Abstract: Systems and methods are disclosed for flexibly controlling laser pulses being output from a laser system. An example surgical system comprises a laser, an optical switching device, and a laser pulse controller. Optical switching control signals communicated by the laser pulse controller control the length of a pulse picking cycle and the number of laser pulses in each pulse picking cycle to be output from the laser system. The number of laser pulses in each pulse picking cycle to be output from the laser system may be adjustable in a range that includes more than 50% of the laser pulses in each pulse picking cycle.

Abstract: In certain embodiments, an ophthalmic surgical system for ablating tissue of an eye comprises controllable components (such as a light source and a scanner), optical elements, and a computer. The light source generates a light beam comprising pulses, where a propagation direction of the light beam defines a z-axis. The scanner directs a focal point of the light beam in an xy-plane orthogonal to the z-axis. The optical elements shape and focus the focal point of the light beam at a treatment region of the eye. The computer instructs one or more of the controllable components to generate the light beam comprising the pulses, where each pulse has a fluence greater than 1 J/cm2. An optical element of the optical elements focuses the focal point of the light beam with a spot size of less than 0.4 mm at the treatment region according to a focal spot pattern.

Abstract: Disclosed herein is a method of performing ophthalmic surgery. The surgery includes positioning a patient interface relative to a patient's eye with the patient interface at least partially defining an interface chamber with the patient's eye. The interface chamber is filled with an immersion fluid. A fluid in an anterior chamber of the patient's eye is replaced with the immersion fluid, wherein the immersion fluid matches the refractive index of the cornea. A laser system is positioned relative to the patient interface. The laser system includes a laser source configured to generate a femtosecond laser beam and an optical delivery and scanner system in communication with the laser source to direct 3D scanned and focused laser beams through the patient interface and into the patient's eye.

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: Systems and methods are disclosed for dynamically controlling laser pulses being output from a laser system. An example surgical system comprises a laser, an optical switching device, an adjustable input device such as a foot pedal, and a laser pulse controller. An operator actuates the adjustable input device over an operating range to control dynamically the laser pulses being output from the laser system. In one mode, the adjustable input device may dynamically control output laser energy. In another mode, the adjustable input device may dynamically control selection of laser pulses to be output from the system.

Abstract: 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.

Abstract: 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.

Abstract: Systems and methods for assisting in the removal of a cataract from an eye can include obtaining pre-operative data for the eye, the pre-operative data including imaging data associated with the lens of the eye, determining a lens density map based on the imaging data associated with the lens, and generating laser fragmentation patterns for a laser fragmentation procedure based on the lens density map.

Abstract: 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.
