Abstract: Systems and methods are disclosed for a surgical laser system with illumination. In some embodiments, a laser system comprises a surgical laser and an illumination source having their outputs combined into a fiber-optic cable and directed by the fiber-optic cable to a target surface. The illuminating visible light may be continuous and/or in pulses. Surgical laser pulses and illumination pulses may be synchronized for a stroboscopic effect. The laser system may also monitor laser electromagnetic radiation that is returned back through the fiber-optic cable.

Abstract: Disclosed herein are systems and methods for compensating for a tilt of an intraocular lens (IOL) and systems and methods for adjusting the IOL. For example, one of the methods can comprise capturing one or more optical coherence tomography (OCT) images of an eye of a subject when the IOL is implanted within the eye of the subject. The method can also comprise generating a fixation target such that the fixation target is visible to the eye of the subject and moving the fixation target until a transverse plane of the IOL is perpendicular or substantially perpendicular to an optical axis of an ophthalmic system. The method can also comprise directing a laser beam generated by a laser of the ophthalmic system at the IOL.

Abstract: In certain embodiments, an ophthalmic laser system for treating a floater in a vitreous of an eye includes a laser device that directs laser pulses towards the floater to yield cavitation bubbles that create a bubble jet to treat the floater. In some examples, the laser device includes a beam multiplexer that splits a laser beam into multiple beams that form the cavitation bubbles that create the bubble jet. In some examples, the laser device directs laser pulses towards the floater according to a pulse pattern that forms the cavitation bubbles that create the bubble jet.

Abstract: In certain embodiments, an ophthalmic surgical system for viewing an eye includes an ophthalmic microscope and a laser device. The ophthalmic microscope receives light reflected or scattered backwards from within the vitreous of the eye in order to provide an image of an object within the vitreous. The ophthalmic microscope includes a slit illumination source (which includes a light source and an optical element), a spectral filter, and oculars. The slit illumination source illuminates the eye with light, where the light source provides the light, and the optical element directs the light into the eye. The spectral filter filters out red spectral components of the light. The oculars receive the light from the eye in order to provide the image of the object. The laser device generates a laser beam to direct towards the object within the eye.

Abstract: In certain embodiments, an ophthalmic laser system comprises a laser source, multi-focal optics, scanners, delivery optics, and a computer. The laser source generates a laser beam of ultrashort laser pulses. The multi-focal optics multiplex the laser beam to yield focus spots in a target along a propagation axis of the laser beam. The scanners direct the laser beam in x, y, and z directions. The delivery optics focus the laser beam within the target to form the focus spots in the target along the propagation axis of the laser beam. The computer instructs the scanners and the delivery optics to direct and to focus the focus spots at the target according to a scan pattern.

Abstract: The devices and methods described herein provide improved methods for accurately identifying and locating the visual axis of the eye and its intersection with the iris plane. In one embodiment, a visual axis identification system includes a fixation light source, a camera, and a processing system. During operation thereof, the patient focuses their gaze onto two or more fixation light spots provided by the fixation light source upon an optical axis thereof, which creates two or more corresponding images on or near to the patient's retina. The patient's head is then rotated relative while the patient continuously maintains their gaze on the fixation light spots. The patient's visual axis may be located by determining the location of the optical axis of the fixation light source relative to the patient's eye when the centers of the multiple images coincide in the patient's view.

Abstract: The disclosure provides a method for correcting higher-order aberrations including providing a laser radiation. The method also includes controlling a location of a beam focal point of the laser radiation by a system of scanners and guiding the beam focal point in such a way that the location of the beam focal point is in a cornea of an eye. The method further includes introducing the laser radiation into the cornea of the eye. The method includes cutting a lenslet, wherein a thickness of the lenslet t(X,Y) satisfies a following equation: t(X,Y)=t0+Δt(X,Y)/(n−1), where Δt(X,Y) represents a higher-order wavefront elevation and t0 represents the thickness of the lenslet having a spherical refractive power of D.

Abstract: Systems and methods are provided for in vivo pre-surgical characterization of lenses, such as cataractous lenses. A method comprises obtaining an electromagnetically-measured value related to the axial thickness of the lens, obtaining an ultrasound-measured value related to the axial thickness of the lens, calculating a relationship value based upon the electromagnetically-measured value and the ultrasound-measured value, and determining a mechanical property value based upon the calculated relationship value. The mechanical property may relate to lens hardness, rigidity, or density, or the amount of energy for a phacoemulsification procedure. A system may comprise an optical interferometer for measuring data to obtain the electromagnetically-measured value and an ultrasound biometer for measuring data to obtain the ultrasound-measured value.

Abstract: Systems and methods are disclosed for selectively allowing or preventing output of laser pulses. In some embodiments, a laser system comprises a shutter and a shutter motor. The shutter motor is configured to move the shutter in an alternating manner between a first position in which output of laser electromagnetic radiation is allowed a second position in which output of laser electromagnetic radiation is prevented.
