The present invention discloses an apparatus for cleaning ophthalmic devices. The apparatus has a conveying system for transporting lens mold carriers to a cleaning station. The cleaning station has at least one movable cleaning assembly which is situated above the lens mold carrier and has a recess. When the cleaning assembly is lowered to the lens mold carrier, a substantially enclosed or enclosed cavity containing the lens mold is created by the carrier and the recess of the cleaning assembly. Compressed gas is injected into the cavity to dislodge any debris that may be present on the lens molds, and a vacuum is employed to remove gas and debris from the cavity.

The present invention discloses a method for cleaning contact lens molds. The method comprises the steps of placing a contact lens mold within an enclosed or substantially enclosed area, directing an inflow of gas under pressure into the enclosed area against the contact lens mold, and providing an outflow of gas from the enclosed area, thereby dislodging and removing debris.

A mold assembly for producing a plurality of contact lenses includes a front curve fixture assembly, a base curve fixture assembly and a plurality of mold cavities. The plurality of mold cavities are defined by a surface on either the front or the base curve fixture assembly and is disposed in a zig-zag manner relative to each other. Each of the plurality of mold cavities includes a retention edge for complimentary engagement with a mold. The retention edge of a first subset of the plurality of mold cavities is spaced apart from a selected fixture mating surface at a first distance and the retention edge of a second subset of the plurality of mold cavities being spaced apart from the selected fixture mating surface at a different second distance so that a plurality of molds may be placed in adjacent cavities so as to overlap the mold flanges.
