摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： According to certain embodiments, an ophthalmic surgical system for treating presbyopia comprises controllable components and a computer. The controllable components comprise a light source that generates a light beam and a scanner that directs a focal point of the light beam. The computer determines an ablation profile to remove tissue from a central region and a peripheral region of a cornea of a first eye of a pair of eyes. The ablation profile is designed to remove tissue from the central region to yield a protrusion to provide for near-vision, and to remove tissue from the peripheral region to correct to emmetropia.

摘要： In certain embodiments, an ophthalmic surgical system for creating a lenticule in the cornea of an eye comprises controllable components (including a laser source and a scanner) and a computer. The laser source generates a laser beam, and the scanner directs the focal point of the laser beam. The computer determines a lenticule design for the lenticule having a posterior side and an anterior side. Either the posterior side or the anterior side has a central portion and a peripheral portion. The lenticule design is formed using a major lenslet and a minor lenslet, where the major lenslet is designed to correct to emmetropia. The lenticule design is formed by subtracting the minor lenslet from the major lenslet, where the subtraction of the minor lenslet yields the central portion. The computer instructs one or more of the controllable components to create the lenticule.

摘要： A laser surgical system comprises a laser source, scanners, delivery optics, and a computer. The laser source generates a beam of femtosecond laser pulses. The scanners direct focus spots of the beam towards points of a cornea. The delivery optics focuses the focus spots at the points of the cornea. The computer creates an incision in the cornea by instructing the optics and scanners to: direct and focus the focus spots from a posterior corneal surface, through a convex curve and a concave curve, to an anterior corneal surface to form an S-curve incision with a posterior end and an anterior end. The S-curve incision has a substantially non-planar rectangular shape with a longer side that extends from the posterior end to the anterior end and defines a longer direction. A cross-section of the incision in the longer direction exhibits the convex curve and the concave curve.

摘要： 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 to represents the thickness of the lenslet having a spherical refractive power of D.
