No
The summary describes standard image processing and measurement techniques based on the Scheimpflug principle and direct measurement. There is no mention of AI, ML, or any related concepts in the device description, intended use, or performance studies. The "analysis" of images is described as selecting one image by software, which is not indicative of AI/ML.
No.
The device is described as a non-invasive diagnostic system designed to photograph the eye, measure refractive power, and measure central corneal K-values, all of which are diagnostic functions, not therapeutic.
Yes
The "Device Description" section explicitly states that "The PARK 1 is a non-invasive, diagnostic system." Furthermore, its functions, such as taking Scheimpflug images to evaluate corneal thickness, measuring central radii of the cornea, and measuring refractive power, are all diagnostic in nature, providing information about the patient's condition.
No
The device description explicitly states it is a "non-invasive, diagnostic system" that is "stationary and AC powered" and "consists of a measurement unit, built in CPU, head and chin rest and an external power supply." This indicates it is a hardware device with integrated software, not a software-only medical device.
Based on the provided information, the PARK 1 device is not an IVD (In Vitro Diagnostic).
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.
- PARK 1 Function: The PARK 1 directly interacts with the patient's eye to take images and measurements. It does not analyze samples taken from the body.
- Intended Use: The intended use clearly states it's designed to photograph the eye and take measurements of the anterior segment and refractive power. This is a direct measurement on the patient.
- Device Description: The description reinforces that it's a non-invasive system that takes photos and measurements of the eye.
- Anatomical Site: The anatomical site is the anterior segment of the eye, which is a part of the living body being directly examined.
Therefore, the PARK 1 falls under the category of a medical device used for diagnostic purposes, but not specifically an In Vitro Diagnostic device.

Intended Use / Indications for Use
The PARK 1 is designed to photograph the eye and take Scheimpflug images of the anterior segment to evaluate the thickness of the cornea. The implanted keratometer measures the central radii of the cornea. The implanted Ophthalmic Refractometer measures the refractive power of the eye.

Device Description
The PARK 1 is a non-invasive, diagnostic system created to:
- take photos of the anterior segment of the eye
- measure the refractive power of the eye
- measure the central corneal K-values.

- is based on the Scheimpflug Principle for Slit Image photography. The measuring system uses blue light (UV-free) given to a slit to illuminate the eye, and a CCD-Camera for photography. The device takes a series of images of the anterior segment of the eye from one fixed location (180°) and analyses one, selected by software
- has a real keratometer to measure directly the central keratometer values as per definition in the 3.1mm ring.
- includes an Ophthalmic Refractometer to measure the refractive power of the eye (21CFR886.1760)
The device consists of a measurement unit, built in CPU, head and chin rest and an external power supply.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
In an internally performed study 46 subjects (92 eyes) were examined with an OCULUS PARK 1 by the same operator to determine the repeatability of the measurement results of the Pachymetry and Keratometry. Both eyes of a patient were measured and every eye was measured three times with the same device. The measurement ranges of the examined eyes were: Apical Thickness [460 .. 636um]; Min. Thickness [453 .. 635μm] ; K1 [38.66 .. 46.04dpt] ; K2 [39.02 .. 47.14dpt]. For this study design repeatability is a pooled standard deviation across subjects and eyes calculated in the following manner: For each set of triplicate results per eye per subject, the variance (standard deviation squared) had been calculated. Then these variances were averaged and the square root of the average had been taken.

Brief summary of nonclinical tests and results
In an internally performed study 46 subjects (92 eyes) were examined with an OCULUS PARK 1 by the same operator to determine the repeatability of the measurement results of the Pachymetry and Keratometry. Both eyes of a patient were measured and every eye was measured three times with the same device. The measurement ranges of the examined eyes were: Apical Thickness [460 .. 636um]; Min. Thickness [453 .. 635μm] ; K1 [38.66 .. 46.04dpt] ; K2 [39.02 .. 47.14dpt]. For this study design repeatability is a pooled standard deviation across subjects and eyes calculated in the following manner: For each set of triplicate results per eye per subject, the variance (standard deviation squared) had been calculated. Then these variances were averaged and the square root of the average had been taken.
