    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.

The vision correction arrangement may be embodied as an intraocular lens implant, or an extraocular device such as spectacles. The intraocular lens implant comprises a fixed lens element (11) and a movable lens (12) element sensitive to the orientation of the eye, so that the optical power of the intraocular lens implant is increased when the user looks downward, and returns to a reduced optical power condition when the user's eye returns to a horizontal gaze. The fixed lens element may have a convex rear surface and a concave front surface, and the second lens element may be pivotally mounted in front of the first lens element, so that downward inclination of the eye causes the second lens element to swing away from the fixed lens element.

    Abstract: Prosthesis delivery devices and methods are provided that enable precise control of prosthesis position during deployment. The catheter for delivering a prosthesis to a treatment site in a body lumen typically carries one or more self-expanding tubular prostheses within a sheath. A radially expandable control member is positionable within the prostheses and has an expanded shape which engages an inner surface of the prostheses to urge the prostheses outwardly against the sheath. The radially expandable control member therefore controls axial position of the prostheses during deployment. Thus one or more prostheses may be deployed at a treatment site precisely. When multiple prostheses are deployed, excessive spacing or overlap between adjacent prostheses is minimized. The prostheses of the present invention are often deployed in stenotic lesions in peripheral arteries as well as coronary arteries and other body lumens.

  • Patent number: 8308799
    Abstract: An intraocular lens (IOL) injection device is modularized to enable cleaning of internal components after surgery. The device includes first and second housing modules. These modules collectively define a passageway along which an injector rod moves between a retracted position and an extended position. The first module is further configured to accommodate a lens cartridge module. The cartridge module has disposed therein an IOL, in alignment with the passageway. Thus as the rod moves from the retracted position to the extended position, a front portion of the rod that is substantially surrounded by the first module in the retracted position moves into the cartridge module and displaces the IOL. This causes the front portion of the rod to accumulate on it viscoelastic substances. The first module, though, is configured to detach from the second module, to thereby expose the front portion of the rod in the retracted position for cleaning.

The stiffness is selected such that after implantation the elongate member deforms eye tissue surrounding the suprachoroidal space forming a tented volume.

  • Publication number: 20120221102
    Abstract: An intraocular lens insertion device having a novel configuration, capable of more accurately arranging front and back surfaces of an intraocular lens in a proper direction. The intraocular lens insertion device is adapted in such a manner that the intraocular lens is set on a stage in a state placed flat with a pair of haptics extended facing front and back sides in a movement direction by a plunger. Also, an interfering acting part is provided to an insertion tube part, and the interfering acting part interferes with the haptic, which is extended facing the front side in the movement direction of the intraocular lens moved by the plunger, to apply on the haptic an external force toward the back side in the movement direction. Thus, the interfering acting part curves and deforms the haptic to a side approaching an optical portion.

  • Patent number: 8246631
    Abstract: A plunger for an IOL injector device includes a shaft with a distal tip and a compressible sleeve positioned about the shaft with the tip extending forwardly of the sleeve. In a first stage of IOL advancement through the injector device, the plunger tip engages and pushes the IOL through a first section of the injector body. In a second stage of IOL advancement, the sleeve enters the narrowing section of the injector body toward the open tip thereof with the IOL and sleeve both undergoing compression. The sleeve compresses and lengthens in a forward direction ultimately enveloping the plunger distal tip. Viscoelastic applied inside the injector accumulates between the leading edge of the compressed sleeve and the compressed IOL thereby creating hydraulic pressure which pushes the compressed IOL through the remainder of the injector body and out the open distal tip thereof.

  • Patent number: 8231643
    Abstract: An apparatus and method for accurately making a limbal relaxing incision. An example universal limbal relaxing guide (ULRIG) includes an inner rotating ring, a measurement gauge, a base unit and bumpers. The inner rotating ring and measurement gauge rotate concentrically relative to the base unit. The inner ring guides a keratome along an arc of constant radius. The measurement gauge enables the user to select the length of the arc and the bumpers prevent the keratome from overshooting the desired incision length. Because the thin degree ring rotates relative to the base unit, the example ULRIG can be used with more than one style of keratome. Multiple marks on a pointing bumper enable the user to adjust the resultant incision length for the cornea size of an individual patient.

  • Patent number: 8142498
    Abstract: Disclosed is an injector which comprises an injector housing having a longitudinal axis and an injection probe disposed along the longitudinal axis. The injector further comprises an intraocular lens disposed in the housing. The intraocular lens comprises first and second interconnected viewing elements, and the optical axes of the first and second viewing elements are substantially aligned. The optical axes are substantially orthogonal to the longitudinal axis of the housing. The injector further comprises a lens carrier which engages one of the viewing elements. The viewing elements are moveable in response to longitudinal movement of the lens carrier relative to the injector housing. The longitudinal movement causes both (i) the optical axes to be displaced relative to each other and (ii) the viewing elements to be disposed substantially on the longitudinal axis of the injector housing.

  • Patent number: 8080017
    Abstract: An intraocular lens insertion tool with a tool body for accommodating an intraocular lens and adapted to insert into an eye the intraocular lens through displacement of the lens in an axial forward direction by a plunging member, and to push out the lens through an insertion tube section disposed at an axial distal end of the tool body. The insertion tube section has an inclined orifice that opens on diagonal to the center axis of the insertion tube section. The plunger member has a sliding part that during displacement thereof in a direction of plunging into the tool body will slide against the tool body. A resistance graduating mechanism is provided for gradually increasing operation resistance of the plunger member by gradually increasing contact force on the sliding part as the lens gradually emerges from the inclined orifice through plunging of the plunger member into the tool body.

  • Patent number: 8062360
    Abstract: An injector and method for injecting a dual optic AIOL into an eye wherein the AIOL is loaded into the injector in an initially loaded condition with the first and second optics in generally coaxial alignment. A lens moving element is provided and operable to move the first optic toward the proximal end of the main body whereupon the first optic becomes located proximally of the second optic. A stop may be provided to prevent the second optic from moving proximally with the first optic. Displacing the optics to a non-coaxial position reduces the cross-sectional area of the AIOL which allows the AIOL to non-destructively compress to the size of the opening of the injector tip which may be as small as about 2.8 mm or less, for example.
