The OCULUS Keratograph 5M combines corneal topography and dry eye analysis in one machine. The machine uses Placido disc illumination to take measurements of the ocular surface, and different colors of light emitting diodes (LEDs) are used depending on the application. The Keratograph 5M offers Meibo-Scan for meibography of the upper and lower eyelid to check for Meibomian Gland Dysfunction (MGD), TF-Scan for evaluation of the tear film break-up time, and R-Scan for automatic bulbar redness classification.
The Keratograph 5M features a high-definition color camera that can take both images and video. And the device’s built-in software lets me view 2D and 3D images as needed.
