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 thinnest point
- D – distance-corrected visual acuity
While older models focused only on anterior curvature and central corneal thickness to assess abnormalities, the ABCD system provides a broader view of the cornea using advanced tomographic data.
The Belin ABCD Progression Display offers valuable insight into structural and visual changes in the cornea over time. This assists eye care professionals in evaluating and documenting changes, particularly when managing patients who may be at risk for progressive corneal conditions.
