Galilei Dual Scheimpflug Analyzer

Corneal topography is the most commonly used imaging technology for evaluating the anterior corneal surface. Scheimpflug imaging is a newer technology that permits evaluation of both the anterior and posterior surfaces of the cornea and provides three-dimensional reconstruction of the cornea. The Galilei dual Scheimpflug analyzer (software version 5.2, Ziemer Ophthalmic Systems AG, Port, Switzerland) incorporates two important diagnostic modalities, including Placido imaging which supplies high precision curvature data and a revolving dual channel Scheimpflug camera which is optimal for the accurate acquisition of elevation data. The combination of Placido topography with Scheimpflug imaging improves the accuracy of the central anterior corneal curvature measurement and provides an accurate three dimensional analysis of the cornea and anterior eye segment.
