Improved corrective procedures for conductive keratoplasty are disclosed. The RVM includes an item supporting, rotating, sorting and conveyor unit, an upright storage chamber for such items, a safety apparatus to avoid operational hazards, a camera aided detection device for detecting at least one of a bar code on and other characteristics, e. The flow rate of the water is measured by a flow meter and in combination with the metering pump, a proper amount of surfactant is injected into the water line to produce a mixture with a desired surfactant concentration for removing contaminants. The inverter system be configured to inverter the stabilized power output to an output suitable for powering the AC load.
