The Belin ABCD Staging Display is a modern tool designed to support the comprehensive assessment of corneal shape and thickness by incorporating multiple parameters: A – anterior corneal curvature B – posterior corneal curvature C – corneal thickness at the ...

If the patient’s refraction is hyperopic – regardless of amount – the Hyperope option should be activated. The reason for this is that normative data for posterior elevation differs between myopes and hyperopes.

The Belin/Ambrosio Display (BAD) is designed as a screening tool to assess corneal elevation and curvature patterns, particularly in patients being evaluated for refractive procedures. The most important parameter is the “Final D”. The other 5 parameters contribute to the ...

In the BAD, all the curvature data for a specific diameter are used to calculate the radius of a reference surface (BFS) to evaluate height data – this supports the detection of suspicious elevation in the anterior and the posterior ...
