The invention relates to a device for cleaning and sterilizing a soft plastic lens in which the device comprises only three elements; namely, a container for receiving a cleaning or a sterilizing liquid and a lens, a strainer and a cap having a plurality of radially extending impellers. The cap encloses the open end of the container and with movement of the two elements so assembled in a back and forth direction, the cleaning or sterilizing liquid is agitated and swirled with the lens being moved therethrough. The strainer is used as an intermediate member that is enclosed by the cap, when the device is inverted after cleaning, rinsing and sterilizing of the lens, to permit the lens to settle onto the central partition of the strainer before the cap is removed to allow the sterilizing liquid to drain from the container. With removal of the container from the strainer, the lens is retained on the strainer and available for pick-up by a sterile inserter.

A device for cleaning and sterilizing a soft, plastic lens, comprising: an elongated, hollow, transparent container having a generally circular bottom wall, a continuous side wall encircling the periphery of the bottom wall and a generally circular open end opposite the bottom wall for selectively receiving a lens cleaning liquid and a lens sterilizing liquid and the lens; a strainer having a first generally hollow, cylindrical open end insertable and extending into the open end of the container, a second generally hollow, cylindrical open end extendable beyond the open end of the container and a flat, perforated portion arranged between the first and second open ends of the strainer for receiving the lens on the face of the flat portion facing the first open end of the strainer upon inversion of container to remove the sterilizing liquid and the container from the strainer; a removable cap having a generally flat portion, including a first surface and a second surface, and a peripheral flange extending from the portion in the direction of the first surface for selectively enclosing the open end of the container and the second open end of the strainer; and a plurality of impellers on the first surface of the removable cap, each of the impellers being similarly oriented and inclined in a radial direction from a high point at the center of the first surface to a low point on the first surface adjacent the flange and each side of which is pitched at a different angle.
