1. A laser eye surgery system comprising:
a patient interface including a suction ring having a vacuum chamber configured to engage a patient's eye, the patient interface further including a transmissive lens which defines a space between the patient's eye and a posterior surface of the transmissive lens configured to contain a sterile solution;
a laser source configured to generate a laser beam;
an optical system configured to deliver a focus of the laser beam to the eye;
a video camera configured to capture images of the eye through the patient interface and to generate image data based thereon;
one or more physical force sensors configured to detect movement of the patient's eye relative to the patient interface and to generate force data based thereon;
a vacuum sensor connected to the vacuum chamber of the suction ring, configured to sense a pressure in the vacuum chamber of the suction ring and to generate pressure data based thereon; and
control electronics coupled to the laser source, the optical system, the video camera, the one or more physical force sensors, and the vacuum sensor, configured to aggregate the image data, the force data and the pressure data, and to halt or delay delivery of the focus of laser beam to the eye if at least two of the image data, the force data and the pressure data are consistent with a threshold likelihood of a vacuum leak.
