Abstract:
Methods, devices, and systems for processing ophthalmic lenses, such as contact lenses, are described. The present devices and systems include a washing device, processing head or processing tip configured for use in processing an ophthalmic lens placed in a receptacle cavity to wash the ophthalmic lens. When the processing tip is placed in contact with the receptacle, the processing fluid in the well of the body of the processing tip is in fluid communication with the fluid in the cavity of receptacle. The volume capacity of the well is in addition to a volume capacity of the receptacle. The processing tip further has at least one port for fluid addition or removal.
