  • Publication number: 20110135626
    Abstract: A high-intensity pulsed-electrical-field (HIPEF) apparatus chemically induces lysis of ocular tissue within a localized portion of an eye. Instead of broadly applying a lysis affecting solution (e.g., plasmin) to the eye, the apparatus delivers solution to only a portion of the eye. The apparatus then alters the effectiveness of at least some of the solution delivered by applying a HIPEF to that solution. In some embodiments, for example, the apparatus delivers a solution that does not substantially affect lysis of ocular tissue and then enhances the solution's effectiveness by applying a HIPEF. As the apparatus applies the HIPEF with high precision, the HIPEF only enhances the effectiveness of the solution within select and localized portions of the eye. The apparatus is especially advantageous for vitreoretinal surgery, whereby the apparatus may selectively induce lysis of vitreous tissue within a localized portion of the vitreous cavity, without significantly affecting adjacent retinal tissue.

  • Publication number: 20110135579
    Abstract: RNA interference is provided for inhibition of tumor necrosis factor ? (TNF?) by silencing TNF? cell surface receptor TNF receptor-1 (TNFR1) mRNA expression, or by silencing TNF? converting enzyme (TACE/ADAM17) mRNA expression. Silencing such TNF? targets, in particular, is useful for treating patients having a TNF?-related condition or at risk of developing a TNF?-related condition such as the ocular conditions associated with elevated intraocular pressure (IOP), including glaucoma and ocular hypertension.

  • Patent number: 7956341
    Abstract: Embodiments of the present invention provide a system and method for detecting the level of a fluid in a surgical cassette by projecting light from a linear light source into a wall of a cassette. Depending on the amount a light reflected or refracted in the cassette (i.e., due to the cassette material/fluid interface or cassette material/air interface (or other interface)) various portions of a linear sensor array will be more or less illuminated. By examining the illumination of the linear sensor array, the level of fluid in the chamber can be determined.

  • Patent number: 7954945
    Abstract: A system for positioning an eye of a patient, for example, for laser ophthalmic surgery includes a reflectometer adapted to receive as input a reflected beam from an anterior surface of a cornea of an eye of a patient. The interferometer is calibratable to a desired position of the corneal anterior surface. A comparator is in signal communication with the interferometer and is adapted to calculate from the input a difference between an actual position and the desired position of the corneal anterior surface. A device is in signal communication with the comparator for moving the patient a distance in a direction for matching the actual position to the desired position of the corneal anterior surface.

  • Patent number: 7944553
    Abstract: A method and system for measuring an optical property of a multi-focal lens are disclosed. One embodiment of the method comprises: filtering out light transmitted by all but one of a plurality of diffraction orders of the lens to provide an unfiltered light from a single diffraction order; receiving the unfiltered light at a wavefront detector; and analyzing the unfiltered light at the wavefront detector to measure the optical property. The multi-focal lens can be a multi-focal diffractive intra-ocular lens. The measured optical property can be a discontinuity in the lens surface. Filtering can comprise blocking all but the unfiltered light using an aperture operable to let through the unfiltered light from the single diffraction order, and/or blocking all but the unfiltered light using an opaque obstruction operable to let through only a selected amount of light corresponding to the light transmitted by the single diffraction order.

  • Patent number: 7945341
    Abstract: A graphical user interface for use in phacoemulsification surgical systems that allows a user to select different pulse modes by touching portions of the display screen. The user interface includes first and second display elements. One display element includes a representation of the on-time of the pulses, and the other display element includes a representation of the off-time. The representations show how the on-time and off-time change relative to a position of a controller, such as a foot pedal. The representation show a constant time, or that a time increases or decreases as the foot pedal is pressed. To select a pulse mode, a user can scroll through different pulse representations by touching the screen at the display elements. The selected pulse mode can be continuous, pulse, burst and other modes.
