Abstract
Method and apparatus for molding an IOL comprising first and second mold halves each having an optic forming surface and haptic forming surfaces which together define a mold cavity in the shape of the IOL to be molded therein when the mold halves are assembled together. An injection port is formed and connects to one of said haptic forming surfaces or the optic forming surface wherethrough a polymerizable material is injected into the mold cavity. A venting port is formed and connects to another haptic wherethrough air escapes from the mold cavity as the polymerizable material is injected through the injection port.
