1. An apparatus for applying medicaments to an eye, comprising:

  • a vial;

    a means for partitioning said vial into a first medicament chamber and a second medicament chamber which precludes commingling of medicament in the first chamber with medicament in the second chamber; and

    a nozzle coupled in fluid communication with the first and second medicament chambers, the nozzle defining a tight interface therein normally in a closed position which prevents passage of medicament through the nozzle and which opens in response to a flow of medicament of sufficient pressure to permit passage of said flow of medicament through the nozzle for release into the eye.
