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.
