This program is based on the Acrysof Toric Web Based Calculators. It allows the user to calculate the approriate toric lens based on the keratometry and incision location. The iPad version has a lens calculator based on the SRK/T T2 formula.

The calculator allows the user to vary the location and power of the lens to determine the residual predicted refractive error.

A sample database can be downloaded from here.
