Fig. 6

Plots of 256 discrete PDφ values of the glass prism (a) and the corneal prism (b), with |PD0| values of 1, 5, 10, 15, and 20 prism diopters (∆). PDφ, prismatic power of the reconstructed round wedge prism with apex angle α0 in an oblique section with angle φ; |PD0|, nominal prism power, corresponding to the absolute value of the prism power, namely, PDφ with φ = 0.
