Oculus 5km Dry Eyes

dry eyes

With the advent of the K5m we can now examine your eyes and tears in a way not previously possible. Below are some of the advanced features of the K5m that make up just part of a dry assessment at Maddox Dry Eye Centre.

Lipid Layer Thickness

The depth and spread of meibum (oil) is analysed, a healthy layer giving a colourful oil-slick appearance. If too thin or absent the tears will evaporate too quickly.


The meibomian glands sit just below the skin of the eyelids and it is possible to create an image of them using infra-red light. Analysing their structure provides vital information in the assessment of your dry eye condition.

Tear Film Dynamics

A recording of up to 32 images per second enables observation of the ‘tear particle flow characteristics’. The results are used to evaluate the viscosity, or thickness of the tears.


This is first and only technology that automatically and objectively measures and classifies the degree of ocular redness. The K5m is able to distinguish the thinner conjunctival vessels affected by dry eye.

Tear Break-Up Time

Any break-up of the tears will result in dry eye symptoms. The K5m is able to accurately document the exact corneal position of any tear break-up and the time taken.
