The disclosure relates to systems and methods for performing eye surgery in which a single image that simultaneously presents a graphical representation of a planned or actual flap location superimposed with a graphical representation of a planned or actual area of ablation is used.

System for performing eye surgery with simultaneous display of graphical information for flap and ablation

The present disclosure provides a system for femtosecond ophthalmic surgery in which the position of a suction cone in the z direction is measured via the measuring device to generate data that is processed and used to create a pictorial representation, a histogram, or other graph based on the data. The pictorial representation may include at least one threshold marker. The disclosure further provides a method of performing docking in femtosecond laser ophthalmic surgery including measuring the position of a suction cone with a measuring device, and transmitting data regarding the position to a processor which processes the data and uses it to create a pictorial representation, histogram, or other graph that is presented on a display.

The present disclosure provides a system and method for indirectly determining weight on eye, the weight resulting from contact between the eye and a docking apparatus for laser ophthalmic surgery. The system includes a docking apparatus, a measuring device, a display and a processor that determines a relative distance between a detectable position of a component of the docking apparatus and a neutral position of the eye, determines the weight on eye by reference to sensed force-distance reference data, and generates and transmits a pictorial representation of weight on eye to a display. The disclosure further provides a method for indirectly determining weight on eye, the weight resulting from contact between the eye and a docking apparatus for laser ophthalmic surgery.

A process is proposed for testing a laser device that has been set up to emit pulsed focused laser radiation, the focal position of which is adjustable both in and across the direction of propagation of the laser radiation. The laser device includes a contact element that is transparent to the laser radiation, with an abutment surface for abutment of an object to be machined. Within the scope of the process, a test object that is transparent to the laser radiation at least in a machining region is applied onto the abutment surface of the contact element. Then laser radiation is beamed into the test object bearing against the abutment surface and in the process the focal position is moved in accordance with a predetermined test pattern, in order to generate enduring machining structures in the test object.
