  • Publication number: 20230225857
    Abstract: An intraocular lens (IOL) injector cartridge having one or more modifications from conventional designs which reduce stress and strain in the optic of the IOL during passage through the cartridge. One change includes adding axially-oriented ribs in a funnel portion of the cartridge to enable the cartridge wall to flex outward during passage of the IOL, which is compressed to a great degree in the cartridge lumen. Another modification involves providing a longitudinal step along a segment of the inner lumen which biases one free edge of the optic to tuck or dive under the other free edge and encourage spiral folding as the IOL progresses along the gradually narrowing lumen. The third option is modifying the shape of the lumen within the extreme distal end of the cartridge where the lumen is smallest so that it is neither circular nor oval. Each or all of these modifications may be incorporated into a single cartridge.

  • Patent number: 10907429
    Abstract: A tubular includes an outer surface and an inner surface defining a passage. A plug is arranged in the tubular blocking the passage. The plug is formed from a disintegrating on demand (DOD) material. An ignition device is coupled to the plug. An excitation mechanism is selectively operatively associated with the ignition device. The excitation mechanism selectively activates the ignition device to break apart the plug.

  • Patent number: 10537683
    Abstract: A finger grip for receiving and retaining a syringe body of an injection syringe. The finger grip is easily pressed directly onto the syringe and employs a centering feature and a pair of one way, flexible latches that allow easy attachment to a syringe body yet ensures retention during normal and abnormal use. If a high horizontal component force is applied during normal or abnormal use, the finger grip will not become disconnected in an uncontrolled fashion from the syringe body, which might cause injury and/or damage to a patient being injected. The flexible latches may prevent detachment of the finger grip from the syringe below separation force of about 25 lbs.

  • Patent number: 10350061
    Abstract: Accordingly, embodiments of the present invention provide an IOL insertion device that facilitates the injection of the IOL in a controlled manner. The insertion device includes a front modular portion and an injector. The modular portion may be preloaded with an IOL and coupled with the injector. The injector includes a distal portion, a body, and a plunger. The distal portion includes a front seal which has a longitudinal bore at the center, through which a distal portion of the plunger passes. The plunger tip is tapered. The plunger also includes a sealing element situated between its distal portion and its proximal portion. The sealing element includes a small aperture through which a fluid, such as a viscoelastic or a balanced salt solution (“BSS”) and the like, may pass toward the proximal end of the body when the plunger advances distally. As the fluid passes through the small aperture on the sealing element on the plunger, a constant speed and force is maintained as the IOL is ejected into the eye.

  • Patent number: 9788939
    Abstract: A rear-loaded injector cartridge for an intraocular lens (IOL) having a proximal opening that provides a haptic slot. The haptic slot receives a leading haptic of an IOL loaded therein, and temporarily retains the leading haptic while the optic of the IOL is inserted into a holding area of the cartridge. As the optic passes by, the leading haptic folds over the top of the optic, on its anterior side. The length of the haptic retention slot is sufficient to maintain the leading haptic in its anteriorly folded position while the IOL remains in holding area, typically while the cartridge is mated with a handpiece of the injector. The cartridge also has a rear or proximal cut out which advantageously keys with a similarly-sized rail on the handpiece so that the cartridge cannot be inserted in the wrong way.

  • Patent number: 9713525
    Abstract: An intraocular lens for reducing aberrant optical effects includes a substantially oval, elliptical, or rectangular optic with an anterior surface, a posterior surface and a peripheral region/zone disposed about a central optical axis and a plurality of haptics coupled to the optic. The peripheral region/zone has an inflection region/transition area that is inclined with respect to the anterior surface at an angle between about 40 degrees and 120 degrees with respect to the optical axis. The thickness at the edge of the IOL is less than or about 0.03 mm.
