1. A laser eye surgery system comprising:
a moveable patient support adapted to support a patient;
a patient interface assembly including:
a housing;
a patient interface configured to be coupled to an eye of the patient, partly disposed within the housing and moveable vertically relative to the housing; and
a linear encoder configured to determine a vertical position of the patient interface relative to the housing;
a laser system configured to deliver a laser focus point to laser target locations within the eye; and
a controller coupled to the patient support, the patient interface assembly and the laser system, configured to:
move the patient support or the patient interface or both vertically;
track a vertical position of the patient interface using the linear encoder;
limit movements of the patient support or the patient interface based on the tracked vertical position of the patient interface.
