For the purposes of working on eye tissue, an ophthalmological apparatus comprises a laser source that is configured to produce a pulsed laser beam, a focusing optical unit that is configured to focus the pulsed laser beam into the eye tissue, and a scanner system for deflecting the pulsed laser beam onto work target points in the eye tissue. A circuit controls the scanner system in such a way that the scanner system guides the pulsed laser beam into work trajectories that extend next to one another, in order, initially, to produce cut trajectories, separated by remaining tissue bridges, of a tissue cut to be undertaken in an area and in order, thereafter, to guide the pulsed laser beam in the remaining tissue bridges between the cut trajectories in order to complete the tissue cut.

The invention provides personalized laser probes for use in laser systems, wherein each laser probe includes one or more characteristics tailored to a given user to thereby improve performance of and outcome of a laser treatment procedure.

The invention provides an excimer laser system including a means for calibrating laser output to compensate for increased variation in laser optical fibers.

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.

The invention provides a laser system for performing an intraocular procedure. The laser system includes a single use, disposable laser probe configured to be coupled to a laser source and transmit laser energy from the laser source to a target tissue for treatment thereof. The laser probe comprises a laser transmitting member including a fiber optic core comprising a delivery tip for transmitting laser energy from the laser source to the target tissue during a procedure. The laser probe further includes a light emitting member providing illumination in a field of view proximate to the delivery tip of the fiber core, thereby providing a clear field of view for a surgeon during laser treatment of the target tissue.

A method for detecting structures within an optical element of an eye and processing the optical element as a function of the detected structures includes acquiring, by a detection device, geometric data of an eye, transferring, by the detection device, the geometric data of the eye to a controller, calculating, by the controller, target coordinates for a processing device including a laser, the processing device being connected to the controller, and applying a beam produced by the laser to the eye according to the target coordinates calculated by the controller so as to process the optical element.

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 R.sub.CV* to determine the control data, the cornea reduced by the volume having the radius of curvature R.sub.CV* and the radius of curvature being site-specific and satisfying the following equation: R.sub.CV*(r,φ)=1/((1/R.sub.CV(r,φ))+B.sub.COR(r,φ)/(n.sub.c-1))+F, wherein R.sub.CV(r,φ) is the local radius of curvature of the cornea before the volume is removed, n.sub.c is the refractive index of the material of the cornea, F is a coefficient, and B.sub.COR(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 B.sub.COR(r=r1,φ)≠B.sub.COR(r=r2,φ).

A method and apparatus for performing ophthalmic laser surgery using a pulsed laser beam is provided. The method includes establishing an initial cutting pattern comprising a plurality of original photodisruption points, establishing an enhanced cutting pattern comprising a plurality of enhanced photodisruption points selected to decrease potential adverse effects due to patient movement and having increased density over a fixed area as compared with the plurality of original photodisruption points, and performing an ocular surgical procedure according to the enhanced cutting pattern Enhanced cutting patterns may include circular cuts around the periphery of a capsule, vertical side cuts for lens fragmentation, raster lamellar cuts, and grid lamellar cuts. Each photodisruption point in the initial cutting pattern and the enhanced cutting pattern comprises a laser target point.

A device and a method for producing control data, which are designed to control a laser machining device to surgically correct ametropia of an eye in which, in order to define a space in the cornea, defines a front cutting surface, a rear cutting surface and an edge section, which are to be produced as cutting surfaces in the cornea. The rear cutting surface has a non-circular, oval edge lying in a plane, the edge section connecting the edge to the front cutting surface and the edge section being designed as a non-rotationally symmetrical cylinder or truncated cone, the base of which is the edge.

In certain embodiments, an ophthalmic surgical system for creating a marker in a cornea includes controllable components, a camera, and a computer. The controllable components include a laser source, a scanner, and an objective. The laser source generates a laser beam. The scanner transversely and longitudinally directs a focal point of the laser beam. The objective focuses the focal point towards the eye. The camera images movement of the eye. The computer creates the marker by: instructing the scanner to direct the focal point towards a peripheral region of the cornea; and instructing the controllable components to create the marker in the peripheral region. The computer also determines that movement of the marker is in an alert range indicating an unacceptable amount of movement, and provides notifications in response to determining that the movement of the marker is in the alert range.
