Abstract

A patient interface for coupling an ophthalmological application head to an eye of a patient includes a patient-sided interface structure to be coupled to the eye of a patient, and a source-sided interface structure for rigidly coupling the patient interface to the application head or an intermediate element. The source-sided interface structure comprises a first source-sided patient interface coupler and a second source-sided patient interface coupler. The first source-sided patient interface coupler is designed to restrict the mobility of the patient interface relative to the application head or the intermediate element by providing a coupling with a first patient interface coupler counterpiece of the application head or the intermediate element. The second source-sided patient interface coupler is designed to rigidly couple the patient interface to the application head or the intermediate element while the first source-sided patient interface coupler is coupled with the first patient interface coupler counterpiece.
