Abstract:
1. An ophthalmic apparatus comprising: an observation system configured for displaying a moving image of a patient's eye; an optical system for directing an illumination beam into the patient's eye and for directing an observation beam from the patient's eye into the observation system; a control system configured for controlling the optical system; and a control stick for inputting control signal into the control system, wherein the control stick, the control system and the optical system are operatively connected and configured for synchronous real-time conversion of motions of the control stick into motions of the optical system to enable the operator to compensate for motions of the patient's eye such that an alignment of the optical system with the patient's eye is sustained, the control stick including an auxiliary control element being provided on the control stick for inputting auxiliary control signals into the control system; wherein the control system is configured for controlling a display mode of displaying the moving image of the observation system according to the auxiliary control signals, further wherein the auxiliary control element comprises a 2D auxiliary control element configured for inputting 2D directional auxiliary control signals into the control system, wherein the ophthalmic apparatus includes a laser system for a laser treatment of the patient's eye, wherein the control system is configured for controlling the laser system according to the auxiliary control signals input into the control system and the laser system includes a laser steering device for steering a laser beam of the laser system, wherein, to enable the operator to manually steer the laser beam towards treatment areas within the patient's eye by manually operating the 2D auxiliary control element, the control system and the laser steering device are configured for synchronous real-time conversion of motions of the 2D auxiliary control element into motions of the laser steering device.
