Ocular treatment device
First Claim
1. A method of creating a directed jet and/or stream of droplets forming a unit dose of treatment liquid comprising discharging such liquid from a sealed enclosure through an opening in a wall section thereof, the opening having a diameter in the range 20 to 200 μ
- m, by pressurising the enclosure at a rate sufficent to generate a jet and/or stream of droplets with a minimum diameter of 20 μ
m and sufficient momentum to sustain substantially linear movement over a predetermined distance.

Abstract
A unit container for a treatment fluid comprises a sealed enclosure of which one wall section thereof is formed with at least one opening. The enclosure is pressuriseable to discharge its contents thorough the opening or openings, which is or are of sufficient diameter to enable the generation of a jet and/or discrete droplets of treatment fluid discharged therefrom. The one wall section is typically a flat section of the enclosure wall, and the enclosure is typically a blister pack, with the wall section at a planar base of the blister. However the one wall section may be dome-shaped and formed with at least one opening in the top region of the dome. Containers of the invention may be provided in packages, for example in strip form or in planar arrays. Dispensing devices are described for discharging their content in treatment.
