Topography Made Easy With Oculus Keratograph 5M

The OCULUS Keratograph 5M is an advanced corneal topographer with a built-in real keratometer and a color camera optimized for external imaging. Unique features include examining the meibomian glands, non-invasive tear film break-up time and the tear meniscus height measurement and evaluating the lipid layer. The high-resolution color camera and the integrated magnification changer offer a new perspective to the tear film assessment procedure. 

In addition to these unique features, the Keratograph 5M precisely measures corneal topography. The built-in real Keratometer and the automatic measurement activation guarantee perfect reproducibility of the Ks. The data from the non-contact measurement is automatically analyzed and shown in comprehensive presentation formats.

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.

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 5 M 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.




Meniscus Tear Height Assessment of the Tear Film Quantity

The height of the torn meniscus can be precisely measured with an integrated ruler and various magnification

options, and its development along the edge of the bottom lid can be assessed. The results are saved to the patient file.




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.
