A method of forming a mold insert used to produce an intraocular lens (IOL) mold is disclosed herein. The method includes providing stock material and cutting the stock material, which includes multiple cutting steps. The cutting steps are performed on transitional regions of supporting portions of the mold insert. Peripheral surfaces of the mold insert have varying roughness values, and supporting portions of the mold insert have a greater roughness than the optical portion of the mold insert. An IOL is also disclosed herein that is formed using an IOL mold that is injection molded using the mold insert. A method of forming the IOL is also disclosed herein.

Method and assembly for forming an intraocular lens

A method and assembly for removing an intraocular lens from an injection molded mold half. With the method and the assembly, first spill ring material is removed from the mold half. Subsequently, the mold/lens-assembly is subjected to an oscillating mechanical load without substantial deformation of at least a part of the mold half that is in direct contact with the lens body. The oscillating mechanical load has an oscillation frequency which is in a range that excites the mold/lens-assembly to break bonds between the intraocular lens and the mold half. After that, a static mechanical push force is exerted on the bottom side of the mold half to at least partly separate the intraocular lens from the mold half.
