Detection of ectatic corneal diseases based on pentacam

open access: yesZeitschrift für Medizinische Physik, 2016
Pentacam is a rotating Scheimpflug-based corneal and anterior segment tomographer that gives as comprehensive analysis of corneal 3D geometry. With this device the detection of mild keratoconus or ectasia susceptibility is possible. This is fundamental for screening ectasia risk prior to laser vision correction.
