This vectorial-analysis tool combines several astigmatism components — corneal, lenticular and residual — to derive the power and axis of the resulting cylinder. It provides both a numerical result and a graphical representation, which makes toric-IOL planning and cross-cylinder calculations easier. The often tricky operations of combining oblique cylinders are thus simplified while keeping rigorous mathematical accuracy.
