Abstract
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. A flexible bar is mounted to the outer housing member, and the free end of the flexible bar is adapted to be engaged with the facial tissue below an eye to displace the facial tissue, and thus displace the lower eyelid, to direct the medicament into the exposed ocular cul-de-sac of the eye. The flexible member is engaged with the facial tissue by moving the outer housing member toward the eyepiece, which simultaneously displaces the lower eyelid and allows the medicament dispensed from the vial to fall into the exposed ocular cul-de-sac of the eye.
