Abstract

Software for calculating an astigmatism treatment is operable upon execution to perform the following steps: receiving an initial primary incision position; determining a power and orientation for a toric intraocular lens (IOL) to treat an astigmatism of an eye based on the initial primary incision position; determining an adjusted primary incision position based on the power and the orientation for the toric IOL to further reduce the astigmatism; and generating an output comprising the adjusted primary incision position.
