Pentacam: Principle and Clinical Applications

Current Journal of Glaucoma Practice with DVD, 2009
Rotating Scheimpflug imaging technology is used by instruments such as the Pentacam (Oculus) to measure the anterior and posterior corneal surfaces, as well as other anterior segment structures. Initially, Scheimpflug photography was used to obtain images of lens opacities for objective evaluation, but Pentacam-Scheimpflug camera is much wider in its ...
