  • Patent number: 7763032
    Abstract: An improved cutter assembly is used to form an aperture in a lens capsule of an eye. The cutter assembly is resiliently deflectable between a contracted condition and an expanded condition. When the cutter assembly is in the contracted condition, it is moved through an opening in the eye into alignment with an anterior portion of lens capsule of the eye. The cutter assembly is then operated to the expanded condition and moved against the anterior portion of the lens capsule under the influence of fluid pressure. To move the cutter assembly against the anterior portion of the lens capsule, a seal engages an anterior portion of the lens capsule and a conduit connected with the cutter assembly is connected in fluid communication with a source of low pressure (vacuum).

    Abstract: A reduction of eye trauma is achieved during opthalmolic surgery branch for implanting the intraocular refractive lens to the anterior chamber of the eye. The pupil is extended by mydriatic compounds and after anesthesia the cornea cut is made (clear cornea—3 mm). Thereafter, the anterior chamber of the eye is filled with viscoelastic compound with low molecular weight and then the refractive lens is implanted with the help of said cannula, the working face of the cannula at the middle between the lens edge and the border of the optic area, with the edge bent on the cannula face. The end by the top of the bending the refractive lens is introduced into the cornea cut and set in the posterior chamber of the eye. Thereafter, vacuum is removed and the cannula is detached from the refractive lens, and taken off the anterior chamber of the eye by the reverse movement. The refractive lens cannula is made as a tube with round or oval cross-section with inner diameter 0.5-2.5 mm and wall thickness not less than 0.

  • Publication number: 20100049176
    Abstract: A device and method of use thereof for incrementally adjusting the size and/or shape of a particular body part is provided. The device comprises first and second layers each formed of a synthetic resin. The first layer is formed of a heat-shrinkable material having a low melting point while the second layer has a melting point much higher than the first layer. Upon being subjected to energy, the first layer will shrink or contract causing the second layer, and thus the overall device, to bend in the direction of contraction. In use, the device is inserted into the particular body part after which energy is applied to the device so as to cause the body to expand, move, reshape, etc. The invention is particularly useful for treatment of accommodative disorders of the eye by positioning one or more of the devices within the eye sclera or attached to the sclera around the limbus so that the sclera and ciliary body are expanded away from the crystalline lens upon being of the device.

  • Publication number: 20090312767
    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.
