1. An ocular treatment apparatus for applying medicament into an eye, said apparatus comprising:
- a nozzle having an orifice defined therein for releasing medicament into the eye;
storage means including a storage cavity in fluid communication with said nozzle orifice for holding medicament for release into the eye;
a vial defining a first cavity for holding a first medicament, said first cavity being in fluid communication with said storage cavity, said vial further defining a second cavity for holding a second medicament;
means for controllably placing said first cavity of said vial in fluid communication with said second cavity of said vial for mixing in said storage cavity the first and second medicaments into a mixed medicament; and
displacement means for displacing a substantially predetermined volume of mixed medicament within said storage cavity through said nozzle orifice for release into the eye.

Abstract
An ocular treatment apparatus for applying medicament into an eye has a vial defining a vial cavity for holding medicament. A nozzle is attached over an opening in the vial and is in fluid communication with the vial cavity for releasing drops of medicament. A piston member is suspended within the vial and slideably engaged within the vial cavity for displacing a substantially predetermined volume of medicament through the nozzle for release into the eye.
