Abstract

This review looks at biomechanical concepts and misconceptions related to in vivo assessment of corneal biomechanical response via air-puff deformation, including both human donor corneas and the translation of similar concepts to clinical studies. The impact of corneal viscoelasticity on interpreting clinical data is discussed, as well as the differences between 2 clinical devices that produce air puffs with distinct temporal and magnitude profiles.
