CORVIS ST – Corneal Visualization Scheimpflug Technology.

Corvis ST is a little sensation! There is no comparable device on the World’s market!

The Corvis ST is a NonContactTonometer and allows seeing the reaction of the cornea on an air impulse. An ultraspeed Scheimpflug camera (4330 frames/sec.) records the movements of the cornea which then are displayed on the builtin control panel in ultraslowmo. So far unseen pictures allow exciting new ways in the assessment of corneal properties for various applications from Keratoconus screening to Glaucoma.


IOPMeasurements with the Corvis ST The Corvis ST measures the IOP, corneal thickness and biomechanical properties. Based on these data, it has the potential to determine a highly accurate value close to the "True IOP". It determines the influence of the biomechanical properties on conventional IOP measurements.

Screening for corneal ectasia with the Corvis ST Both, stiffness and viscosity of the cornea, are reduced by ectasia.Both effects can be analyzed simultaneously with the Corvis ST.

Visualizing the effect of corneal crosslinking with the Corvis ST With the Corvis ST it is possible to visualize the effect of corneal crosslinking on the deformation characteristics. The Corvis ST has the potential to quantify the effect of corneal crosslinking on the biomechanical properties.

Measurement Features and Possibilities:

  • Calculate Corneal Properties from Deformation characteristics. 
  •  Applanation length. 
  • Corneal velocity and thickness. 
  • Calculate Intra Ocular Pressure with knowledge of properties.
  •  Identify patients at risk for ectasia. 
  • Improve Prediction of Refractive outcomes. 
  • Visualize the effect of corneal crosslinking. 
  • Biomechanical risk factors in glaucoma. 
  • Scheimpflug images of applanation moments 1, 2 and of the highest concavity of the cornea. 
  • Slowmotion video of the corneal deformation after air pulse.
