1. A system for photodisrupting a target volume of ocular tissue with a laser, the target volume of ocular tissue associated with an eye of a patient, the system comprising:
a first optical subsystem including one or more optical components configured to be coupled to the eye;
a second optical subsystem including a laser source configured to output a laser beam, and a plurality of components optically coupled between the laser source and the first optical subsystem; and
a control system coupled to the first optical subsystem and the second optical subsystem and configured to:
derive an initial coordinate set based on a function that is based on data of the patient including a central corneal thickness (CCT), a white-to-white (W2W) diameter at a meridian of a cornea of the eye, and an anterior cornea radius of curvature Ra at the meridian of the cornea of the eye, the initial coordinate set corresponding to an initial location within a target volume of ocular tissue;
determine an energy parameter from a database that maps a plurality of coordinate sets of locations within the target volume of ocular tissue, including the initial coordinate set, to energy parameters;
control the laser source to output a laser beam, and the plurality of components to place a focus of the laser beam at the initial location within the target volume of ocular tissue; and
control the second optical subsystem to apply photodisruptive energy by the laser beam at the initial location in accordance with the energy parameter.
