An intraocular lens insertion instrument includes: a cylinder ( 10, 20, 60 ) provided with an insertion part ( 11 ) which is inserted in an eye through an incision formed in the eye; a push-out unit ( 30 ) which is mounted axially movably in the cylinder to push out an intraocular lens ( 40 ) placed in the cylinder to the outside through the insertion part; and a working pressure adjustment unit ( 22, 23, 24; 70, 72, 80, 81 ) which is set in contact with the push-out unit to adjust working pressure needed to move the push-out unit by changing frictional force on the push-out unit.
