VARYING A NUMERICAL APERTURE OF A LASER DURING LENS FRAGMENTATION IN CATARACT SURGERY

Some embodiments disclosed here provide for a method fragmenting a cataractous lens of a patient's eye using an ultra-short pulsed laser. The method can include determining, within a lens of a patient's eye, a high NA zone where a cone angle of a laser beam with a high numerical aperture is not shadowed by the iris, and a low NA zone radially closer to the iris where the cone angle of the laser beam with a low numerical aperture is not shadowed by the iris. Laser lens fragmentation is accomplished by delivering the laser beam with the high numerical aperture to the high NA zone, and the laser beam with the low numerical aperture to the low NA zone.

Принадлежит: Strathspey Crown Holdings LLC

A post-operative procedure is disclosed for inducing a Posterior Vitreous Detachment (PVD) after a VitreoRetinal-Interface Syndrome (VRS) treatment. In the post-op procedure, vitreoretinal interface tissue is imaged to determine the extent of PVD that was established by the VRS treatment and Residual Areas of Adhesion (RAA) are identified on the vitreoretinal interface. Once the RAAs are identified, the next step is to allow gas micro-bubbles on the vitreoretinal interface which were generated during the VRS treatment to move, coalesce, and/or loosen tissue at the vitreoretinal interface, and thereby facilitate completion of a PVD. During the bubble coalescing period, ultrasound energy can be applied to bubble/tissue boundaries to accelerate bubble coalescence and/or increase the rate that RAA tissue is loosened at the vitreoretinal interface. After bubble coalescence, tissue at the RAA can be photoaltered using a focused femtosecond laser beam to induce a suitable PVD.

The method including controlling the laser by means of a control device such that it emits pulsed laser pulses in a shot sequence into the cornea. The interfaces are generated by the generation of a plurality of cavitation bubbles generated by photodisruption by means of an interaction of the individual laser pulses with the cornea. A minimum diameter of the volume body orthogonal to an optical axis of the volume body is determined depending on at least one diopter value for the volume body and on a preset thickness of the volume body viewed in a direction of the optical axis. A treatment apparatus, a computer program product and a computer-readable storage medium are also disclosed.

The present invention relates to an ophthalmic treatment apparatus and to a beam control method therefor. The ophthalmic treatment apparatus according to the present invention comprises: a beam generating unit for generating beams having different pulse energies; a bubble sensing unit for sensing whether or not bubbles have been generated, as well as the amount of generated bubbles, on the basis of the pulse energy of the beam generated by the beam generating unit and radiated onto the treatment region of an eyeball; and a control unit for controlling the operation of the beam generating unit such that the pulse energy of the beam generated by the beam generating unit can be adjusted in accordance with the signal from the bubble sensing unit. 1a beam generation unit which generates beams having different types of pulse energy;a bubble detection unit which detects whether a bubble is generated or an amount of bubbles generated by the pulse energy of the beams generated by the beam generation unit and radiated to a treatment region of an eyeball; anda control unit which controls an operation of the beam generation unit based on a signal from the bubble detection unit so that the pulse energy of the beams generated by the beam generation unit is controlled.. An ophthalmic treatment apparatus, comprising: This application is a continuation of U.S. patent application Ser. No. 14/414,696, filed Jan. 13, 2015, now U.S. Pat. No. 10,080,683 issued Sep. 25, 2018, which is a U.S. National Stage Application of PCT/KR2013/006331 filed Jul. 15, 2013, which claims priority to Korean Patent Application 10-2012-0076779 filed Jul. 13, 2012, which are hereby incorporated by reference in their entirety.The present invention relates to an ophthalmic treatment apparatus and a method of controlling, by the ophthalmic treatment apparatus, beams and, more particularly, to an ophthalmic treatment apparatus for measuring pulse energy of a beam for treatment that is radiated to the treatment ...

Method and system for modifying eye tissue and intraocular lenses

Номер: US20190021904A1

A system for ophthalmic surgery includes a laser source configured to deliver an ultraviolet laser beam comprising laser pulses having a wavelength between 320 nm and 370 nm to photodecompose one or more intraocular targets within the eye with chromophore absorbance. The pulse energy, the pulse duration, and the focal spot are such that an irradiance at the focal spot is sufficient to photodecompose the one or more intraocular targets without exceeding a threshold of formation of a plasma and an associated cavitation event. An optical system operatively coupled to the laser source and configured to focus the ultraviolet laser beam to a focal spot and direct the focal spot in a pattern into the one or more intraocular targets. The optical system focuses the laser beam at a numerical aperture that provides for the focal spot to be scanned over a scan range of 6 mm to 10 mm.

A method for producing a cut surface in a transparent material using optical radiation. A laser device separates the material using optical radiation and includes an optical unit focussing the radiation along an optical axis into an image field defining an image-field size. A focal position is adjusted transversely along the axis, producing a cut surface extending substantially parallel to the axis and, in projection along the axis, is a curve having a maximum extent. The focus is displaced by adjustment of the focal position along a trajectory curve lying in the cut surface. The cut surface has a maximum extent which is greater than the image-field size. The focal position is moved transverse to the axis along the curve. The image field is displaced transversely, and the focal position is adjusted in an oscillating fashion along the axis on the curve between an upper and lower axial focus position. 1. A treatment apparatus for producing a cut in a transparent material , the apparatus comprising:a laser device which is adapted to generate a cut within the transparent material using optical radiation, the laser devicea control device which is connected to the laser device and controls the laser device such that a focus adjustment device moves the position of the focus of the optical radiation in the material along a path, wherein the control device controls the laser device such that the cut has, in projection along an optical axis, a form of a curve,2. A method for producing control data for producing a cut in a transparent material , whereinthe control data are designed for a laser device comprising: 'a focus adjustment device for moving a position of the focus,', 'optics configured to focus the optical radiation along an optical axis into a focus situated in the material and which have in the material an image field in which the focus lies and which has an image field size, and'}wherein the control data are produced to comprise data for the focus adjustment device ...
