An ophthalmologic laser device includes a pulsed laser configured to produce radiation focused along at treatment beam path. A variably adjustable beam deflector unit and a focusing lens system are disposed in the treatment beam path. The deflector unit is configured to focus the radiation in different target volumes. Measuring equipment is configured to determine a shape and position of optical interfaces along a detection beam path. A control unit is configured to control the laser and the deflector unit and to implement steps including determining a shape and position of an interface of a membrane of a capsular bag of an eye located in a treatment area using the measuring equipment, determining coordinates of a target volume such that, on irradiation of the target volume, a pressure wave runs from the target volume to the anterior or posterior membrane, and adjusting the deflector unit to the target determined volume.

Methods and systems wherein laser induced refractive index changes by focused femtosecond laser pulses in optical polymeric materials or ocular tissues is performed to address various types of vision correction.

A method and surgical system including a laser source for generating a pulsed laser beam, an imaging system including a detector, shared optics configured for directing the pulsed laser beam to an object to be sampled and confocally deflecting back-reflected light from the object to the detector, a patient interface, through which the pulsed laser beam is directed, the patient interface having, a cup with a large and small opening, and a notched ring inside the cup; and a controller operatively coupled to the laser source, the imaging system and the shared optics, the controller configured to align the eye for procedure.

The amount of energy to provide optical breakdown can be determined based on mapped optical breakdown thresholds of the treatment volume, and the laser energy can be adjusted in response to the mapped breakdown thresholds. The mapping of threshold energies can be combined with depth and lateral calibration in order to determine the location of optical breakdown along the laser beam path for an amount of energy determined based on the mapping. The mapping can be used with look up tables to determine mapped locations from one reference system to another reference system.

Projection of visible, non-treatment light onto an eye to illuminate specific areas of the surgical field is disclosed herein. A surgical system may include a surgical console; a microscope communicatively coupled to the surgical console; a camera communicatively coupled to the surgical console; and a projector operable to project light onto an eye. The projector may be communicatively coupled to the surgical console. A method for light projection may include collecting information from an eye using a camera; determining the light projection based, at least in part, on the collected information; and projecting visible, non-treatment light onto the eye using a projector.

A therapeutic laser for use in treating ophthalmological conditions can be modulated by a spatial light modulation device in order to focus the therapeutic laser on a plurality of target locations simultaneously.

A system for processing a portion in a processing volume of a transparent material by application of focused radiation including a device for generating and an optical system for focusing radiation, with a device for changing the position of the focus of the radiation and a control device. The system includes a controller that controls the ophthalmologic therapy system. The controller is encoded with a scan pattern. The scan pattern includes adjacent strokes with each adjacent stroke having an angle of inclination (?) to the beam axis; and the angle of inclination (?) of the strokes to the beam axis is always larger than or equal to the focal angle (?) of the focused radiation.

An integral laser imaging and treatment apparatus, and associated systems and methods that allow a physician (e.g., a surgeon) to perform laser surgical procedures on an eye structure or a body surface with an integral laser imaging and treatment apparatus disposed at a first (i.e. local) location from a control system disposed at a second (i.e. remote) location, e.g., a physician's office. In some embodiments, communication between the integral laser imaging and treatment apparatus and control system is achieved via the Internet. Also, in some embodiments, the laser imaging and treatment apparatus includes a dynamic imaging system that verifies the identity of a patient, and is capable of being used for other important applications, such as tracking and analyzing trends in a disease process. Further, in some embodiments, the laser imaging and treatment apparatus determines the geographical location of the local laser generation unit of the system using GPS.

An ultrashort pulsed laser instrument is used to perform refractive surgery. The invention operates in ablative and incisional modalities. In the ablative mode, spiral ablation disks consisting of individual laser pulses are produced at high scanning speeds. Ablation profile may be produced in cornea by stacking and arranging multiple ablation disks to produce a specified shape change. Placement of ablation disks is assisted by an optical tracking and control system that compensates for eye motion. A preferred embodiment allows for ablative corrections to be performed on non-planar posterior surface of a laser cut flap affixed to registration platen, thereby avoiding exposing the eye interior to high radiant power. Laser cut and contrast agent dyed fiduciary marks may serve as reference features for the optical tracking system. Incisional procedures, such as corneal flaps for LASIK, may also be performed.

Methods, devices, and systems for reprofiling a surface of a cornea of an eye ablate a portion of the cornea to create an ablation zone with an optically correct central optical zone disposed in a central portion of the cornea, and a blend zone disposed peripherally to the central optical zone and at least partially within an optical zone of the eye. The blend zone can have an optical power that gradually diminishes with increasing radius from the central optical zone.
