No
The summary describes standard image processing techniques and does not mention AI or ML.
No
The device is described as an "ophthalmic imaging device" used to capture, archive, manipulate, and store digital images of the tear film. Its purpose is diagnosis and monitoring, not direct treatment.
Yes
The device is intended for use by a physician to capture, archive, manipulate, and store digital images of specular observations of the tear film, which can be visually monitored and photographically documented. This process helps in assessing the tear film, which is a diagnostic activity.
No
The device description explicitly states it is a "bench-top imaging device containing a computer system and electronics, chin rest and forehead rest, camera and zoom lens, illuminator and a touch screen display," indicating it includes significant hardware components beyond just software.
Based on the provided information, the LipiView® Ocular Surface Interferometer is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states that the device is used to "capture, archive, manipulate and store digital images of specular (interferometric) observations of the tear film, which can be visually monitored and photographically documented." This describes an imaging device used for visual assessment and documentation of a physical structure (the tear film) on the surface of the eye.
- Device Description: The description details a bench-top imaging device that uses white light interferometry to assess the tear film. It captures video images of the ocular surface.
- Anatomical Site: The device operates on the "Ocular surface and tear film."
- Lack of In Vitro Testing: There is no mention of the device being used to test samples of human origin (like blood, urine, tissue, etc.) outside of the body. IVD devices are specifically designed for such testing.
The LipiView® is an ophthalmic imaging device used for in-vivo observation and documentation of the tear film on the eye's surface. This falls under the category of medical devices used for diagnosis or monitoring based on imaging and visual assessment, not in-vitro testing of biological samples.

Device Description
The LipiView® Ocular Surface Interferometer is a bench-top imaging device containing a computer system and electronics, chin rest and forehead rest, camera and zoom lens, illuminator and a touch screen display. The LipiView® Interferometer operates on the principle of white light interferometry and provides an interferometry color assessment of the tear film by specular reflection. The computer system captures a video image file that is recorded over time since the interference pattern changes as the tear film is distributed across the cornea during blinking. The video image of the ocular surface may be viewed on the computer screen display and in a printed report.

DEVICE DESCRIPTION:
The LipiView® Ocular Surface Interferometer is a bench-top imaging device containing a computer system and electronics, chin rest and forehead rest, camera and zoom lens, illuminator and a touch screen display. The LipiView® Interferometer operates on the principle of white light interferometry and provides an interferometry color assessment of the tear film by specular reflection. The computer system captures a video image file that is recorded over time since the interference pattern changes as the tear film is distributed across the cornea during blinking. The video image of the ocular surface may be viewed on the computer screen display and in a printed report.
INTENDED USE
The LipiView® Ocular Surface Interferometer is an ophthalmic imaging device that is intended for use by a physician in adult patients to capture, archive, manipulate and store digital images of specular (interferometric) observations of the tear film, which can be visually monitored and photographically documented.

SUBSTANTIAL EQUIVALENCE TO THE PREDICATE DEVICES
The intended use and technologic characteristics of the LiviView Interferometer are substantially equivalent to the OphthaVision Imaging System (K980295) and Tearscope-Plus (K973064). All three devices are prescription devices for imaging use by a physician during an in-office exam.
The LipiView Interferometer and the OphthaVision Imaging System are intended to capture, archive, and manipulate digital images of the imaging focal plane with the LipiView Interferometer is at the ocular surfacc and tear film, whereas the OphthaVision Imaging System can be used for intraocular imaging. Both devices provide a means to store digital images to allow a physician to monitor and photographically document conditions.
The LipiView® Ocular Surface Interferometer has similar technological characteristics to the OphthaVision Imaging System. Both devices use a digital camera. Microsoft Windows-based software, computer, monitor, graphical user interface, user controls, printer support, image storage drives, and AC power source. Both devices allow the user to select functions to process, analyze, archive and retrieve images. Analogous software features include image enhancement, alignment, comparison, animation, capture/save and print. The two devices store data in a similar Lossless file format,
Furthermore, the LipiView Interferometer and the Tearscope-Plus have the same intended use to observe the tear film by specular reflection. Both devices allow the physician to observe tear film. The LipiView® Interferometer has similar technological characteristics to the Tearscope-Plus. Both devices use a diffuser and low-level white light to illuminate the eye on an angle and view real-time tear film dynamics. Both devices show the interference patterns for evaluation of the colors observed in the tear film. The LipiView Interferometer and Tearscope-Plus are required to meet optical radiation safety standards.
The LipiView® Interferometer, OphthaVision Imaging System and Tearscope-Plus are all AC-powered devices that are required to meet electrical safety and electromagnetic compatibility standards. All three devices do not contact the patient's eye.
The LipiView Interferometer includes a chin rest support system to position the patient's head during imaging, whereas the OphthaVision Imaging System and the f earscope-Plus are used with a slit lamp biomicroscope that provides a chin rest support to position the patient's head. The chin rest support materials for the LipiView Interferometer are widely used in ophthalmic slit lamp biomicroscopy products and are known for biocompatibility. Therefore, this difference does not raise new questions of safety and effectiveness. In addition, the LipiView® Ocular Surface Interferometer conforms to disinfection of patient contact surfaces for slit lamp biomicroscopes.
Minor differences in technology between the predicate devices and the LipiView Interferometer do not raise new questions of safety and effectiveness and are supported by performance testing to applicable standards and software verification and validation. Table 5-1 compares the LipiView® Interferometer to the predicate devices.

PERFORMANCE TESTING:
The LipiView® Ocular Surface Interferometer conforms to the requirements under the applicable standards for slit lamp biomicroscopes; optical radiation safety; electrical safety; and material flammability. In addition, the LipiView® Interferometer is designed and will be manufactured in compliance with voluntary consensus standards for risk management and quality management systems. The LipiVicw Interferometer software was developed and tested in compliance with FDA Guidance documents for software validation in medical devices.
CONCLUSIONS:
The LipiView® Ocular Surface Interferometer has comparable intended use and technologic characteristics to the predicate devices. Minor technological differences between the LipiView® Interferometer and the predicate devices do not raise new questions of safety and effectiveness and are supported by performance testing, TearScience has demonstrated through its evaluation of the LipiView Ocular Surface Interferometer that the device is substantially equivalent to the predicate devices.
