<P>PROBLEM TO BE SOLVED: To provide an intraocular lens insertion instrument for stably pushing out an intraocular lens. <P>SOLUTION: The intraocular lens insertion instrument includes: an insertion part that has an inner wall for compactly folding a soft intraocular lens and a placement surface on which the intraocular lens before being pushed out is placed, and inserts the folded intraocular lens from the incision of an eyeball; and a cylindrical body which has the insertion part at the distal end and in which a pushing-out means for pushing out the intraocular lens placed on a pushing-out axis is arranged so as to be advanceable/retractable in an axial direction. A contact area with the intraocular lens, of the placement surface includes: a first area formed to have a surface state enabling predetermined frictional force required for holding the position of the intraocular lens to be generated; and a second area in which a part of the contact area is formed to have a surface state with very small projections/recessions to reduce the frictional force with respect to the first area in order to prevent the intraocular lens from being adhered to the placement surface. <P>COPYRIGHT: (C)2013,JPO&INPIT |
