The feature-rich Oculus Keratograph 5M is also a good tool for patient education.


“Using the OCULUS Keratograph 5M for meibography is great for patient education as well as directing treatment. Seeing the glands on-screen is a powerful motivator to improve compliance in the management of meibomian gland dysfunction (MGD).”

“The K5 has been a valuable tool for my research. It has provided me with an efficient means of analyzing meibomian gland changes.”

Looking for a state-of-the-art topographer? The Keratograph 5M offers versatility plus more.

When my wife and I decided to build a high-tech practice from scratch, we wanted to incorporate the latest technology””keeping in mind both space and financial constraints. Selecting the right technology wasn’t easy. Ideally, we wanted state-of-the-art instruments that met both of our needs””management and retinal imaging””but also provided detailed anterior segment images.

At the top of my list of favorite devices is the OCULUS Keratograph 5M. With complex contact lenses and ocular surface disease a growing part of our practice, we wanted a top-notch topographer that was feature-rich.

I especially like the Keratograph 5M’s ability to easily model the cornea in 3D. It’s an amazing tool for patient education and really showcases our high-tech approach to care. Corneal mapping is also essential for pre-operative workups for cataract and refractive patients, troubleshooting post-op problems, and in ruling out corneal irregularity as a cause of decreased vision.

It was my interest in the ocular surface and tear film, however, that really got me excited about the Keratograph 5M. TF-Scan software, a high-resolution color camera, and both white and IR LEDs give the Keratograph 5M capabilities for ocular surface imaging that are truly game changing.

Tear film breakup time has always been one of the best indicators of tear stability. However, everything from the amount of fluorescein instilled to an examiner’s ability to count time reduces accuracy and reproducibility of this critical measure.

The Keratograph 5M includes the TF-Scan software suite which incorporates automated non-invasive keratograph breakup time (NIKBUT) measurement. The results are displayed both with a color-coded graphic of the ocular surface and a tear breakup/time graph offering precise metrics. Infrared illumination is used to minimize the effects of glare.

Also included are modules for precise measurement of tear meniscus height, assessment of tear dynamics using particle flow, and a module that displays lipid layer thickness and integrity using interference patterns.

With the intense focus on meibomian gland dysfunction as a primary cause or a contributor to dry eye, the Keratograph’s 5M Meibo-Scan imaging allows direct assessment of meibomian gland structure. Congestion, blockage, and gland atrophy and dropout are easily visualized using IR illumination.

The Keratograph 5M is a key part of our dry eye workup and essential for many of our contact lens fits. The benefit of incorporating so many useful functions into a single instrument has increased efficiency and maximized office space. It’s one of the instruments that helps define our practice as cutting-edge.
