Abstract: A device for dispensing a mist of an ophthalmic fluid includes a discharge opening for said mist, a mixing chamber communicating with said discharge opening, an air chamber holding a volume of air, a first drive operable to expel air from said air chamber, a fluid chamber for holding a volume of the fluid to be dispensed and communicating with said mixing chamber, a second drive for delivering a predetermined dose of said fluid to said fluid chamber, said air chamber communicating with said fluid chamber and with said mixing chamber, said device establishing one flow of expelled air flowing into said fluid chamber, so as to force liquid from said fluid chamber into said mixing chamber, and another flow of said expelled air flowing past said fluid chamber into said mixing chamber.
