    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.



    Easy-to-Understand Presentation

    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.

    NEW JENVIS Dry Eye Report

    Find the cause of dry eye quickly and reliably. The JENVIS Dry Eye Report is an unique tool for doing this. After measurements are taken using the Keratograph® 5M and the slit lamp, your customer/patient receives an easy-to-grasp print-out. The Dry Eye Report combines screening and consultancy.

    Tools for the JENVIS Dry Eye Report – Here's How it Works

    Drawing up a comprehensive Dry Eye Report entails filling out a questionnaire, measuring the LIPCOF using the slit lamp and taking four measurements
    using the Keratograph® 5M. Other nationally and internationally approved screening methods can be added with ease – numerous supplementary
    procedures ranging from eyelid blink frequency to staining are incorporated into the Keratograph® 5M.

    Dry Eye Questionnaire (DEQ)

    What good would a screening be without history taking ? Commonly used questionnaires are incorporated into the Dry Eye Report on the Keratograph® 5M.
    • OSDI (Ocular Surface Disease Index) ?
    • McM (McMonnies)
    You can choose your favourite one.

    A look through the slit lamp

    The slit lamp is the number one instrument when it comes to eye diagnostics. To draw up a comprehensive Dry Eye Report it is necessary
    to assess the LIPCOF (lid-parallel conjunctival folds). You enter the results into the Dry Eye Report on the Keratograph® 5M.

    Non-invasive measurements

    The practical tools provided by the Keratograph 5M help you perform comprehensive Dry Eye analysis. Analyzing the level of redness using R-Scan, measurement of tear meniscus height, tear film break-up time and meibography can all be performed with ease using the Keratograph® 5M.
    The result ? A comprehensive Dry Eye Report.


    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.

    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.


    Meibography of the Top and Bottom Eyelid

    The multi-functionality of the new Keratograph® 5M enables even difficult examinations, such as Meibography, to be integrated with ease and efficiency into routine ophthalmological and optometric check-ups. A dysfunction of the Meibom glands is the most common cause of Dry Eye. The associated morphological changes in the glandular tissue can be made visible with the Meibo-Scan.


    Indispensable for:

    • Fitting multi-focal contact lenses
    • Exact determination of the treatment area for refractive surgery
    • Seamless integration into the existing Keratograph® software
    • The infrared camera installed in the Keratograph delivers images of the patient’s pupil, which are used as the basis for the measurements

    Different Ways of Determining Pupil Reaction:

    • Examination of the pupil reaction both with and without glare
    • Examination using two different glare stimulus powers
    • Clear presentation of the results in graphic form: pupil changes over a period of time; minimum, maximum and mean pupil diameter, incl. standard deviation
    • Comparison views possible

    Optional Imaging Software*

    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.

    How Does That Work?

    • Simply integrate the Imaging Software into the Keratograph® software
    • Blue light-emitting diodes in the illumination beam path stimulate the fluorescein
    • Yellow filters are integrated into the observation beam path

    Result: Static fluorescein-images and videos can be recorded under slit lamp conditions!

    Indispensable for:

    • Demonstrating the fit of contact lenses
    • Assessment of the static fluo-image
    • Assessment of the fit of contact lenses at different pupil sizes
    • Comparison of fluo-image simulations with real-time fluo-images
    • Selection of the best possible contact lens
    • Consultation and customer retention


    OCULUS OxiMap®

    The OxiMap® presents a color map of the oxygen transmissibility of soft contact lenses based on the lens power, which is easy to understand – even for your customers!

    Oxygen Transmissibility of Soft Contact Lenses Made Visible

    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 color map of the oxygen transmissibility of soft contact lenses based on the lens power – which even your customers will understand!

    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.
