Provided herein are alignment systems, computer-implemented systems and methods utilizing the same for planning an optimal surgical implantation of asymmetric optics into one or both eyes of a patient and/or correcting astigmatism thereof. The methods generally comprise obtaining reference data comprising the surgical procedure plan, the reference image and the corneal topographic measurements for the patient's eye, determining an optimal placement angle of an optical zone on the cornea from the reference data and placing the asymmetric optic into the eye to match the determined optimal placement angle. Particularly, software is configured to determine the rotational difference between a reference image and a live image of the patient's eye to determine a corrected axis angle for optimal placement angle which is superimposed over a display of the live image. Also provided are non-transitory computer-readable medium and computer program products embodied with software for planning the surgical implantation. |
