Abstract

Only two devices for assessing corneal biomechanics are commercially available, the Ocular Response Analyzer (ORA) and the Corvis ST. Both utilize an air puff as the nondestructive load and both assess biomechanical deformation response of the cornea. However, they differ in strategies for loading with distinct air pressure profiles, as well as for assessing corneal response. The ORA uses an indirect assessment and the Corvis ST uses direct assessment via high-speed imaging. These differences have strong implications on how the data may be interpreted since the corneal biomechanical response depends on the applied load. Details of the differences are discussed in detail, and the devices are directly compared. Each device provides an important and unique biomechanical assessment of the cornea and the data are complimentary rather than competitive in nature.
