ABSTRACT:
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.
