  • Patent number: 10271624
    Abstract: A system for releasing a contained volume of gas. The system has a base with a pressure-release vent positioned within a flex region and a seal to disengagably seal the pressure-release vent. The seal has a gas vent path that extends from the pressure-release vent. The contained volume of gas passes through the gas vent path to apply force against the flex region and disengage the seal from the pressure-release vent, allowing the gas to exit through the pressure-release vent.

  • Patent number: 10188097
    Abstract: A device for the storage of a corneal specimen has means for the reception and entrapment of a corneal specimen, connected to the means for the creation of a pressure gradient with overpressure on the endothelial side and to the preservation medium circulation means in the layouts that present the means for the reception and entrapment of the cornea specimen. The means for the reception and entrapment of the corneal specimen entrap the sclera ciliary zone surrounding the cornea in an airtight manner to delimit a separate endothelial chamber and epithelial chamber in which the preservation medium can circulate with an overpressure in the endothelial chamber; The intermediate component and the endothelial lid comprise inlet and outlet orifices for the preservation medium which are connected to the means for the circulation of the preservation medium and the creation of a pressure gradient between the endothelial chamber and the epithelial chamber with overpressure in the endothelial chamber.

    Abstract: Various systems and techniques for inserting an intraocular lens are disclosed. In particular implementations, a system and a technique for inserting an intraocular lens may include the ability to move, in response to a force being applied in a first direction along a longitudinal axis, a first plunger tip along the longitudinal axis and into a delivery cartridge to fold an intraocular lens and move in a second direction along the longitudinal axis in response to the applied force being reduced. The system and the technique may also include the ability to engage a second plunger tip and move, in response to a force being applied in the first direction along the longitudinal axis, the second plunger tip along the longitudinal axis and into the delivery cartridge to insert the intraocular lens.

  • Patent number: 10092075
    Abstract: The packages described by this invention all have reduced “head space,” that is, the distance from lid to lens. Packages contain dimples to achieve this reduced head space. Specifically, packages are designed with dimple sag equal to or less than 1.90-mm, or volume displaced equal to or less than 360 ?l. Combined with the existing primary packaging, it has been found that such conditions provide for reduction in folded lens rate during shipping and handling. As well, lenses stored or having an extended time in low head space packages in a “foil down” orientation now have characteristics closer lenses stored in a “foil up orientation”.

  • Publication number: 20140183063
    Abstract: A plastic container for storing a hydrogel contact lens in a liquid, the container comprising: a cavity and a substantially flat flange that extends in a plane around the opening periphery of the cavity, and the flange having a sealing area round the circumference of the cavity. Furthermore, the sealing area has a micro-texture pattern. When sealing the container with a flexible cover sheet which is a laminate material having a metal foil layer and at least one polymer layer to form a storage package of the soft contact lens, the micro-texture pattern of the sealing area engages a laminate foil cover and displaces water beads present between the laminate foil cover and the plastic container in the sealing area around the cavity to form a heat seal.

  • Patent number: 8763794
    Abstract: The present disclosure provides a contact lens package containing a contact lens in a compressed state. In one exemplary embodiment, the overall internal depth of the package is less than the natural sagittal depth of the contact lens. Different single-use contact lens package shapes and configurations may be used. In some embodiments, a spring disc is included in the packages to help present the contact lens to the user when the package is opened. The contact lens packages may be adhered or clipped to a card or other carrier sheet, and may be housed in a number of different secondary packages.

  • Publication number: 20140174956
    Abstract: A container (1) for accommodating an ophthalmic lens during a lens treatment process has a longitudinal axis (12) and comprises a containment portion (2), a mounting portion (3), and a retaining element (4). The containment portion (2) comprises a tubular section (21) and a bottom (22) protruding convexly towards the outside at one end of the tubular section (21) and has a number of apertures (23, 24). The mounting portion (3) comprises flow openings and an access opening (11) at an end remote from the containment portion (2). The retaining element (4) prohibits the lens from being washed out of the containment portion (2) and further permits access of a gripper into the containment portion (2) for insertion and removal of the lens. The mounting portion (3) extends from the access opening (11) to the tubular section (21) in a manner to enable introduction of the containment portion (2) of another such container (1) into the mounting portion (3) through the access opening (11).

  • Patent number: 8757367
    Abstract: A lens care system and method for venting gas to release pressure from a container, such as generated in peroxide-based lens treatment. A seal formed between a deformable cap and a container cup prevents release of liquid, but deformation of the cap under the influence of pressure generated within the container temporarily releases the seal to permit venting of gas.

  • Publication number: 20140102917
    Abstract: Providing a system which can exhibit a desired effect of improving hydrophilicity of a contact lens without causing adverse influences on sense of use of the contact lens and a cleaning effect, and which can effectively prevent adhesion of lipid stain. Also providing a packaging solution for the contact lens which can effectively suppress or prevent reduction of its viscosity with time even when the packaging solution is sterilized by heating. The contact lens is immersed in an aqueous solution which contains a low-molecular weight hyaluronic acid having a molecular weight of not higher than 80,000, or a salt or derivative thereof, and which has a pH of 6.0-8.0 and an osmotic pressure of 220-380 mOsm.

  • Patent number: 8651774
    Abstract: There is described a method for the removal of a contact lens (30) from a container (10), with a contact lens (30) being immersed in a liquid (20) which is held in a container (10), and the contact lens (30) being removed from the container (10) together with at least a portion of the liquid (20) through a removal tube (3) which is dipped into the liquid (20) within the container (10). First the container (10) containing the liquid (20) and the immersed contact lens (30) is closed pressure-tight with a lid (2), which comprises the removal tube (3) and a pressure tube (5). Both, the removal tube (3) and the pressure tube (5), are guided through the lid (2). After the closing of the container (10) with the lid (2) an overpressure is applied to the interior of the closed container (10) through the pressure tube (5). The overpressure is applied such that the contact lens (30) and the liquid (20) are pressed into the removal tube (3) and removed together therethrough.
