  • Patent number: 5401259
    Abstract: A cartridge for actuating a piston-like or accordion-like dispenser-vial for applying medicament to an eye. The cartridge includes a housing for holding the dispenser-vial and a telescoping cylinder for compressing the dispenser-vial in the longitudinal direction to actuate the vial. The cartridge includes a locking mechanism for locking the telescoping cylinder to restrict its movement and a lever mechanism for releasing the cylinder from the locked position so that a drop is released from the dispenser. The housing includes a finger for engaging the lower eyelid and exposing the conjunctival cul-de-sac.

  • Patent number: 5366499
    Abstract: A prosthesis for implanting in an eye has a lens member and a double interface member which is coupled to the periphery of the lens member. The double interface member is comprised of a more superficial branch and a deeper branch which project out from the lens member. The double interface member has a plurality of pores for permitting the ingrowth of tissue to anchor the prosthesis to the eye. The double interface member also has an anatomical structure into which eye tissue is inserted, so as to become an immediate anchor to the eye and an immediate barrier to external pathogens.

  • Patent number: 5320845
    Abstract: An apparatus for simultaneously delivering more than one kind of medicament to an eye, without premixing of the medicaments within the apparatus. The apparatus includes a special nozzle assembly which precludes reentry of medicament expelled from the nozzle to prevent commingling of the medicaments. In this way, dosages of two or more medicaments may be simultaneously delivered to an eye without the need for creating a stable premixture of the medicaments.

  • Patent number: 5163929
    Abstract: An ocular treatment apparatus for applying medicament into an eye has a vial defining a vial cavity for holding medicament. A nozzle is attached over an opening in the vial and is in fluid communication with the vial cavity for releasing drops of medicament. A piston member is suspended within the vial and slideably engaged within the vial cavity for displacing a substantially predetermined volume of medicament through the nozzle for release into the eye.

  • Patent number: 5133702
    Abstract: An apparatus for applying medicament to an eye has an inner casing and an outer casing coupled to the inner casing and moveable relative thereto. An eyecup is supported on one end of the inner casing. The eyecup defines a surface shaped to conformably engage the facial tissue surrounding an eye. An ocular vial supported with the inner casing. The ocular vial holds medicament for release into an eye. An eyelid displacing member is coupled to the outer casing and slideably mounted through the inner casing. The eyelid displacing member includes a depresser tab adapted to engage the facial tissue below an eye. The depresser tab engages the facial tissue upon moving the outer casing toward the inner casing, thus displacing the lower eyelid to expose the ocular cul-de-sac. A dispensing member is supported by the outer casing. The dispensing member is adapted to actuate the ocular vial upon moving the outer casing toward the inner casing, to release medicament onto the exposed ocular cul-de-sac of the eye.

  • Patent number: 4946452
    Abstract: An ocular treatment apparatus for applying medicament into an eye has an inner housing member with an eyepiece on a free end thereof. The eyepiece defines an opening in one end thereof, and the opening has a peripheral edge shaped for engagement with the facial tissue surrounding an eye. A body portion of the inner housing member is coupled to the eyepiece and is dimensioned to receive a vial of medicament for application to the eye. An outer housing member of the apparatus has an open free end, which is slidably engaged over the inner housing member. The outer housing member has a displacement rod that projects inwardly from a closed end thereof in the axial direction of the apparatus. The displacement rod is engageable with a flexible vial supported within the body portion of the inner housing member. The displacement rod flexes the vial inwardly to dispense medicament therefrom into an eye.

  • Patent number: 4908024
    Abstract: An ocular self-treatment apparatus and self-treatment method for simplifying and improving the ease of ocular self-treatment. The apparatus is formed of a frame to be worn by the patient. The frame supports one or two light deviation apparatus. These apparatus deviate the visual access of the patient. The frame also supports one or two dispensers of ocular treatment material. A patient rotates his eye upwards and the light deviation apparatus allows him to observe the lower ocular area. The patient can then evert his lower eyelid and apply ocular treatment material to the cul-de-suc of the conjunctiva.

  • Patent number: 4792334
    Abstract: An occular treatment apparatus for applying liquid medicament from a reservoir is provided. The apparatus includes a tubular housing with a first open end adapted to conform to the shape of the facial area surrounding the eye socket. The housing is constructed and arranged to receive, hold and position a reservoir containing the liquid medicament. A sighting opening is included on the housing to properly orient the eye and distract the user from the drops of liquid medicament to be introduced into the eye. An eyelid displacement mechanism is supported on the first open end of the housing at a position diametrically opposed to the sighting opening. The displacement mechanism is adapted to evert the lower eyelid and expose the cul de sac.
