OCULUS Keratograph 5M Topographer


Keratograph 5M Topographer is a sophisticated corneal topographer using a built-in real keratometer plus a color camera optimized for external imaging. Unique features include analyzing the meibomian glands, noninvasive tear picture break-up time and the tear meniscus height measurement and assessing the lipid layer.

The OCULUS Keratograph 5M combines corneal topography and ironic eye evaluation in one machine. The machine uses Placido disc illumination to take measurements of the ocular surface, and different colors of light emitting diodes (LEDs) are used depending on the application.

The Keratograph 5M features a high profile color camera that can take both images and video. And the apparatus’s built-in software lets me view 2D and 3D pictures as needed.

The Oculus Keratograph 5M is a new patient-friendly and multi-purpose device that efficiently integrates complex evaluation, into a sterile eye evaluation and report. It performs such tests as meibography, eye redness analysis, and Tear Break-Up Time (TBUT). Meibography is an advanced technique using infrared technology to image the anatomy of the oil glands, found in the upper and lower eyelids. These glands are unique because they provide the natural lubrication to keep the tears wholesome. It takes place when the oil glands have been compromised (i.e., congested, tortuous, dilated, or atrophied). When assessing MGD, we assess both anatomy of the glands as well as the function.

One benefit of the Keratograph 5M is it is a user-friendly apparatus. The corneal topography portion of the evaluation is non-contact, and the vast majority of the tender eye evaluations are as well — you can use a cotton swab on the eyelid through the meibomian gland topography.

Another big advantage is that it will help fill the void between diagnosing and educating patients about their ocular surface. The system provides me with a simple-to-understand color map and reports that patients can look at and take home together. This allows me to enroll patients in their care and supply them with a specific treatment plan for their particular ocular needs.

Featuring easy-to-understand displays, this revolutionary tool helps make our services transparent, so you feel in control of your eye health and treatment path. The OCULUS Keratograph 5M features:

  • Thousands of points used to measure all areas of the cornea, via white ring illumination (Placido Ring Illumination) that also allows for analysis of the tear film to keep glare-related reflex secretion at bay.
  • Several illuminations for each function of the Keratograph® 5M, i.e., white diodes for tear-film dynamics, blue diodes for fluo-images, infrared diodes for Meibography.
  • This advanced technology can help diagnose dry eye syndrome, with the ability to compare the before and after treatment results to evaluate success.
  • A non-invasive test that takes just a half hour to complete, with no touching of the eye!

Dry eye can be very problematic for patients. In healthy eyes, a fresh layer of tears, called tear film, spreads over the eye when you blink. When this tear film fails to keep the eye moist and comfortable due to the failure to produce enough tears, dry eye syndrome can result.

Keratograph 5M Software


Find the cause of dry eye quickly and reliably. The JENVIS Dry Eye Report is a 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.


Patient consultation made easy. This software shows the quality and quantity of the tear film.

In cases of dry eye patients and contact lens wearers, the tear film should be examined carefully. Only an intact tear film guarantees contact lens wearing comfort! The Keratograph® 4 measures the tear film breakup time non-invasively (quality assessment). You can show your patient the individual tear film quality using the color maps. In addition, you can take another non-invasive measurement to determine the amount of tear film (tear film quantity).


The OCULUS Keratograph® 4 determines the break-up time using the NIKBUT procedure (non-invasive-Keratograph-break-utime).


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.


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.


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.


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 multifocal contact lenses
  • Exact determination of the treatment area for refractive surgery
  • Seamless integration with 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


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.


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!


includes PC, table, device, installation, training, 1-year warranty, lifetime updates, and online and phone support.
