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.

Pathological changes can be quantified and possible effects on visual acuity can be explained.
Comparing Examinations
With the Compare 4 Exams display you can now compare up to four examinations. Changes from the first to the latest measurement can easily be displayed, reflecting the course of disease over time. Select the examination that you wish to compare (A, B, C, D) with only two clicks and see the results right away – independently of the curvature type. The easy-to-understand display helps you describe even complex matters to your patient.

Pathological changes can be exactly localized, and changes in size can be determined. This ensures that all of your patients questions will be answered.
Make a quick and easy decision whether your patient has dry eye symptoms.
Get equipped to give your patients specific advice for easing their dry eye symptoms.
Regular check-ups will make you the go-to specialist for your patients.
The Tear Map shows the affected areas: The respective break-up time is graphically illustrated for each Segment in seconds and according to the principle of a traffic light.
Evaluation of Lipid Layer
Hyper-evaporative dry eye is easily overlooked when using conventional tests. Thus evaluating the lipid layer of the tear film is even more important. With the Keratograph 5M you can record videos of interference patterns of the lipid layer. Distribution characteristics, morphology and thickness of the lipid film can be continuously evaluated.
Tear Film Dynamics
The tear film contains numerous particles. These can be made visible using a specific light source. These particles are distributed in the tear fluid from Bottom to top during each blink. The velocity of these particles provides information on tear film viscosity. You can quickly and easily evaluate the quantity and movement of these tear film particles using the TF-Scan.
JENVIS Grading Scales
These four-point grading scales allow easy classification of MGD based on an individual meibography. Reference-state images assist in classifying the gland structure as normal or indicative of mild or severe MGD.
Bulbar and Limbal Redness
Different display options help to classify the degree of redness. Choose between camera image, view of fine vessels in the conjunctiva, red-free or contrast-enhanced display. Bulbar and limbal redness are evaluated in the temporal and nasal areas and all results are saved automatically.
Easy-to-Understand Patient Education
The oxygen transmissibility (Dk/t) depends on the material the contact lens is made of and on its thickness. In the past, only the manufacturers’ specifications about the oxygen transmissibility in the center of a -3,00 D contact lens were available. With the OxiMap®, you now get a graphic visualization of the Dk/t values over the whole area, based on the lens thickness.
The Dk/t values are colour-coded, whereby black represents an oxygen supply lower than that present in a closed eye. To preserve the integrity of the cornea when wearing contact lenses, minimum Dk/t values are recommended based on the length of time the contact lenses are to be worn. The OxiMap® colour-coding is based on these international recommendations.
Compare Different Soft Contact Lenses!
The OxiMap® is individually adapted based on the lens power and supports you in your consultation with the patient and helps you to choose the most suitable contact lens. New materials used for soft contact lenses provide excellent oxygen transmissibility.
OxiMap® was developed in close cooperation with JENVIS Research and the University of Applied Sciences in Jena.

Measurements With Placido Ring Illumination
White ring illumination is used to measure thousands of points on the corneal surface. Infrared ring illumination is also available for analyzing the tear film in order to prevent reflex tear secretion caused by glare.
