Abstract:
1. A surgical excimer laser treatment system, comprising: a controller configured to direct excimer laser output of three dimensional presby ablation profiles for treating emmetropic and/or ametropic presbyopes; and an excimer laser in communication with the controller configured to ablate a cornea of an eye of respective patients based on instructions from the controller to transmit a defined three-dimensional multifocal presby ablation profile using a single activation of the surgical laser system to treat presbyopia and provide near and distance vision acuity in the same eye, wherein the instructions from the controller comprise ablation depth versus distance from a center of the cornea for the three dimensional presby ablation profile determined using a defined mathematical equation, and wherein the equation determines ablation depth for a respective distance using a parameter for myopic correction having a set of ablation depths versus distances from the center of the cornea and a parameter for hyperopic correction having a set of ablation depths versus distances from the center of the cornea.
