1. An ophthalmic surgical system, comprising:
a robotic arm disposed above a patient's eye;
a positioning camera disposed on the robotic arm and positioned to visualize the patient's eye;
a processor electrically coupled to the positioning camera, the processor being configured to:
receive an indication of a position of the robotic arm relative to a fixed datum;
determine a focal length between the positioning camera and the patient's eye;
determine a patient eye level relative to the fixed datum by comparing the focal length to the position of the robotic arm; and
determine an intraocular pressure set point based on the patient eye level.
