Abstract: An ophthalmic laser system and related method for forming a lenticular incision in a corneal lenticule extraction procedure. The lenticular incision is formed by multiple sweeps of a laser scan line along meridians of longitude of the lenticular incision, where the end point of each sweep is connected to the start point of the next sweep by a smooth turning trajectory. The trajectory includes a first circular arc tangentially connected to the first sweep at its end point, a second circular arc tangentially connected to the next sweep at its start point, and a straight line segment tangentially connected to both circular arcs. The smooth trajectory is determined with the given limits of velocity, acceleration and jerk of the XY scanning motors, without using high frequency filters to smooth the trajectory, thereby avoiding unknown changes to the original trajectory and achieving high precision lenticule shapes.

Abstract: A first image of the eye is generated when the cornea of the eye is exposed to a gas. The cornea is covered with an optic of a patient interface. A second image of the eye with the patient interface over the cornea is generated. In this second image, the patient interface distorts the second image of the eye. One or more of a position or an orientation of the eye is determined in response to the first image and the second image when the patient interface has been placed over the cornea.

Abstract: A device for producing control data for a laser device for the surgical correction of defective vision. The device produces the control data such that the laser emits the laser radiation such that a volume in the cornea is isolated. The device calculates a radius of curvature RCV* to determine the control data, the cornea reduced by the volume having the radius of curvature RCV* and the radius of curvature being site-specific and satisfying the following equation: RCV*(r,φ)=1/((1/RCV(r,φ))+BCOR(r,φ)/(nc−1))+F, wherein RCV(r,φ) is the local radius of curvature of the cornea before the volume is removed, nc is the refractive index of the material of the cornea, F is a coefficient, and BCOR(r,φ) is the local change in refractive force required for the desired correction of defective vision in a plane lying in the vertex of the cornea, and at least two radii r1 and r2 satisfy the equation BCOR(r=r1,φ)≠BCOR(r=r2,φ).

Abstract: The invention relates to a method for providing control data for an ophthalmological laser (12) of a treatment apparatus (10) for avoiding optical aberrations. As the steps, the method includes ascertaining (S10) first aberration values from a predetermined wavefront measurement of an eye, which has a first extension (32), wherein a first refractive power error is determined from the first aberration values; ascertaining (S12) second aberration values from a subset of the predetermined wavefront measurement, which has a second extension (34), wherein the second extension (34) is smaller than the first extension (32), wherein a second refractive power error is determined from the second aberration values; ascertaining (S14) a difference between the first and the second refractive power error; ascertaining (S16) an aberration-corrected refractive power change by subtracting the ascertained difference of refractive power errors from a predetermined subjective refractive power correction, which is predetermined from a glasses correction measurement; and providing (S18) the control data for the ophthalmological laser (12), which includes the aberration-corrected refractive power change.

Abstract: A method for forming an incision in an eye, the method including performing a first pass of a first laser beam along a path within an eye, wherein after completion of the first pass there exists a residual uncut layer at an anterior surface of a cornea of the eye. The method further including performing a second pass of a second laser beam only along a portion of the path that contains the residual uncut layer, wherein after completion of the second pass, the residual uncut layer is transformed into a full complete through surface incision.

Abstract: A method of imaging and treating ocular tissue of an eye having a cornea, an iris, an anterior chamber, an irido-corneal angle, and a direction of view includes establishing a common optical path through the cornea and the anterior chamber into the irido-corneal angle for each of an optical coherence tomography (OCT) beam and a laser beam, where the common optical path is offset from an optical axis within the direction of view. The method also includes obtaining a circumferential OCT image of the irido-corneal angle, obtaining an azimuthal OCT image of the irido-corneal angle, and determining a treatment pattern for a volume of ocular tissue of the irido-corneal angle based on the circumferential OCT image and the azimuthal OCT image. The method further includes delivering optical energy through the laser beam in accordance with the treatment pattern.

Abstract: The claimed embodiments relate to methods for characterizing a laser beam (24) of a laser processing system (30). The method includes a) providing an aperture arrangement (10) with a plurality of apertures (14) in a work plane (300) of the laser processing system (30) such that the apertures (14) extend within the work plane (300). The method also includes b) scanning the laser beam (24) along a scanning direction (200) parallel to the work plane (300) across the aperture arrangement (10) in such a way that the laser beam (24) at least partially sweeps over the apertures (14). The method also includes c) determining a respective energy of the laser beam (24) transmitted through the apertures (14) during the scanning process, and d) determining an extent of the laser beam (24) along the scanning direction (200) using the determined energy of the laser beam (24) transmitted through a first aperture (14a) of the plurality of apertures (14) and determining an energy parameter of the laser beam (24) on the basis of the determined energy of the laser beam (24) transmitted through a second aperture (14b) of the plurality of apertures (14). In this case, the first aperture (14a) has a predetermined extent along the scanning direction (200), which is smaller than the mean diameter of the laser beam (24) in the work plane (300). In addition, a second aperture (14b) has an extent that is larger than the laser beam (24) in the work plane (300) and is designed to transmit the laser beam (24) essentially completely.

Abstract: A system for therapy of the eye by treating tissue with therapeutic radiation using nonlinear interaction. A laser device is provided, which delivers the therapeutic radiation. The therapeutic radiation is focussed by a focussing device in an image field, and xy scanners and z scanners shift the focus laterally and longitudinally within a treatment volume. The therapeutic radiation is either a second short pulse radiation or a first short pulse radiation, each of which have a spectral centroid within a wavelength range defined by the short pulse properties. The system is particularly corrected with regard to longitudinal chromatic aberrations and lateral chromatic aberrations such that the spectral characteristic curves of the two aberrations each have a local extreme within the wavelength ranges, and a certain tolerance within the wavelength ranges is not exceeded, therefore the characteristic curves are very shallow.
