Abstract
An intraocular lens insertion device capable of folding an intraocular lens into a predetermined shape without giving a local stress to the intraocular lens. The intraocular lens insertion device 2 may include a lens disposing part 15 for disposing an intraocular lens 4, a slider 7 for pushing out the intraocular lens 4, a plunger 8 for further pushing out the intraocular lens pushed out by the slider 7, a transition part 31 for deforming the intraocular lens 4 pushed out by the slider and the plunger, and a nozzle 32 for ejecting out the deformed intraocular lens 4.
Claims5
An insertion method, comprising the steps of:
- pushing an unfolded intraocular lens, having a lens optic and a lens outer edge, in a first direction;
- moving diametrically opposed portions of the lens outer edge in a second direction transverse to the first direction as the intraocular lens is being pushed in the first direction;
- and
- during the moving step, folding the intraocular lens by preventing a portion of the lens optic located between the diametrically opposed portions of the lens outer edge from moving in the second direction.
An insertion method as claimed in claim 15, wherein the step of pushing an unfolded intraocular lens comprises pushing the unfolded intraocular lens with a slider.
