What is the Principle of Measurement for the Pentacam?

The Pentacam images the anterior segment of the eye by a rotating Scheimpflug camera measurement. This rotating process supplies pictures in three dimensions. The center of the cornea is measured very precisely because of this rotational imaging process. The measurement process lasts less than two seconds and minute eye movements are captured and corrected simultaneously. By measuring 25,000 true elevation points, precise representation, repeatability and analysis are guaranteed.

What is a Scheimpflug Image?

Scheimpflug images are taken from various positions and are accurate 3D-scans of the anterior segment that can be shown.
