Patent ID: 8574239

Claim:
An intraocular lens insertion device for use with an intraocular lens having an optic part with a first surface, a second surface opposite the first surface, and an outer edge between the first and second surfaces, said insertion device comprising: a main body defining a lens travelling axis and including a lens placement portion configured to have the intraocular lens placed thereon, a transition portion to deform said intraocular lens', a nozzle portion to discharge said intraocular lens and a distal end; and a lens push-out mechanism to push out said intraocular lens placed on said lens placement portion, wherein said lens push-out mechanism includes a plunger to push out said intraocular lens and a slider having a lens contact part larger than said plunger, wherein said slider is provided with an operating part projected outwardly from said main body and a lens holding part that holds one surface of an optic part of said intraocular lens, wherein said main body transition portion and said slider lens holding part are respectively sized, shaped and arranged relative to one another such that as said slider pushes said intraocular lens along the lens travelling axis through said transition portion and towards said nozzle, said slider lens holding part will apply force to said first surface of said intraocular lens optic part in a direction transverse to said lens travelling axis while said transition portion engages laterally spaced portions of said outer edge thereby gradually folding said intraocular lens about said lens holding part as said intraocular lens moves toward the distal end of said main body through said transition portion, and wherein said intraocular lens is discharged from said nozzle portion by said plunger after said lens is folded by said transition portion and said slider.
