An intraocular lens insertion device 1 comprises a main body 2, and a slider 3 and a plunger 4 that are attached to the main body 2. Further, the intraocular lens insertion device 1 is of a preset type in which an intraocular lens 5 is placed inside the main body 2 in advance. The slider 3 includes a first abutting portion 21 for pushing up a supporting portion 7 (rear supporting portion 7a) arranged on a rear side of an optical part 6 with respect to a lens advancement axis A, and second abutting portions 22a, 22b abutting against an outer edge of a rear portion of the optical part 6. ## Claims ### Claim 1 An intraocular lens insertion device comprising: a lens placement section for placing an intraocular lens having an optical part and one or more supporting portions provided on an outer edge of said optical part; a transition section for deforming said intraocular lens; a nozzle section for releasing said intraocular lens; a slider for pushing out said intraocular lens placed in said lens placement section; and a plunger for releasing said intraocular lens pushed out by said slider from said nozzle section, wherein said slider includes: a first abutting portion for pushing up said supporting portion arranged on a rear side with respect to a lens advancement axis; and one or more second abutting portions abutting against an outer edge of a rear portion of said intraocular lens. ### Claim 2 (depends on 1) The intraocular lens insertion device according to claim 1, wherein said second abutting portions are provided outside said first abutting portion with respect to the lens advancement axis. ### Claim 3 (depends on 1) The intraocular lens insertion device according to claim 1, wherein said first abutting portion slants downward in a lens advancement direction. ### Claim 4 (depends on 1) The intraocular lens insertion device according to claim 1, wherein at least one of said second abutting portions includes: an x-direction abutting surface having a face substantially perpendicular to a surface of said optical part; and a y-direction abutting surface having a face substantially parallel with the surface of said optical part. ### Claim 5 (depends on 1) The intraocular lens insertion device according to claim 1, further comprising a guiding portion for guiding the outer edge of said optical part to said second abutting portions. ### Claim 6 (depends on 1) The intraocular lens insertion device according to claim 1, wherein said second abutting portions are provided as a left-right pair centered about the lens advancement axis. ### Claim 7 (depends on 2) The intraocular lens insertion device according to claim 2, wherein said first abutting portion slants downward in a lens advancement direction. ### Claim 8 (depends on 2) The intraocular lens insertion device according to claim 2, wherein at least one of said second abutting portions includes: an x-direction abutting surface having a face substantially perpendicular to a surface of said optical part; and a y-direction abutting surface having a face substantially parallel with the surface of said optical part. ### Claim 9 (depends on 3) The intraocular lens insertion device according to claim 3, wherein at least one of said second abutting portions includes: an x-direction abutting surface having a face substantially perpendicular to a surface of said optical part; and a y-direction abutting surface having a face substantially parallel with the surface of said optical part. ### Claim 10 (depends on 2) The intraocular lens insertion device according to claim 2, further comprising a guiding portion for guiding the outer edge of said optical part to said second abutting portions. ### Claim 11 (depends on 3) The intraocular lens insertion device according to claim 3, further comprising a guiding portion for guiding the outer edge of said optical part to said second abutting portions. ### Claim 12 (depends on 4) The intraocular lens insertion device according to claim 4, further comprising a guiding portion for guiding the outer edge of said optical part to said second abutting portions. ### Claim 13 (depends on 2) The intraocular lens insertion device according to claim 2, wherein said second abutting portions are provided as a left-right pair centered about the lens advancement axis. ### Claim 14 (depends on 3) The intraocular lens insertion device according to claim 3, wherein said second abutting portions are provided as a left-right pair centered about the lens advancement axis. ### Claim 15 (depends on 4) The intraocular lens insertion device according to claim 4, wherein said second abutting portions are provided as a left-right pair centered about the lens advancement axis. ### Claim 16 (depends on 5) The intraocular lens insertion device according to claim 5, wherein said second abutting portions are provided as a left-right pair centered about the lens advancement axis.
