MHz CPU, Windows® 95 OS. The CCD stereo camera and housing is mounted on a standard rise and fall table, along with a standard adjustable patient chin rest.
The patient fixates on fixation lights, (fixed LEDs), and the operator views the image on the PC's monitor. Image capture, which is accomplished in 0.2 seconds, is initiated by pushing a iov stick.
Windows® based software allows basic analysis, (measurement of cup and Disc, cup to Disc ratio), of the captured images, using either our optional analysis software, or third party software with user developed algorithms, and data archiving.
The camera measures 370 mm Depth x 360 mm Height x 108 mm Width. It is powered by a switch mode power supply 100 V to 220 V, 50 Hz to 60 Hz.
Illumination is from a 12 Volt 55 Watt Halogen Lamp. There is no flash.

Summary of the "Study" and "Acceptance Criteria" presented in the document:
The "study" conducted for the Discam® Digital Imaging System for its 510(k) submission is primarily a comparison of technological characteristics and intended use to predicate devices, along with non-clinical testing for power and luminance levels.
- Acceptance Criteria (Implicit for Substantial Equivalence): The implicit acceptance criteria are that the Discam® Digital Imaging System's technological characteristics and intended use are similar enough to existing legally marketed predicate devices such that any differences "do not raise any issue of safety or effectiveness." This is evidenced by the "YES" entries in Table 3 for key functionalities, and the justification that differences (like field of view or inclusion/exclusion of confocal laser scanning) don't alter the fundamental safety or effectiveness for its intended use.
- Reported Device Performance:
- Non-Clinical Testing: "The Discam® Digital Imaging System was tested to assure that the power and luminance levels delivered in every mode of operation were within specification." (No specific numerical specifications are given in this summary.)
- Clinical Performance (Reference to Published Data): "Published data indicate that viewing and capturing images of the Fundus and Optic Nerve Head/Optic Disc with Digital Imaging Systems is safe and effective." This is a general statement referencing the body of evidence for similar devices, rather than specific performance data for the Discam® itself.
- Substantial Equivalence: The primary "performance" is its demonstrated substantial equivalence to the listed predicate devices based on the comparison of characteristics. The ability to measure cup and disc parameters is mentioned as a feature, akin to predicate devices.
