An instrument for inserting an intraocular lens capable of securely and safely pushing out the lens by a simple structure. An instrument (1) for inserting comprises: a body (3) having a lens placement part (8) on which the lens (2) with a pair of loop parts (2b) at its optic part (2a) is installed,
An instrument for inserting an intraocular lens capable of securely and safely pushing out the lens by a simple structure. An instrument (1) for inserting comprises: a body (3) having a lens placement part (8) on which the lens (2) with a pair of loop parts (2b) at its optic part (2a) is installed, a transition part (12) deforming the lens (2), and a nozzle part (11) discharging the lens (2); and a lens push-out mechanism (4) pushing out the lens (2) placed on the lens placement part (8). The lens push-out mechanism (4) comprises a plunger (16) pushing out the lens (2) and a slider (15) having a lens contact part (20) larger than the plunger (16). The slider (15) comprises an operation part (23) projected to the outside of the body (3).

1. A method, comprising the steps of: pushing an unfolded intraocular lens, having an optic part with a first optical surface, a second optical surface opposite the first optical surface, and an outer edge between the first and second optical surfaces out of a lens placement portion of an injector having a plunger and into a tapered transition portion such that a portion of the optic part is on a central lens traveling axis of the tapered transition portion;folding the unfolded intraocular lens as the intraocular lens moves along the central lens travelling axis and through the tapered transition portion by applying a force to the first optical surface of the portion of the optic part that is on the central lens travelling axis, and in a direction transverse to the central lens travelling axis, while the tapered transition portion engages laterally spaced portions of the outer edge and folds the intraocular lens about the portion of the first optical surface to which force is applied; andpushing the folded intraocular lens along the central lens travelling axis, out of the tapered transition portion and through a nozzle. 2. A method as claimed in claim 1, wherein pushing an unfolded intraocular lens comprises pushing the unfolded intraocular lens with a slider out of the lens placement portion and into the tapered transition portion. 3. A method as claimed in claim 1, wherein the first optical surface of the folded intraocular lens is in compression and the second optical surface of the folded intraocular lens is in tension. 4. A method as claimed in claim 1, wherein folding the unfolded intraocular lens comprises folding the unfolded intraocular lens by moving the intraocular lens with a slider, which is movable relative to the plunger, along the central lens travelling axis and through the tapered transition portion while applying a force to a portion of the first optical surface of the intraocular lens on the central lens travelling axis with the slider and in a direction transverse to the central lens travelling axis while the tapered transition portion engages laterally spaced portions of the outer edge and folds the intraocular lens about the portion of the first optical surface to which force is applied. 5. A method as claimed in claim 4, wherein pushing the folded intraocular lens comprises pushing the folded intraocular lens with the plunger along the central lens travelling axis, out of the tapered transition portion and through the nozzle. 6. A method as claimed in claim 4, further comprising the steps of: preventing movement of the plunger prior to movement of the slider; andpermitting movement of the plunger in response to movement of the slider. 7. A method as claimed in claim 1, wherein pushing the folded intraocular lens comprises pushing the folded intraocular lens with the plunger, that is movable relative to a slider, along the central lens travelling axis, out of the tapered transition portion and through a nozzle. 8. A method as claimed in claim 1, further comprising the step of: storing the unfolded intraocular lens in an unfolded state in the lens placement portion. 9. A method for use with an intraocular lens having an optic part with a first optical surface, a second optical surface opposite the first optical surface, and an outer edge between the first and second optical surfaces, the method comprising the steps of: pushing the intraocular lens with a slider, which is movable relative to a plunger, along a lens travelling axis, out of the lens placement portion and into the tapered transition portion;deforming the intraocular lens as the intraocular lens moves along the lens travelling axis and through the tapered transition portion by applying a force to a portion of the first optical surface of the intraocular lens in a direction transverse to the lens travelling axis while the tapered transition portion engages laterally spaced portions of the outer edge and folds the intraocular lens about the portion of the first optical surface to which force is applied;pushing the deformed intraocular lens along the lens travelling axis, out of the tapered transition portion and through a nozzle;preventing movement of the plunger prior to movement of the slider; andpermitting movement of the plunger in response to movement of the slider. 10. A method for use with an intraocular lens having an optic part with a first optical surface, a second optical surface opposite the first optical surface, and an outer edge between the first and second optical surfaces, the method comprising the steps of: pushing the intraocular lens along a lens travelling axis, out of a lens placement portion and into a tapered transition portion;deforming the intraocular lens by moving the intraocular lens with a slider, which is movable relative to a plunger, along the lens travelling axis and through the tapered transition portion while applying a force to a portion of the first optical surface of the intraocular lens with the slider in a direction transverse to the lens travelling axis while the tapered transition portion engages laterally spaced portions of the outer edge and folds the intraocular lens about the portion of the first optical surface to which force is applied; andpushing the deformed intraocular lens along the lens travelling axis, out of the tapered transition portion and through a nozzle;wherein the slider includes an abutment part that engages the lens outer edge and a lens holder that extends beyond the abutment part and over the first optical surface. 11. A method as claimed in claim 10, further comprising the step of: pivoting the lens holder into contact with the portion of the first optical surface. 12. A method as claimed in claim 10, further comprising the steps of: driving the lens holder into contact with the portion of the first optical surface with the tapered transition portion as the slider moves along the lens travelling axis and through the tapered transition portion. 13. A method, comprising the steps of: pushing an unfolded intraocular lens, having an optic part with a first optical surface, a second optical surface opposite the first optical surface, and an outer edge between the first and second optical surfaces, along a lens travelling axis, out of a lens placement portion and into a tapered transition portion;folding the unfolded intraocular lens as the intraocular lens moves along the lens travelling axis and through the tapered transition portion by applying a force to a portion of the first optical surface of the intraocular lens on the lens travelling axis and in a direction transverse to the lens travelling axis while the tapered transition portion engages laterally spaced portions of the outer edge and folds the intraocular lens about the portion of the first optical surface to which force is applied;pushing the folded intraocular lens with a plunger, that is movable relative to a slider, along the lens travelling axis, out of the tapered transition portion and through a nozzle;preventing movement of the plunger prior to movement of the slider; andpermitting movement of the plunger in response to movement of the slider.
