Pentacam is a diagnostic device that uses a high-resolution Scheimpflug rotating camera and lighting system that provides accurate and reliable imaging and analysis of structures in the anterior segment of the eye such as the cornea, iris and natural lens.
Pentacam is considered the gold standard for topographic imaging of the cornea. At the same time, with this device, the front and back segment of the eye are recorded and it is determined whether there are certain anomalies in the back of the eye for which there are still no symptoms.
Images take only 2 seconds to obtain and do not require any eye contact. A 3-dimensional virtual model of the anterior segment is then constructed and approximately 25,000 data points are used to calculate corneal topography and anterior and posterior surface elevation, total corneal power, and anterior chamber depth and volume among other parameters. These parameters indicate whether the eye is healthy.
