Figure 2

Corvis ST biomechanical/tomographic assessment of a keratoconic eye. Biomechanical assessment shows increase in DA ratio and integrated radius, and decrease in ARTh and SP-A1 (top left). Tomographic assessment shows central corneal thinning with an asymmetric bow tie pattern (top right). The percentage of thickness increase (PTI) graph shows an inferior escape from the normal mean. CBI, TBI, and BAD are all increased (bottom).
