OCULUS Corvis® ST OCULUS Pentacam® AXL

I just took a look at the tomography. These values call for caution.
I don’t think I would operate.

The biomechanics looks good, though.
The cornea is very stable.
I don’t see any problem with operating.

What do I need

biomechanics for?

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

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!

Integration of Scheimpflug-Based Corneal Tomography and Biomechanical Assessments, Renato Ambrósio Jr, MD, PhD

Prof Ambrósio Jr talks about ...

... how he uses the Corvis® ST in his daily practice

  • What are the novel feautures of the new OCULUS Corvis® ST?
  • What is the role of Corvis biomechanical metrics for ectasia detection?
  • What does the Corvis® ST measure?

... the advantages of integrating tomography and biomechanics

  • Can you give a brief update how to detect ectasia based on
    corneal biomechanics?
  • What is the advantage of integrating tomography and biomechanics?
  • What will be the future of screening for ectasia risk prior to
    refractive surgery?


Integration of Scheimpflug-Based Tomography and Biomechanical

Assessments for Enhancing Ectasia Detection

R. Ambrósio et al. (July 2017)

Integration of Scheimpflug-Based Tomography and Biomechanical Assessments for Enhancing Ectasia Detection

This publication is about the clinical validation of the Tomographic Biomechanical Index (TBI). On a database of more than 800 eyes, it is proven that the TBI provides higher accuracy in detecting ectasia than all other methods including corneal topography, corneal tomography and biomechanical analysis.
