  • Patent number: 10716706
    Abstract: A system and method are provided for fragmenting a crystalline lens, to facilitate its removal from the lens bag during an ophthalmic laser surgery. First, a predetermined pattern is used to make Laser Induced Optical Breakdown (LIOB) cuts that section the lens into asymmetrical, operational segments. At least one operational segment is then selected and softened with a plurality of compact LIOB cuts. Once softened, the selected segment is aspirated. The remaining operational segments are then subsequently removed. During a procedure, an imaging unit can monitor movements of the lens bag to ensure proper placement of the LIOB cuts on the lens.

  • Patent number: 10434011
    Abstract: A system and method are provided for removing a natural lens and inserting an Intraocular Lens (IOL) into the lens capsule of an eye. Specifically, this is accomplished by inserting the IOL through an opening on the posterior capsule that is created using a focused laser beam. The system includes a laser unit, a detector for creating images of the interior of the eye, and a computer that controls the cooperative functions of the detector and the laser unit. Based on images of the posterior capsule provided by the detector, the computer is used to control movements of the focal point through tissue of the posterior capsule to perform Laser Induced Optical Breakdown (LIOB) on posterior capsule tissue. The result is a laser capsulotomy that creates an opening through the posterior capsule allowing the natural lens to be removed and the IOL to be implanted.

  • Patent number: 9629750
    Abstract: A comprehensive multi-mode system for performing ophthalmic laser surgery on selected tissue inside an eye includes a laser unit for generating and focusing a laser beam to perform Laser Induced Optical Breakdown (LIOB) at a focal point in selected tissue. Also included is a selector for defining an operational mode according to characteristics of the tissue to be altered by LIOB. In combination, the operational mode specifies value ranges for configuration parameters for a pulsed femtosecond laser beam, establishes a base reference datum in the eye, and identifies a scanning procedure for the focal point of the laser beam to customize the system for a particular surgical procedure. A computer that is connected to the laser unit is responsive to the selector for implementing the operational mode.

  • Patent number: 9603744
    Abstract: Systems and methods are described for stabilizing an eye for an ocular laser procedure while minimizing corneal distortions which can adversely affect a surgical laser beam. For the systems, a patient interface includes a contact element for stabilizing the eye and establishing a conformal interface with the anterior surface of the cornea. More specifically, devices are disclosed which overlay both a central corneal region and a peripheral corneal region. In some embodiments, a first material is used in the contact element to overlay the central corneal region and a second material is used in the contact element to overlay the peripheral corneal region. Typically, the first and second materials differ in terms of hardness and deformability. In another embodiment disclosed herein, a contact element having a viscoelastic material for stabilizing an eye for a laser procedure is described.

  • Patent number: 9398979
    Abstract: An apparatus and method are provided for performing ocular laser surgery using a patient interface having a posterior contact surface that may include surface irregularities that were generated during manufacturing of the patient interface. A beam delivery system having a focusing lens, scanning subsystem and adaptive optic (e.g. deformable mirror) is provided for guiding the surgical laser beam through the patient interface and to a desired focal spot location. An optical detector generates image data representing the posterior patient interface surface which is then processed by a computer system to identify surface irregularities by comparing the image data to a reference surface or axis. In particular, a surface irregularity can be identified as having a z-axis component; a tilt component and a surface profile component. Each irregularity component can be compensated separately by sending an adjustment signal to one of the beam delivery system components.

  • Publication number: 20140276670
    Abstract: A system and method are provided for establishing precise locations for a focal point of a laser beam within a predetermined scanning range during ophthalmic laser surgery. An important aspect of the present invention is the use of a tolerance for deviation of the laser beam's focal point from the laser beam path. The purpose of the tolerance is to ensure that the surgical procedure is effective and that collateral damage to non-targeted tissue does not occur. The present invention accounts for deviations caused by various factors during a procedure. A computer is provided to ensure that the cumulative effect of all deviations maintains the focal point within the tolerance.

  • Publication number: 20140257257
    Abstract: A system and its method for treating targeted tissue in the vitreous cavity of an eye include a laser unit for generating a laser beam and a detector for creating an image of the targeted tissue. The system also includes a computer which defines a focal spot path for emulsifying the targeted tissue. A comparator that is connected with the computer then controls the laser unit to move the focal spot of the laser beam. This focal spot movement is accomplished to treat the targeted tissue, while minimizing deviations of the focal spot from the defined focal spot path.

  • Patent number: 8807752
    Abstract: A methodology is provided for correcting the placement of a laser beam's focal point. Specifically, this correction is done to compensate for displacements of the focal point that may be caused when implant material (e.g. an Intraocular Lens (IOL)) is positioned on the optical path of the laser beam. The methodology of the present invention then determines a deviation of the laser beam's refracted target position (uncompensated) from its intended target position. A calculation of the deviation includes considerations of the laser beam's wavelength and refractive/diffractive characteristics introduced by the implant material. This deviation is then added to the refracted target position to make the refracted target position coincide with the intended target position of the focal point. The laser beam will then focus to its intended target position.

  • Publication number: 20140135752
    Abstract: A system and method are provided for fragmenting a crystalline lens inside an operational volume in the lens. A reference axis that is based on the crystalline lens is established, and various pluralities of parallel planes are defined relative to the reference axis. A pulsed laser beam is then used to cut tissue in selected planes, to thereby fragment the lens by performing Laser Induced Optical Breakdown (LIOB) on the tissue. In accordance with the present invention each plurality of parallel planes is characterized by a particular inclination angle “?” relative to the reference axis, a particular azimuthal angle “?” relative to the reference axis, and an intersection angle “?” relative to each other.

  • Publication number: 20130103010
    Abstract: A system and method for performing Laser Induced Optical Breakdown (LIOB) on a target tissue includes a detector for imaging the interface surface between the target tissue and a base tissue. Also included is a laser unit for generating a laser beam, and for focusing the laser beam to a focal point. A computer is provided for controlling movement of the focal point. Specifically, this control is accomplished to maintain the focal point in the target tissue, but beyond a predetermined distance from the interface surface. For the present invention, the predetermined distance is established by considerations of laser beam geometry, which are applied in the context of images that are created of the interface surface.
