Abstract:

 Pentacam Anterior Segment Analysis System shows a 3D image which synthesize from the front surface of the cornea to the post surface of the lens. Anterior and posterior corneal curvature, anterior and posterior corneal elevation, posterior refractive power, corneal astigmatism, corneal volume and corneal thickness measured by the Pentacam Anterior Segment Analysis System play the important roles in diagnosing keratoconus, particular in diagnosing early keratoconus.  (Int Rev Ophthalmol,  2015,  39:     391-393)
