Lenses, systems and methods for providing binocular customized treatments to correct presbyopia
An apparatus, such as lenses, a system and a method for providing custom ocular aberrations that provide higher visual acuity. The apparatus, system and method include inducing rotationally symmetric aberrations along with an add power in one eye and inducing non-rotationally symmetric aberrations along with an add power in the other eye to provide improved visual acuity at an intermediate distance.
Additive manufacturing inside the human eye
Additive manufacturing techniques are used to form an artificial intra-ocular lens (IOL) directly inside the human eye. Small openings are formed in the cornea and lens capsule of the eye, and the crystalline lens is broken up and removed through the openings; then, a material is injected into the lens capsule through the openings, and the focal spot of a pulse laser beam is scanned in a defined pattern in the lens capsule, to transform the material in the vicinity of the lase focal spot to form the IOL in a layer-by-layer manner. In one embodiment, stereolithography techniques are used where a pulse UV laser source is used to photosolidify a photopolymer resin. The liquefied resin is injected into the eye through the openings, after which only part of the resin, having the shape of the desired IOL, is selectively cured with the UV laser beam, via progressive layer formation.
CREATING CUTS IN A TRANSPARENT MATERIAL USING OPTICAL RADIATION
A method for creating cuts in a transparent material using optical radiation, the optical radiation being focused onto the material in a focal point and the focal point being shifted along a curve: A simple or double harmonic curve is used when seen at a right angle to a main direction of incidence of the radiation and preferably successively traveled curves do not lie on top of each other.
Astigmatism correction
A therapeutic method can include receiving an initial astigmatism condition of an eye; receiving a target final astigmatism condition of the eye; generating, based on the initial and target final astigmatism conditions, an eye incision pattern by iterating through a plurality of potential corrective combinations; and cutting the eye based on the eye incision pattern. Each of the potential corrective combinations can be defined by one or more of: an intraocular lens selected from a plurality of intraocular lens options, an access incision selected from a plurality of access incision options, and an arcuate incision selected from a plurality of arcuate incision options.
Apparatus for the treatment of cataract
An apparatus to treat a cataract where the cataractous lens is pierced and the resulting opening is mechanically maintained using a lens system device such as a cylindrical lens, tubular lens, pinhole device, a stent or similar small diameter device, or where the device itself is the lens. The resulting passageway for visible light created in the cataractous lens allows light to better reach the retina, thus improving vision. This lens system device that can be placed into an in situ cataract provides for a much simpler surgical technique and reduces related pre and post operative procedures and potential complications. Intraocular lenses may also be used in concert with this invention. The apparatus and related methods can be applied to humans as well as animals.
LASER SURGICAL SYSTEM FOR S-CURVE INCISION
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.
OPHTHALMIC LASER SYSTEMS WITH Z-DIRECTION MULTI-FOCAL OPTICS
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.
Positioning device, light processor having such a positioning device, and method for laser eye surgery using such a light processor
The present disclosure relates to a positioning device for positioning an object in a positioning plane. To minimize the position error (contouring error) in a continuous orbital travel in contrast to two linear adjusters (X and Y) arranged at a right angle to each other, the positioning device includes two rotation drives having different diameters and an object receiver for receiving the object. The object receiver is coupled to a first of the two rotation drives, which in turn is coupled to the second of the two rotating drives so that the object receiver is rotatable about the axes of rotation (A2, A3) of both rotation drives that are offset in parallel, and is thereby adjustable in the positioning plane. A light processor having such a positioning device, and a method for laser eye surgery using such a light processor are also disclosed.
PATIENT INTERFACE DEVICES AND METHODS AND SYSTEMS FOR COMBINED SONIC AND LASER APPLICATIONS
A patient interface device (PID) for contacting the surface of the eye and having a meniscus inverter. A pin, clip and ridge configuration for holding a window and maintaining an open reservoir of BSS in a PID. A PID for integrated systems and methods for performing laser and phacoemulsification operations. A PID for a reconfigurable system for performing a laser procedure in a laser configuration, and then being reconfigured into a phaco configuration, to perform a phacoemulsification, and then being reconfigured back to the laser configuration.
Scleral translocation elasto-modulation methods and apparatus
A laser delivery system is configured to delivery light energy to soften and realign the tissue of the eye in order to increase accommodation and treat glaucoma. The laser system can be configured to increase a circumlental space of the eye and increase movement of a posterior vitreous zonule in order to increase accommodation. The light energy may comprise wavelengths strongly absorbed by collagen of the sclera. In many embodiments a heat sink is provided to couple to the conjunctiva and the heat sink comprises a material transmissive to the light energy absorbed by collagen, for example Zinc Selenide. The heat sink can be chilled to inhibit damage to the conjunctiva of the eye. In many embodiments, one or more layers of the epithelium of the eye remain substantially intact above the zone where the eye has been treated when the heat sink has been removed.
