No
The document mentions "computer-assisted cell counting and cell analysis capabilities" and "image processing" but does not explicitly state or imply the use of AI or ML algorithms for these functions. The description of the technology is consistent with traditional image processing techniques.
No
The device is used for examination and measurement (diagnostic purposes) and does not deliver any therapy.
Yes
The device is described as a specular microscope and optical pachymeter intended for examination of the corneal endothelium and measurement of corneal thickness. It includes "cell counting and analysis programs" and is indicated "when it is desired to analyze the images of the cell distribution of the eye," all of which are diagnostic functions.
No
The device description clearly states it is a "specular microscope and optical pachymeter," which are hardware components. It also mentions a camera, infrared techniques for focusing, and storing images on magnetic tape or a video printer, all indicating a physical device with integrated hardware. While it includes software for analysis and control, it is not solely software.
Based on the provided information, the Konan Noncon Robo Pachy is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states that the device is for the "examination of the corneal endothelium" and "measuring the corneal thickness." These are direct measurements and observations of a living tissue within the body (in vivo), not tests performed on samples taken from the body (in vitro).
- Device Description: The description reinforces that it's a "non-contact ophthalmic microscope, optical pachymeter, and camera intended for examination of the corneal endothelium and for measurement of the thickness of the cornea." This further emphasizes its in vivo application.
- Lack of In Vitro Activities: There is no mention of analyzing biological samples (blood, urine, tissue biopsies, etc.) or performing tests on substances outside of the body.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. The Konan Noncon Robo Pachy operates directly on the patient's eye.

Device Description
The Noncon Robo Pachy specular microscope and optical pachymeter is a non-contact ophthalmic microscope, optical pachymeter, and camera intended for examination of the corneal endothelium and for measurement of the thickness of the cornea. It is an improvement to the original Konan Noncon Robo, K950091.
The device permits visual inspection and photography of corneal endothelium and measurement of the corneal the thickness without any object contacting the eye. It features focusing by means of infrared techniques, and computer-assisted cell counting and cell analysis capabilities. The computer functions are also used to aid in setting up the various features of the machine and to aid in photography. Photographic images are temporarily stored in the system's memory, and are preserved in video form on magnetic tape or by using a video printer. The memory can store two endothelial cell images and two anterior segment images, which are usually those of the left and right eyes.

Summary of Performance Studies
Non-clinical tests done for the original Noncon Robo also apply to the Noncon Robo Pachy. A new software validation test has been performed to validate the new software. The system meets the requirements of the standards JIS T 1001-1988 (Safety Code for Medical Devices), JIS T 1002 (General Rules of Testing Methods for Safety of Medical Electrical Equipment), and the standards of the EMC Directive 89/336/EEC. The accuracy of the pachymetry system has been established by tests on an accurately machined phantom.
Corneal thickness measurements made on 100 patients have been compared with measurements on the same patients using the DGH 2000 ultrasonic pachymeter. This test shows that the Noncon Robo Pachy gives at least an accuracy equivalent to the DGH 2000.

Dear Dr. Myers:
This letter updates our substantially equivalent letter of April 24, 1998 regarding the product code and classification regulation of your device. Specular microscopes are now regulated under §886.1850 (AC-powered slitlamp biomicroscope) and are listed under a new product code (NQE). This letter is for informational purposes. No further action is required on your part at this time.
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 indictions 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 (PMA). 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 mistranding and adviteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

(6) Technological characteristics
The Konan Noncon Robo Pachy is technically the same as the predicate device, the Konan Noncon Robo, with the addition of more accurate sensors to provide sufficient accuracy for clinical pachymetry measurements. The original Noncon Robo, sold as a specular microscope, had the ability to measure corneal thickness, but the measurements were not accurate enough for clinical use. The "Pachy" version has more accurate sensors. The computer program that controls the system has been modified to permit display and control of the pachymeter feature. -
(b) Performance data
- (1) Non-clinical tests
The non-clinical tests done for the original Noncon Robo also apply to the Noncon Robo Pachy, since the device is essentially the same. A new software validation test has been done, to validate the new software. The system meets the requirements of the standards JIS T 1001-1988, Safety Code for Medical Devices, and JIS T 1002, General Rules of Testing Methods for Safety of Medical Electrical Equipment, and the standards of the EMC Directive 89/336/EEC.

has the certificates and details on the tests. The bench test section has a Declaration of Conformity to the EEC tests. The accuracy of the pachymetry system has been established by tests on an accurately machined phantom, and are in the Bench Test Section.
(2) Clinical tests
Corneal thickness measurements made on 100 patients have been compared with measurements on the same patients using the DGH 2000 ultrasonic pachymeter. This test shows that the Noncon Robo Pachy gives at least an accuracy equivalent to the DGH 2000.
(3) Conclusions
The Konan Noncon Robo Pachy is equivalent in safety and efficacy to the legally marketed predicate devices.
