Apparatus for treating eye tissue with laser pulses

摘要

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).

1. An ophthalmological apparatus for treating eye tissue with laser pulses, comprising:
a laser source configured to generate the laser pulses, an optical projection system configured to project the laser pulses onto the eye tissue, a focusing system comprising optical systems and a driver system coupled to the optical systems and configured to adjust the optical systems, such that the laser pulses are projected onto a defined projection surface and focused on this projection surface with a spot having a defined spot size; a coupling part configured to attach mechanically to the optical projection system an ophthalmological patient interface device which is in contact with the eye during treatment, a detector configured to determine a device identifier associated with the ophthalmological patient interface device currently attached to the optical projection system, and a control module comprising a plurality of different zooming functions, each zooming function being configured to control the focusing system to project the laser pulses onto a defined projection surface located at a defined depth and to focus the laser pulses onto the defined projection surface with a defined spot size, the control module further comprising a processor or hardware modules configured (a) to implement the plurality of different zooming functions, each of the plurality of different zooming functions being configured to transmit to the focusing system control signals via a signaling interface to control the driver system to adjust the optical systems, and (b) to control the ophthalmological apparatus by selecting a particular zooming function from the plurality of different zooming functions based on the device identifier of the ophthalmological patient interface device currently attached to the optical projection system, the device identifier being received or read from the detector to select the particular zooming function, the particular zooming function being configured both to control the focusing system to project the laser pulses onto a defined projection surface of the particular zooming function, and to focus the laser pulses on the defined projection surface of the particular zooming function with the defined spot size of the particular zooming function.
