Mapping corneal thickness using dual-scheimpflug imaging at different stages of keratoconus.

Purpose: To map the thickness of the entire cornea using dual-Scheimpflug imaging and to evaluate the changes in the corneal thickness over the entire cornea at different stages of keratoconus.

Methods: Corneal pachymetry was performed using the Galilei dual-Scheimpflug analyzer. The thinnest (TCT), central (CCT), paracentral (PaCT), and peripheral corneal thicknesses (PeCT) were also analyzed.
