Abstract
An ophthalmic surgical system includes a robotic arm disposed above a patient's eye. A positioning camera is disposed on the robotic arm and positioned to visualize the patient's eye. A processor is electrically coupled to the positioning camera. The processor is 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, compare the focal length to the position of the robotic arm, and determine a patient eye level relative to the fixed datum.
Claims19
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.
A surgical microscope, comprising:
- a positioning camera positioned to visualize a patient's eye;
- an encoder coupled to the positioning camera, the encoder being configured to determine a position of the positioning camera relative to a fixed datum;
- a processor electrically coupled to the encoder and the positioning camera, the processor being configured to:
- receive an indication of a position of the positioning camera relative to the 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 positioning camera;
- and
- determine an intraocular pressure set point based on the patient eye level.
A method of determining patient eye level, the method comprising:
- focusing a positioning camera on a patient's eye;
- determining a position of the positioning camera relative to a fixed datum;
- determining a focal length between the positioning camera and the patient's eye;
- determining the patient eye level by comparing the focal length to the position of the positioning camera relative to the fixed datum;
- and
- determining an intraocular pressure set point based on the patient eye level.
