Refraction (Post-Lasik Ref., in diopters) after the Refractive Surgery, accordingly the selected correction type.
Pre-Lasik Ref. must be negative for Myopic Lasik and Radial Keratotomy corrections, while must be positive

Otherwise select “No History” if pre and post refractive surgery measurements are not available in order to

After having selected the toric IOL model, a values table from which the Spherical Equivalent Power is
obtained. Once you choose a lens, pressing “Next” at the bottom right, you enter in the second-step of True
K toric IOL calculation (Figure 58).
Figure 58
As a result, the “True K Toric” frame, immediately below, details the best toric lens computed automatically
by the system for the manufacturer and model selected previously in the first-step.
From “Available Toric Lenses” table you can choose also a different cylinder value for the lens, based on the
Residual Astigmatism you want to achieve (under-correction/overcorrection). In particular, the best toric lens
