Methods and systems wherein laser induced refractive index changes by focused femtosecond laser pulses in optical tissues is performed in combination with corneal lenticular surgery to achieve overall desired vision corrections.

The present invention relates to the field of devices for correcting or mitigating refractive errors in the eye, more particularly, to a solution in which desired improvements in eyesight are achieved as far as possible without limiting everyday activities and where performing the treatment itself involves minimum risk by use of a device for creating an aperture in an eye, the device having a control unit for a laser unit, and the control unit is designed to control the laser unit to create the aperture in a lens of the eye, wherein the aperture is used to increase the depth of field of the eye and is formed by laser-induced lesions which reduce light transmission through a lens aperture region surrounding an aperture opening.

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.

A treatment method and apparatus for surgical correction of defective-eyesight in an eye of a patient, wherein a laser device is controlled by a control device, said laser device separating corneal tissue by irradiation of laser radiation to isolate a volume located within a cornea, wherein the control device controls the laser device to focus the laser radiation, by providing target points located within the cornea, into the cornea, wherein the control device, when providing the target points, allows for focus position errors which lead to a deviation between the predetermined position and the actual position of the target points when focusing the laser radiation, by pre-offsets depending on the positions of the respective target points to compensate for said focus position errors.

A method for adjusting the refractive power of a fluid-filled intraocular lens implanted into a patients eye. The method comprises selecting a pattern to cause a flattening of the intraocular lens or an increase in curvature of the intraocular lens, and ablating the pattern, onto either an optical element of the intraocular lens or a flexible element of the intraocular lens, to alter either one or both of a refractive power and an amplitude of accommodation of the intraocular lens. The ablating occurs while the intraocular lens remains implanted in the patient's eye. The ablating maintains the integrity of a fluid-filled interior cavity defined between the optical element and the flexible element, but causes the flattening of the intraocular lens or the increase in curvature of the intraocular lens.

A method of generating three dimensional shapes for a cornea and lens of an eye, the method including illuminating an eye with multiple sections of light and obtaining multiple sectional images of said eye based on said multiple sections of light. For each one of the obtained multiple sectional images, the following processes are performed: a) automatically identifying arcs, in two-dimensional space, corresponding to anterior and posterior corneal and lens surfaces of the eye by image analysis and curve fitting of the one of the obtained multiple sectional images; and b) determining an intersection of lines ray traced back from the identified arcs in two-dimensional space with a known position of a section of space containing the section of light that generated the one of the obtained multiple sectional images, wherein the determined intersection defines a three-dimensional arc curve. The method further including reconstructing three-dimensional shapes of the anterior and posterior cornea surfaces and the anterior and posterior lens surfaces based on fitting the three-dimensional arc curve to a three-dimensional shape.

A reconfigurable laser-ultrasound, including femto-phaco, femto-phaco system having different configurations and positions of a laser delivery head, and having a single laser beam path length for all configurations. Integrated systems and methods for performing laser and phacoemulsification operations. A reconfigurable system for performing a laser procedure in a laser configuration, and then being reconfigured into a phaco configuration, to perform a phacoemulsification, and then being reconfigured back to the laser configuration.

A treatment device for the surgical correction of defective vision in an eye. The device includes a laser apparatus controlled by a controller. The controller determines a desired correction of defective vision from measurement data of the eye to produce control data for the laser, and to control the laser to emit radiation according to the control data, such that a lenticule-shaped volume is isolated in the cornea. The controller computes a lenticule-shaped intended volume, the removal of which from the cornea leads to an actual correction of defective vision in an optical zone in the eye which differs from the desired correction more at the edge of the optical zone than at the center of the optical zone. The thickness of the lenticule-shaped intended volume is less than the thickness of a lenticule-shaped comparison volume, the removal of which would bring about the desired correction of defective vision.
