Detailed Information

Corneal Visualization Scheimpflug Technology

The revolutionary Corvis® ST records the reaction of the cornea to a defined air pulse using a newly developed high-speed Scheimpflug camera. This camera captures over 4 300 images per second, permitting highly precise measurement of IOP and corneal thickness. Based on a video of 140 images, taken within 31 ms after onset of the air pulse, the Corvis® ST provides a detailed assessment of corneal biomechanical properties.
The information obtained on the biomechanical response of the cornea is used to calculate a biomechanically corrected IOP (bIOP). Furthermore it allows ectatic diseases such as keratoconus to be detected at a very early stage. Biomechanical properties also play an important role in the development and progression of glaucoma.


Dynamic Corneal Response

The DCR Display gives you various insights into the biomechanical properties of the cornea. The software provides detailed analysis of the Scheimpflug images taken during deformation of the cornea. The parameters which describe the deformation characteristics give information about corneal biomechanics. Also included are the Corvis Biomechanical Index (CBI) and Tomographic Biomechanical Index (TBI).


This new function allows you to email values for intraocular pressure and corneal thickness as well as impressive videos to your patients. Videos include a feature for reminding patients of upcoming follow-up exams. This way you can convince them – in particular the young ones – of the necessity for glaucoma screenings and regular follow-up exams. The high-end diagnostics provided by the Corvis® ST will put the focus on your performance and high-tech equipment.


Measurement and Display Options

  • IOP measurement
  • Measurement of the corneal thickness
  • Scheimpflug images of the 1st and 2nd applanation of the cornea
  • Slow-motion video of the corneal deformation as a result of the air pulse
  • Non-contact tonometer in combination with an ultra-high-speed camera for visualization of the deformation of the cornea in reaction to an air pulse (4 330 frames / sec.)
