The innovation
in corneal analysis

Corneal Biomechanics background image
Thanks to the corneal biomechanics, it is possible to measure what was previously not measurable. This raises keratoconus diagnosis and glaucoma screening to a new level. Crucial for this: the perfect combination of biomechanical analysis, tonometry and pachymetry. learn more

What do I need biomechanics for?

Do you really know what biomechanical properties are?
And what it has to do with the cornea?

Watch our video to find out in only 3 minutes!

How does it work in my daily practice?

By combining tomographic data from the Pentacam® examination with biomechanical data from the Corvis® ST, you are able to further improve sensitivity and specificity in the detection of patients with a significant risk for developing ectasia after refractive surgery.

Take care of more patients with greater safety!
