An ophthalmological apparatus (1) for treating eye tissue (3) with laser pulses (P) comprises a laser source (100, an optical projection system (20) for projecting the laser pulses (P) onto the eye tissue (30), and a coupling part (12) for attaching mechanically to the optical projection system (20)
An ophthalmological apparatus (1) for treating eye tissue (3) with laser pulses (P) comprises a laser source (100, an optical projection system (20) for projecting the laser pulses (P) onto the eye tissue (30), and a coupling part (12) for attaching mechanically to the optical projection system (20) an ophthalmological patient interface device (27) which is in contact with the eye (3) during treatment. The ophthalmological apparatus (1) further comprises a detector (13) for determining a device identifier (22) associated with the ophthalmological patient interface device (27), and a control module (14) for controlling the ophthalmological apparatus (1) using the device identifier (22). The detector makes it possible to use and detect different types of ophthalmological patient interface devices (27) and to adapt automatically the treatment of the eye tissue (30), depending on the ophthalmological patient interface device (27) that is presently attached to the ophthalmological apparatus (1).
