Non-contact tonometer with high-speed camera

The OCULUS Corvis ST is a new non-contact tonometer in combination with an ultra-high-speed Scheimpflug camera (more than 4000 images/sec) that can visualise the reaction of the cornea on an air impulse.

OCULUS say conclusions can be drawn regarding the bio-mechanical properties from the response of the cornea after the air impulse. “It is well known that IOP-measurements by Goldmann Applanation Tonometry (GAT) and Non-Contact Tonometry (NCT) are influenced by the corneal thickness of the cornea. It is not very well known that the IOP-measurements are even more affected by the biomechanical properties of the cornea,†said an OCULUS spokeswoman.

The OCULUS Corvis® will be for sale from spring 2012. The device is not for sale in the US yet with FDA 510K pending.
