The 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.
With the Keratograph® 5M, you can show your patients images they have never seen before. Gain patient trust by providing professional consultation during examinations and follow-ups.
Actively integrate the Keratograph® into your consultation. Many easy to understand displays support you in communication and patient education. Use your Keratograph®5M as a marketing tool to make your services transparent!
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® 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.
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.
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.
