LipiView | Dry Eye Testing | Premium Vision SC


Most advanced diagnostic test for dry eyes/MGD


The LipiView Ocular Surface Interferometer: The LipiView Interferometer measures the absolute thickness of the tear film lipid layer by analyzing more than one billion data points of the interferometric image of the tear film. The patient’s tear film can be seen as an array of colors. Physicians and patients will now be able to see the interference pattern from the tear film and have a visual reference to view specular observations of the tear film. In addition to viewing, capturing, manipulating and storing digital images of specular observations of the tear film, a patient’s blinking pattern can be evaluated.


The LipiView Interferometer operates on the principle of broad-spectrum white light interferometry, and provides a interferometric color assessment of the tear film by specular reflection. The patient’s eye is positioned in front of an illumination source that’s directed toward the tear film on the corneal surface. Light from this source passes through the tear film and is specularly reflected into a camera. The light reflecting back through the lens in the camera forms an interference pattern, called an interferogram. The advanced computer system then captures and records 32 frames per second, in real time.
