Abstract: The present disclosure provides a system and method for maintaining the position of a suction cone on an eye during laser ophthalmic surgery that includes determining a distance and direction the suction cone or a support must be adjusted to maintain the position of the suction cone within an optimal working range, based on a detected position of the suction cone. The disclosure further provides a method for maintaining the position of a suction cone by determining a distance and direction the suction cone or a support must be adjusted to maintain the position of the suction cone within an optimal working range, based on a detected position of the suction cone. In the system and the method, a control signal is generated to adjust the position of the suction cone and/or the support to maintain the suction cone within the optimal working range.

Abstract: According to certain embodiments, a system comprises one or more memories and one or more processors. The one or more memories store optical data from an optical recorder comprising at least two optical data sets by: receiving a first optical data set of an eye with a pupil having a first pupil size; and receiving a second optical data set of the eye with the pupil having a second pupil size. The one or more processors determine a pseudo-rotation related to a pupil size change, receive a measured cyclotorsion, calculate an actual cyclotorsion from the measured cyclotorsion and the pseudo-rotation, and adjust a laser treatment according to the actual cyclotorsion.

Abstract: A method for testing a laser device configured to emit pulsed, focused laser radiation includes providing an artificial eye body with a pattern that simulates a pupil and/or an iris structure. An irradiation test object is arranged above the pattern. The irradiation test object is separate from the eye body and is made of a material that is modifiable by the laser radiation. The laser radiation is applied to the irradiation test object according to a predefined application profile, so that a material modification that corresponds to the application profile is generated in the irradiation test object.

Abstract: The present disclosure provides a system for automated fine adjustment of an ophthalmic surgery support in which an eye tracking system detects a detectable position of an eye. The direction and distance the support must be adjusted for the eye to be centered may be determined based on the detectable position. A control signal is generated and transmitted to a control device that adjusts the position of the support to center the eye. The disclosure further provides a method for automated fine adjustment of a support, which includes detecting a detectable position of an eye, determining whether the eye is centered in relation to the center of the detection field of an eye tracking system based on the detectable position, determining a direction and a distance the detectable position must be adjusted to be centered, and generating and transmitting a control signal to adjust the position of the support.

Abstract: Methods and systems for overlay imaging for registration of a patient eye for laser surgery include aligning and overlaying a surgical image of the limbus over a previously acquired diagnostic image of the limbus. The surgical image is displayed with a degree of transparency and enabled to rotate about the limbus center. Various types of colors, markers, contrast, and backgrounds may be used to generate a display for determining the alignment angle between the diagnostic image and the surgical image.

Abstract: 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.

Abstract: An ophthalmic laser processing apparatus comprises: a laser device that outputs a pulsed laser beam towards an eye; an image capturing device that captures an image of the eye and provides image data; and a control device that detects eye movement based on the image data and controls the beam focus based on a predetermined eye processing pattern and the eye movement. The apparatus further comprises a visualization device controlled by the control device to output a visualization of a graphical illustration. The graphical illustration represents at least one of (a) a value of an eye parameter determined on the basis of the image data; (b) a frequency distribution of a value of an eye parameter determined on the basis of the image data; and (c) a range of values of a pupil diameter determined on the basis of the image data.
