  • Patent number: 8702794
    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.

  • Publication number: 20140005781
    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.

  • Patent number: 8357196
    Abstract: An intraocular lens for providing vision to an animal or human subject has anterior and posterior sides. The lens includes an optic body, one or more haptics, and one or more marks. Each mark has four or more features disposed along an imaginary line when viewed from the anterior side and/or the posterior side. The mark(s) may be used as an aid in angularly aligning the lens during use.

  • Publication number: 20050119676
    Abstract: In accordance with the present invention there is provided an applier for a surgical device and method that provides automated ejection of the device and gives the surgeon use of the applier with one operative control. The applier includes a handle, a tube movable relative to the handle, and an ejector shaft driven by a force element for ejecting the device. It may include a cap called a bullet nose or probe tip. The cap may have a tapered distal surface to ease entry into small otomies in tissue. Using a button or knob to move the tube automatically triggers the ejector shaft to eject the device when the tube is in the correct position.
