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: 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.

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 to 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: An ophthalmic device includes at least one ophthalmic lens and at least one diffractive structure for the at least one ophthalmic lens. The ophthalmic lens(es) have at least one base focal length and a base power for a first wavelength of visible light. The diffractive structure(s) have a chromatic aberration such that the diffractive structure(s) have a first power for the first wavelength of visible light and a second power for a second wavelength of visible light. A difference between the first power and the second power is at least two diopters.

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: Particular embodiments disclosed herein enable psychophysical evaluation of vitreous floaters. One or more patient stimulus images are projected onto the patient's retina, the patient images including a stationary or mobile fixation target. While the patient stimulus images are displayed, images of the patient's retina are captured, such as using an SLO, and shadow images are derived from the images. The shadow images include representations of shadows cast by floaters. Observer stimulus images are generated from the shadow images and the patient stimulus images and projected onto the retinas of an observer, such as using a virtual reality display device.

Abstract: In certain embodiments, a surgical contact lens system for ophthalmic treatment with a laser beam includes a patient contact lens and a surgical contact lens. The patient contact lens reduces one or more refractive errors of the eye and has a concave surface and a convex surface. The concave surface is to be disposed outwardly from a cornea of an eye. The surgical contact lens has an eye end to be disposed outwardly from the convex surface of the patient contact lens. The surgical contact lens includes a frame and an optical component coupled to the frame. The patient contact lens reduces pressure from the surgical contact lens to reduce corneal folding of a posterior surface of the cornea. The optical component of the surgical contact lens and the patient contact lens transmit the laser beam to treat the eye.
