  • Patent number: 10314691
    Abstract: An intra-ocular device includes an electronic lens that can be controlled to control the overall optical power of the device. The device can be installed within a flexible polymeric material shaped to conform to the inside surface of a lens capsule of an eye. Accommodation forces applied to the device and/or polymeric material via the lens capsule can cause a change in the optical power of the device and/or polymeric material. Further, such accommodation forces can be detected by an accommodation sensor of the device and the optical power of the electronic lens can be controlled based on the detected accommodation forces. Operated in this way, the device and polymeric material can restore a degree of accommodation to the eye that is related to existing mechanisms for controlling such accommodation, i.e., forces exerted by the eye via the lens capsule.

  • Patent number: 8858625
    Abstract: An injector (1) for folding and injecting into the eye of a patient a flexible intraocular lens, the injector comprising an assembly of an injection nozzle (202), a lens compartment that holds an unfolded flexible intraocular lens (400) and is in communication with the injection nozzle, an injector body (3) communicating with the lens compartment and a plunger (2) that is inserted in the free end of the injector body, wherein lens compartment and injector body comprise a mechanism whereby the lens is first folded by forces compressing the lens in a non-axial direction in response to an axial movement of the plunger over a first distance and is subsequently expelled from the injector through the injection nozzle in response to an axial movement of the plunger over a second distance.

  • Publication number: 20140277431
    Abstract: System and methods for a corrective eye procedure include at least one application device configured to be positioned at a selected area of an eye (e.g., equatorial sclera, posterior sclera, cornea, etc.). The at least one device includes at least one channel and at least one illumination guide. A cross-linking agent source is coupled to the at least one channel. An illumination source is coupled to the at least one illumination guide. The at least one device delivers the cross-linking agent to the selected area of the eye. The at least one device delivers photo-activating light from the illumination source to the selected area of the eye after the cross-linking agent has been delivered. The photo-activating light includes one or more doses necessary for activating the cross-linking agent and for activating TGF-? isoforms to improve health of extracellular matrices in the selected area of the eye.

  • Patent number: 8808308
    Abstract: An intraocular lens injection device comprises a tubular housing with a plunger longitudinally disposed within the tubular housing. An electric drive system longitudinally translates the plunger so that its tip engages an insertion cartridge to fold and displace an intraocular lens disposed within and to inject the folded lens into the lens capsule of an eye. A control circuit is configured to start translation of the plunger, responsive to user input, to detect at least one fault condition based on a counter-electromotive force produced by the electric motor, and to stop translation of the plunger assembly responsive to the detected fault condition, which may comprise excessive resistance to forward or rearward translation of the plunger or insufficient resistance to forward translation of the plunger.

  • Patent number: 8801634
    Abstract: For use with a surgical tool for making incisions in the sclera of an eye to form a scleral pocket to receive a scleral prosthesis, a system and method is disclosed for determining a position on the sclera for locating the scleral pocket. The system and method determines an optimum location for the scleral pocket. The system and method determines a location on the sclera that represents the intersection of the lens equatorial plane with the external surface of the sclera. The front of the scleral pocket is placed at a location that is four hundred fifty microns posterior to the intersection of the lens equatorial plane with the external surface of the sclera.

  • Patent number: 8801780
    Abstract: The present disclosure is directed to devices, systems, and methods directed to mounting a plunger tip to a plunger of an IOL injection device. A plunger tip wrench that is operable to releasably retain a plunger tip may be coupled to a holder extending from an end of the IOL injection device to align the plunger tip with the plunger of the IOL injection device. In some instances, the IOL injection device may include a motor and use a back electromotive force (EMF) of the motor to detect a position of the plunger as it is extended to engage the plunger tip. The plunger tip may be positioned relative to the plunger such that the plunger will engage the plunger tip within the entire range of a negative error position and a positive error position.

  • Patent number: 8784485
    Abstract: An injector for inserting an intraocular lens into an eye includes a lumen. The lumen can include a terminal portion at a distal end and a proximal portion juxtaposed with the terminal portion. An injector plunger can be disposed within the lumen for generating a driving force on the intraocular lens. The injector can include a lens frictional force that has a first value when the lens is at a first location within the proximal portion and a second value when the lens is at a second location within the terminal portion. The first value can be smaller than the second value. In some embodiments, the lens frictional force increases abruptly from the first value to the second value as the lens approaches the distal end of the lumen.

  • Patent number: 8758433
    Abstract: A system and method for performing an ocular surgical procedure is provided. The design provides an intra-ocular lens (IOL) to an eye through an incision in the eye by assessing IOL insertion conditions, translating said IOL insertion conditions into a desired force range for insertion of the IOL via the incision, controlling a power source to move the IOL to the eye, monitoring conditions, such as force encountered, while controlling the power source. The design employs feedback of the force encountered and selectively alters force applied based on force encountered.
