Abstract: In certain embodiments, an ophthalmic laser system includes a laser device and a computer, where the laser device includes a laser and a phase modulator. The laser device directs a laser beam towards a target in an eye, where an intraocular lens (IOL) is disposed within the eye. The IOL has a phase profile that yields an IOL phase shift of light entering the eye. The laser generates the laser beam. The phase modulator has a phase front that yields a first phase shift of the laser beam that changes to a second phase shift when the laser beam reaches the IOL. The second phase shift is an inverse to the IOL phase shift.

Abstract: In certain embodiments, an ophthalmic laser surgical system for treating a floater in a vitreous of an eye includes a floater detection system, a laser device, and a computer. The floater detection system determines the location of the floater in the vitreous of the eye. The laser device directs a laser beam along a laser beam path towards the floater. The computer accesses a three-dimensional scan pattern for the laser beam that yields a three-dimensional pulse pattern of laser pulses. The three-dimensional pulse pattern has a bubble shield pulse pattern at the posterior side of the three-dimensional pulse pattern. The bubble shield pulse pattern forms a bubble shield that reduces laser radiation exposure at a retina of the eye. The computer instructs the laser device to direct the laser beam towards the floater according to the three-dimensional scan pattern.

Abstract: In certain embodiments, an ophthalmic laser system includes a laser device, an ophthalmic microscope, a z-direction sensor, and a controller. The laser device directs a laser beam towards a target within an eye. The ophthalmic microscope receives light from a focal point within the eye to provide an image of an object at the focal point. The z-direction sensor determines the z-position corresponding to the focal point of the ophthalmic microscope. The controller determines a position Z0, the z-position where the focal point of the ophthalmic microscope is at the retina of the eye; determines a position Z, the z-position where the focal point of the ophthalmic microscope is at the target within the eye; calculates a target-to-retina distance ΔZ according to a difference between the position Z and the position Z0; and calculates a radiant exposure He at the retina according to the target-to-retina distance ΔZ.

Abstract: In certain embodiments, an ophthalmic laser system that performs a laser procedure on an eye includes a laser device, an ophthalmic microscope, a y-direction motor, a user interface device, and a controller. The laser device includes a laser delivery head that directs a laser beam towards a target within the eye. The laser beam defines a z-axis, which defines an xy-plane with a y-axis that defines a y-direction. The ophthalmic microscope receives light from within the eye to provide an image of the eye. The user interface device receives instructions from a user. The controller receives an instruction from the user interface device to move the laser delivery head and the ophthalmic microscope in the y-direction, and instructs the y-direction motor to move the laser delivery head and the ophthalmic microscope in the y-direction in response to the instruction.

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: The present disclosure generally relates to methods and apparatus for accurate identification of the visual axis of the eye. In one embodiment, a visual axis identification system includes a fixation light source, a camera, a processing system, and a multifocal lens. The patient focuses their gaze through the multifocal lens and onto a fixation light beam provided by the fixation light source. The passage of the fixation light beam through the multifocal lens creates two or more images on or near to the patient's retina. The multifocal lens and/or the patient's eye are then moved relative to each other while the patient continuously maintains their gaze on the fixation light beam. The patient's visual axis may be located by determining the location of the optical center of the multifocal trial lens relative to the patient's eye when the centers of the multiple images coincide on the retina.

Abstract: Systems and methods for intraocular lens selection include receiving, by one or more computing devices implementing a prediction engine, pre-operative multi-dimensional images of an eye; extracting, by the prediction engine, pre-operative measurements of the eye based on the pre-operative images; estimating, by the prediction engine using a prediction model based on a machine learning strategy, a post-operative position of an intraocular lens based on the extracted pre-operative measurements; selecting a power of the intraocular lens based on the estimated post-operative position of the intraocular lens; and selecting the intraocular lens based on the selected power. In some embodiments, the systems and methods further include receiving post-operative multi-dimensional images of the eye after implantation of the selected intraocular lens, extracting post-operative measurements of the eye, and updating the prediction model based on the pre-operative measurements and the post-operative measurements.

Abstract: In certain embodiments, an ophthalmic surgical laser system for imaging and treating an eye floater includes an SLO subsystem, a treatment laser subsystem, a scanner, optical elements, and a computer. The SLO subsystem provides an SLO laser beam with an SLO focal point, and the treatment laser subsystem provides a treatment laser beam with a treatment focal point that spatially coincides with the SLO focal point. The scanner scans the SLO laser beam across a scan region and directs the treatment laser beam to the xy-location of the scan region. The optical elements aim the SLO laser beam and the treatment laser beam at substantially the same point of the scan region. The computer receives an SLO image of the floater, determines an xy-location of the floater, and instructs the treatment laser subsystem to direct the treatment laser beam towards the xy-location and the z-scan location of the floater.

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.
