Overview
The revolutionary Corvis® ST records the reaction of the cornea to a defined air pulse with a newly developed high-speed Scheimpflug-camera that takes over 4,300 images per second. IOP and corneal thickness can be measured with great precision on the basis of the Scheimpflug images.
Measurement & Display Options
- IOP measurement
- MeasMeasurement 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.)
