Measurements with Placido Ring Illumination

Thousands of measuring points are used to measure the whole surface of the cornea. A white ring illumination is used for this purpose. An infrared ring illumination is also provided for analysis of the tear film to prevent glare-related reflex secretion.

Measurements with Light Emitting Diodes

The perfect illumination has been integrated for every function of the Keratograph® 5M: White diodes for the tear film dynamics, blue diodes for fluo-images, infrared diodes for Meibography.

TF-Scan

The tear film is assessed using either white or infrared illumination. The new high-resolution color camera makes even the finest of structures visible. In addition to NIKBUT (Non-Invasive Keratograph® Break-Up Time) and measurement of the meniscus tear, the TF-Scan can also make an assessment of the lipid layer and the tear film dynamics. Tear film analysis with the OCULUS Keratograph® 5M is non-invasive and is conducted without any additional tools.

Assessment of the Tear Film Break-Up Time

The tear film break-up time is measured non-invasively and fully automatically. The new infrared illumination is not visible to the human eye. This prevents glare during the examination. The TF-scan presents the results in a way that is easy for you and your customers to understand.

Lipid Layer
Assessment of the Interference Phenomenon

The interference colors of the lipid layer and their structure are made visible and can be recorded. The thickness of the lipid layer is assessed based on the structure and color.

TF Dynamics
Assessment of the Particle Flow

The video recording, with up to 32 frames per second, enables the observation of the tear film particle flow, from which conclusions regarding the viscosity of the tear film can be drawn.
