    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: 20140135749
    Abstract: A system and method for performing a femto-fragmentation procedure on tissue in the crystalline lens of an eye requires that a laser beam be directed and focused to a focal point in the crystalline lens of the eye. The focal point is then guided, relative to an axis defined by the eye, to create a segment cluster by causing Laser Induced Optical Breakdown (LIOB) of tissue in the crystalline lens. The resultant segment cluster includes a plurality of contiguous, elongated segments in the crystalline lens that are individually tapered from an anterior end-area to a posterior end-area. Specifically, this is done to facilitate the removal of individual segments from the segment cluster in the crystalline lens.

    Abstract: A system and method are disclosed for using a laser unit to treat a crystalline lens (or lens capsule) to compensate for any tilt angle “?” there may be between a lens axis and an operational axis of the laser unit (i.e. “z” axis). To begin, a contiguous sequence of procedure paths that collectively define the boundary surface of a lens volume are identified, with each procedure path inclined by the tilt angle “?”. A slice occurs in an x-y plane that is on the boundary surface of the volume of lens and includes portions of several procedure paths. The slices are projected into the x-y plane where they are sequenced for use as trace paths for the laser unit. The trace paths are used to guide a laser beam to perform LIOB along the slice for the different values of “z” to incise the boundary surface.

    Abstract: A method of treating glaucoma in an eye by managing fluid flow past an implanted shunt having an elastomeric plate and a non-valved elastomeric drainage tube. The plate is positioned over a sclera of the eye with an outflow end of the elastomeric drainage tube open to an outer face of the plate. An inflow end of the drainage tube tunnels through the sclera to the anterior chamber of the eye. The plate may have regions of greater propensity for cell adhesion alternating with regions of lesser cell adhesion. For example, regions of texturing around the plate or drainage tube may be provided to control the size of a bleb that forms over the implant. The effective surface area of the plate may be balanced against a number of fenestrations. The drainage tube has a reduced profile and may be shaped with a non-circular external cross-section to reduce its height.

  • Patent number: 8562596
    Abstract: A laser-assisted method for fully or partially separating tissue such as collagen-containing tissue is provided. In one embodiment, the method pertains to a capsolurorhexis whereby the laser-assisted method is applied to the lens capsule. A light-absorbing agent is added into or onto the tissue. A light beam with a wavelength capable of being absorbed by the light absorbing agent is then directed at the tissue to cause a thermal effect at the tissue following a predetermined closed curve with the goal to avoid irregularity or potential tears in the resulting rim of the tissue.

  • Publication number: 20130237971
    Abstract: A surgical laser system can include a laser engine to generate a laser beam of laser pulses; a scanning delivery system to direct the laser beam to a target region and to scan the laser beam along a scan-pattern in the target region; and a spatio-temporal modulator to perform a space- and time dependent modulation of the laser beam. The spatio-temporal modulation of the phases or amplitudes of the beam components can reduce or even eliminate uncut regions in the target region, caused by the destructive interference of the beam components brought about by a wrinkling of a portion of the target or by other beam distorting factors.

  • Patent number: 8518027
    Abstract: A phototherapy device includes a light source; a light emanation block; and a heat exchanger for the dissipation of heat from one or more heat loads associated with the device. Heat may be transferred via the heat exchanger from the light source independently of the dissipation of heat from one or more of the other device heat loads. Substantially thermally isolated heat transfer regions may be provided, and such regions may be maintained at different operating temperatures, to control the transfer of heat in conjunction with a phototherapy method and to promote efficient and enhanced device operation and performance.

  • Publication number: 20130218145
    Abstract: The invention provides a device for delivering electromagnetic radiation to a limbal area of an eye that transforms one or more beams of electromagnetic radiation that are incident on a first side into one or more emitted beams of the electromagnetic radiation where the one or more beams are arrayed in a cylindrical array, an array of one or more beams each beam having a cross sectional shape of a circular arc or an array comprising a beam having an annular cross section. The invention also provides a system for delivering electromagnetic radiation to the limbal area of an eye that includes one or more devices of the invention and a source of electromagnetic radiation. The system may be used in the treatment of glaucoma.

    Abstract: System and method for making incisions in eye tissue at different depths. The system and method focuses light, possibly in a pattern, at various focal points which are at various depths within the eye tissue. A segmented lens can be used to create multiple focal points simultaneously. Optimal incisions can be achieved by sequentially or simultaneously focusing lights at different depths, creating an expanded column of plasma, and creating a beam with an elongated waist.

  • Publication number: 20130190737
    Abstract: Embodiments apply light energy in medical treatments. To enhance or control the effect of the light energy, embodiments apply the light energy after tissue has been treated, e.g., with a photosensitizing agent. For example, embodiments may treat target tissue with riboflavin before exposure to ultraviolet light. For example, a system for cataract surgery includes a removal system configured to remove a first lens from an eye, wherein a capsular bag remains in the eye after removal of the first lens. The system includes an application system configured to treat lenticular epithelial cells in the capsular bag with the photosensitizing agent. The system includes a delivery system with a light source and an optical device. The optical device delivers light to the treated lenticular epithelial cells. Energy from the light destroys the lenticular epithelial cells in the capsular bag to reduce the growth of epithelial cells that cause posterior capsule opacification.
