Embodiments of the invention provide a method and apparatus for laser-processing a material. In the embodiments, a diffraction-limited beam of pulsed laser radiation is diffracted by a diffraction device to generate a diffracted beam. The diffracted beam is subsequently focused onto the material and is controlled in time and space to irradiate the material at a target position with radiation from a set of radiation pulses of the diffracted beam so that each radiation pulse from the set of radiation pulses is incident at the target position with a cross-sectional portion of the diffracted beam, the cross-sectional portion including a local intensity maximum of the diffracted beam. The beam cross-sectional portions of at least a subset of the pulses of the set include each a different local intensity maxi-mum. In this way, a multi-pulse application for generating a photo-disruption at a target location of the material can be implemented.

A method of performing laser surgery in a patient's eye includes generating a light beam, deflecting the light beam using a scanner to form an enclosed treatment pattern that is configured to form an enclosed capsulorhexis incision that includes a registration feature, and delivering the enclosed treatment pattern to target tissue in the patient's eye to form in an anterior lens capsule of the patient's eye the enclosed capsulorhexis incision that includes the registration feature. The registration feature is configured so that an edge of the target tissue formed by the enclosed capsulorhexis incision mates with an intraocular lens registration feature on an intraocular lens so as to rotationally register the intraocular lens relative to the registration feature.

An ophthalmic laser system includes a laser engine to generate a beam of femtosecond laser pulses, a laser scanner to scan each laser pulse of the beam in three dimensions according to a scan pattern, and a compound lens comprising a glass lens and a birefringent lens, the compound lens arranged to receive the scanned beam and configured to split each laser pulse of the scanned beam into an ordinary pulse and an extraordinary pulse, producing an ordinary beam comprising ordinary pulses and an extraordinary beam comprising extraordinary pulses. A particular ordinary pulse and a particular extraordinary pulse split from a particular laser pulse are spatially separated in depth along an optical axis of the compound lens, by a distance greater than or equal to 5 m, and temporally separated by a delay greater than or equal to a pulse duration of the femtosecond laser pulses. An objective is configured to focus the ordinary beam and the extraordinary beam within an ophthalmic target.

An ophthalmological laser therapy system having an appliance base and an appliance head, displaceable relative to one another by translational movement and having a laser device and to a corresponding method. A laser pivot arm is fastened to the appliance head pivotable about a horizontal first axis. The laser pivot arm is encompassed by a pivot arm housing, which is fastened in a separately pivotable manner on the appliance head in coaxial fashion relative to the laser pivot arm and/or by virtue of an examination pivot arm with an examination device, defining an examination volume, being fastened to the appliance head pivotable about a second axis, wherein both axes are arranged such that a work volume of a laser beam, when the laser pivot arm is in a work position, is a partial volume of the examination volume, when the examination pivot arm is in a work position.

A system for short pulse laser eye surgery and a short pulse laser system, in which a beam guidance device passes through a corresponding articulated arm, and through an applicator head and a microscope head of the system, which is movable in a three-dimensional volume both independently of one another as well as connected to each other. The system also includes an easy to use patient interface with a one-piece contact element, a computer program product for methods of the incision guidance and sequentially operating referencing methods with patient interfaces containing markings.

In certain embodiments, a patient interface for an ophthalmic laser system comprises an interface portion and an attachment portion. The interface portion comprises a contact portion, a cone wall, and one or more structures. The contact portion has an abutment face that is configured to be in contact with the cornea of an eye. The cone wall is disposed outwardly from the contact portion and defines a cone interior. The cone wall has an inner surface and an outer surface, where the inner surface defines the cone interior. The cone wall has an upper portion and a lower portion, where the lower portion is coupled to the contact portion. The one or more structures direct light from the cone wall towards the cone interior. The attachment portion affixes the interface portion to the cornea of the eye.

Images of a patient's eye can be imaged and the images processed to detect and track floaters within the patient's eye. The floater detection and tracking can be used to identify characteristics of the floaters as well as possibly perform laser treatment of the floaters.

Systems and methods automatically locate optical surfaces of an eye and automatically generate surface models of the optical surfaces. A method includes OCT scanning of an eye. Returning portions of a sample beam are processed to locate a point on the optical surface and first locations on the optical surface within a first radial distance of the point. A first surface model of the optical surface is generated based on the location of the point and the first locations. Returning portions of the sample beam are processed so as to detect second locations on the optical surface beyond the first radial distance and within a second radial distance from the point. A second surface model of the optical surface is generated based on the location of the point on the optical surface and the first and second locations on the optical surface.

Embodiments of this invention generally relate to ophthalmic laser procedures and, more particularly, to systems and methods for creating synchronized three-dimensional laser incisions. In an embodiment, an ophthalmic surgical laser system comprises a laser delivery system for delivering a pulsed laser beam to a target in a subject's eye, an XY-scan device to deflect the pulsed laser beam, a Z-scan device to modify a depth of a focus of the pulsed laser beam, and a controller configured to synchronize an oscillation of the XY-scan device and an oscillation of the Z-device to form an angled three-dimensional laser tissue dissection.
