ABSTRACT:
The combination of a squeezable bottle containing an ophthalmic fluid and a detachable applicator apparatus for efficiently spraying the ophthalmic fluid to an eye. The applicator apparatus includes a body having an inlet end portion for attaching the applicator apparatus to the bottle and an outlet end portion for centering the applicator apparatus on the eye, a circular outer planar flange portion extending outwardly in covering relationship from said body circular outlet portion to limit the intrusion of the outlet end portion into the bony orbital ocular opening which surrounds the eye; and a soft resilient seal for sealing a nozzle when the applicator apparatus is not used. The method comprises the steps of removing a cap from a storage bottle; discarding the cap, adding a nozzle to an outlet of the storage bottle, attaching an applicator to the storage bottle; opening an eyelid to spray a small portion of the ophthalmic fluid from the storage bottle on to the eye; inserting a cylindrical outlet end of the applicator body into the bony orbital ocular opening which surrounds the person's eye to center the discharge nozzle on the eye; squeezing the storage bottle to spray a small portion of the ophthalmic fluid on the eye; and attaching a cap to the applicator to seal the storage bottle and prevent the contamination of the storage bottle.
