PURPOSE: To provide a lens having haptics having improved resistance to rupture by substantially orienting a haptic material extending outward by sticking to an optical part main body and a lens periphery, and forming a material of an optical part so as to have a substantially balanced orientation. CONSTITUTION: A lens 20 of an integrated intraocular lens is formed in a shape suitable for rightly adjusting a focus according to a method well known by an expert of a field of manufacturing the intraocular lens, and is formed of an integrally formed support element or an optical element having haptics 24 extending from there or a lens 20. The lens 20 is generally worked so as to impart a further sufficiently desirable orientation instead of being manufactured from a randomly oriented conventional material, and is manufactured from a material having extremely improved resistance to rupture. Generally, a material of a short bar shape is compressively molded to obtain these properties, and a desirable orientation different between a central optical area and an outside periphery is imparted, and a mechanical property in an area where the haptics 24 are positioned is improved.
