Corneal powers measured with a rotating Scheimpflug camera
British Journal of Ophthalmology, 2015Keratometry measures the anterior corneal curvature only. Corneal power is calculated by multiplication with the keratometric refractive index, which takes into account the average negative posterior corneal power. The aim of this study was to calculate and compare various expressions for total corneal power assessed with Scheimpflug camera techniques,

Scheimpflug Camera-Based Systems
2019The Scheimpflug principles enable the capture of focused images of objects that are not parallel to the camera and lens, such as a curved cornea. This is achieved by careful movement of the image and lens planes. In the Pentacam, this is achieved by rotation around a central axis and capture of 50 meridional pictures.

[Scheimpflug photography of the lens].
Fortschritte der Ophthalmologie : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 1989The introduction of Scheimpflug photography of the anterior eye segment, the construction of appropriate equipment, and the development of procedures for image analysis have decisively influenced clinical and experimental research on the anterior eye segment.

Scheimpflug analysis in an epidemiological study
Acta Ophthalmologica, 2015SummaryRadiation cataract enhances age‐related scattering increase. Radiation induces formation of subcapsular and cortical cataracts. Light scattering changes in lens layers evidences radiation damage to lens proteins. Scheimpflug imaging today offers standardized recording procedures minimizing the operator influence.

Galilei Dual Scheimpflug Analyzer
2020Corneal 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,
