A Pentacam is a device that measures the shape and thickness of the anterior eye segment (the front part of the eye) using a rotating camera. It is used for diagnosing and treating eye conditions such as keratoconus, myopia control, cataracts, glaucoma, etc.
A Pentacam is a non-invasive and non-contact diagnostic instrument that provides a 3-dimensional image of the anterior portion of the eye. It works by illuminating a thin layer within the eye. The cells in the eye are not entirely transparent and scatter light and in doing so they create a sectional image that is then photographed. While swiveling around the eye, the camera device generates a series of radially orientated images of the interior eye chamber.
All of the images are put together to create a three-dimensional model of the entire anterior chamber and data regarding the elevation, curvature, pachymetry, depth of the anterior eye chamber and other important information in the well-known form of colour maps.
