Ophthalmological laser therapy system

An ophthalmological laser therapy system comprising:

• an appliance base,
• an appliance head,
• a laser device including a laser source, a first laser therapy optical unit and a laser pivot arm with a second laser therapy optical unit and a laser exit aperture,
• wherein
• the appliance head is displaceable on the appliance base in an x-y-plane by a translational movement,
• the laser pivot arm is coupled to the appliance head to be pivotable about a first axis;
• and
• the ophthalmological laser therapy system further comprising a pre-positioning device that pre-positions the appliance head.

A method for pre-positioning an ophthalmological laser therapy system, comprising:

• placing a patient onto a patient support adjacent an ophthalmological laser therapy system comprising:
• an appliance base,
• an appliance head,
• a laser device that includes a laser source, a first laser therapy optical unit and a laser pivot arm with a second laser therapy optical unit and a laser exit aperture,
• wherein
• the appliance head is displaceable on the appliance base in an x-y-plane by a translational movement and
• the laser pivot arm is coupled to the appliance head in a manner pivotable about a first axis between a laser rest position and a laser work position,
• wherein, when the laser pivot arm is in the rest position, the method further comprises:
• pre-positioning the appliance head by application of a pre-positioning device, such that the laser pivot arm after pivoting-down into the work position is in an ideal position for a laser treatment start in respect of an approximate positioning, and only fine positioning in respect of structures of the eye is still necessary.
