Ectasia Screening
Screening the eyes for ectasia improves early detection coverage as well as safety in surgical planning.
TBI – Double Down On Your Decision
The Tomographic Biomechanical Index (TBI) assesses the risk of corneal ectasia at a glance. The value is calculated automatically from the measurement data of the Pentacam® and the Corvis® ST — in real time during the analysis.
This allows you to act and decide with certainty, precisely when it matters.
What makes the TBI unique?
A single value (0–1) indicates the risk in a clear and simple way
Two measurement methods provide the basis
Pentacam®: analysis of the corneal shape
Corvis® ST: measurement of biomechanical stability
The assessment is automatic — with a simple traffic light system: Green. Yellow. Red. And with greatest precision.
This allows you to recognize critical changes before they become clinically visible.

Why ectasia screening is so important
Diagnosing corneal ectasia at an early stage is of paramount importance, as it increases the chances of treatment success and preserving patients‘ vision over the long term. If detected at an early stage, the disease can often be fended off simply with a pair of spectacles or contact lenses. By contrast, advanced ectasia can sometimes only be countered with a corneal transplant.
How to detect ectasia reliably
Whether performed as part of an eye health check-up or on the occasion of a planned surgery, in order to be effective, ectasia screening should always include both the tomography and the biomechanics of the cornea. A screening procedure that combines both is essential for this.
Early detection of corneal ectasia (keratoconus)
Ectasia screening allows early detection of structural changes of the cornea, in particular keratoconus and astigmatism. It can also reveal deviations in corneal thickness, an important indicator of incipient ectasia. This can be vital in enabling treatment to start at an early stage and preventing vision impairment.
Dual-method screening improves safety
As one of the world’s leading and most innovative manufacturers in the field of ocular diagnostics, OCULUS is offering a unique combination for this purpose. Sharing the job between them, the OCULUS Pentacam® und OCULUS Corvis® ST are setting new standards in ectasia screening.
The best foundation for your decision
The Tomographic Biomechanical Index (TBI) builds on the specific strengths of the two devices by assessing ectasia risk on the basis of a combined evaluation of the cornea’s biomechanical and geometric data, thus creating a solid foundation for clinical decisions. This gives you the level of safety you need in deciding which patients to accept for surgery.
Drawing on the latest AI know-how, an international group of experts put themselves to the task of refining the algorithm of the TBI. Their work has now made it possible to identify patients with subclinical keratoconus with even greater reliability.
Moreover, thanks to the body of normative data fed into them, the Pentacam® und Corvis® ST also offer you advantages in following up your patients. They enable you to simplify your decision making processes and streamline your workflow.
