Got Dry Eyes?

The OCULUS Keratograph® 5M

can help with accurate diagnosis!

The Keratograph® 5M examination

There is an advanced technology called the OCULUS Keratograph® 5M. It helps Ophthalmologist and Optometrists in accurately diagnosing the Dry Eye Syndrome and documenting the findings. If treatment is necessary, the Keratograph® 5M can compare the before and after treatment results to evaluate the success of the treatment.

Quality and quantity of the tear film

To measure the quality and stability of the tear film, the OCULUS Keratograph® 5M measures the tear film break up time non-invasively. This test takes less than 30 seconds and does not require touching the eye. To evaluate the quantity of the tear film, the Keratograph® 5M takes a picture of the lower eyelid to measure the tear meniscus height.

Lipid Layer

The Keratograph® 5M can document a movie of the oily layer of the tear film. A healthy and thick lipid layer is colorful and protects the tears from fast evaporation. If there is not enough lipid, the tear film becomes unstable, the moisture dissipates quickly and both vision and comfort can be compromised.


Located in both upper and lower lids, the meibomian glands produce complex oils that stabilize the tear film and prevent tear evaporation. If the meibomian glands do not function properly dry eye usually occurs. Your doctor can utilize the advanced features of the Keratograph® 5M to directly assess the health of your meibomian glands.
