ABSTRACT:
The invention is a mold and method for using the mold to make a multi-stage intraocular lens. The mold is provided with a gate in fluid communication with a lens portion and/or haptic portion of the mold core. In addition, a gasket is provided around the mold core. As molding material is introduced into the mold via the gate, a vacuum is drawn around and through the gasket to evacuate air trapped in the mold core and to help pull the material through the mold core.
