Abstract
An eyecup (10) having a rim portion (14) that conforms to an orbit portion which surrounds an eye (12) on the face of a person is placed over the eye. The eyecup (10) forms a liquid confining chamber (45) adjacent the eye (12). The skin above and below the eye (20, 22) is drawn away from the eye (12), with the eyecup being pushed against the skin (20, 22) such that the rim portion (14) applies sufficient pressure against the skin for holding the eye (12) open. Eyewash is delivered and drained to and from the chamber (45) by inlets (50, 52) and an outlet (60). The inlets and the outlets are interchangeable. Eyewash delivered into the chamber (45) is directed such that the flow of the eyewash first contacts a surface of the eye (12) which is spaced a distance from the corneal portion (70) of the eye and then flows over and across the entire eye.
