摘要： 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.
