OCULUS Keratograph 5M |
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!
The new joystick for the Keratograph 5M allows you to capture images and video sequences directly from the device. No need to use the mouse: your hand just stays on the joystick when you capture images or videos.
The new joystick communicates via a smart Bluetooth interface. And it does away with the need for cumbersome power cabling. The joystick switches to sleep mode function when not in use to extend battery life.
Switching to the new joystick is quick and simple. Watch the video below to see how easy it is!
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.
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.

Find the cause of dry eye syndrome quickly and reliably. The new JENVIS Pro Dry Eye Report in the Keratograph 5M will help you as you go along. Perform a comprehensive screening, using the measuring results as a basis for diagnosing dry eye syndrome. All results are documented in accordance with the Medical Products Law and summarized for your patient in a neat and easily understandable printout.
Make use of all the advantages of the new JENVIS Pro Dry Eye Report in the Keratograph 5M: efficient screening, well-founded measurement results and greater patient loyalty.
Screening for dry eye syndrome should be a routine part of every refraction.
The four-part screening test quickly and accurately reveals abnormalities in tear film quantity and quality. This 5-minute screening should be carried out routinely before every refraction. The JENVIS Pro tear film screening routine includes measurement of the tear meniscus height, tear film break-up time, bulbar redness and a short questionnaire.
Make a quick and easy decision whether your patient has dry eye symptoms.
The JENVIS Pro Dry Eye Report provides you with a fail-safe test sequence covering all the assessment criteria required for a comprehensive analysis for dry eye syndrome. It provides you with useful hints and optimized, predefined settings to support you in your measurements, enabling you to perform a quick and efficient analysis for dry eye syndrome and document your anterior segment findings.
Get equipped to give your patients specific advice for easing their dry eye symptoms.
You want to know whether your treatment recommendations have been successful? Then use the follow-up function with its setting options for characterizing the initial cause. This will enable you successfully document improvements in your patients‘ tear film condition.
Regular check-ups will make you the go-to specialist for your patients.
The tear film is assessed using either white or infrared illumination. The new high-resolution colour 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.
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.
The height of the tear 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.
The interference colours 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 colour.
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.
Automatic classification of the bulbar redness. Conjunctival redness used to be assessed subjectively and depended on the examiner. The R-Scan is the first module that automatically and objectively documents and classifies the bulbar and limbal degree of redness. The R-Scan detects the blood vessels in the conjunctiva and evaluates the degree of redness. This automatic assessment spares you the time and effort of having to make manual comparisons using classification sheets.
The multi-functionality of the Keratograph 5M easily and efficiently integrates difficult examinations such as meibography. The dysfunction of meibomian glands is the most frequent cause of dry eye. Morphological changes in the gland tissue are made visible using the Meibo-Scan and can be classified with the JENVIS Meibo Grading Scales.
The Imaging Software is used to record video and image files. In addition to viewing the videos and single images by themselves, you can also compare the recordings with the simulated fluorescein-images of the measured eye.
Result: Static fluorescein-images and videos can be recorded under slit lamp conditions!
The OxiMap® presents a colour map of the oxygen transmissibility of soft contact lenses based on the lens power, which is easy to understand – even for your customers!
An intact tear film and a good supply of oxygen to the cornea are an absolute necessity for wearing contact lenses comfortably. The OxiMap® presents a colour map of the oxygen transmissibility of soft contact lenses based on the lens power – which even your customers will understand!
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.
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.

In a perfect world, patients would present with a single, obvious cause for their dry eye and management would be simple, quick and effective. Yet there are often multiple factors that contribute to the presence of dry eye and they need to be identified as contributors for best management. A tool such as the OCULUS Keratograph 5M with specific JENVIS Pro Dry Eye Report software allows for advanced testing to understand the subtleties and complex nature of the ocular surface and tear-film.

More often than not, patients do not present with a text book case of a single issue. Usually, they have a combination of concerns that may or may not be relevant to each other. In the world of contact lenses, comfort and drop out are often related to a poor ocular surface, rather than the latest generation of contact lens products. This case report demonstrates how multi-tasking tools, such as the OCULUS Keratograph 5M, allow us to investigate multiple issues and concerns in a parallel stream allowing maximum efficiency and outcome.
