Pentacam camera is used to measure the front part of the eye. The measurment is contactless and takes about 2-4 seconds. With the help of a rotating Scheimpflug camera, it is possible to map the topography of the anterior surface of the cornea, measure the thickness of the entire cornea, the radius of the cornea, the asphericity of the cornea, the curvatures of both the inner and outer cornea. The camera also analyzes the anterior chamber of the cornea, its depth and volume, and measure the transparency and thickness.
