An intraocular lens injection instrument for storing a soft intraocular lens (IOL) (100) including an optic part (101) made of acrylate resin having viscosity in a housing (10) of the instrument, and feeding out the IOL from the housing through a front end (2a) of the instrument by use of a push rod (6) of the instrument to inject the IOL into a patients eye, is characterized in that the instrument comprises a storage part (70) provided with a pair of holding stands (73) arranged opposite to each other in a front-rear direction along a movement axis (L) of the push rod to hold the optic part, the holding stands including upper surfaces (71) on which the optic part is to be placed and having a predetermined height to place the optic part above and out of the movement axis during storage, the upper surfaces have a surface roughness of arithmetical mean roughness Ra 6.3 or less so that the optic part is allowed to adhere to the upper surfaces by the viscosity of the optic part and the surface roughness of the upper surfaces, and the storage part is vertically movably attached to the housing so that the optic part is placed above and out of the movement axis when the storage part is positioned upside and the optic part is placed on the movement axis when the storage part is positioned downside.
