Abstract
An intraocular lens inserting instrument capable of folding a lens and pressing it by a plunger to discharge it into an eye and alternatively capable of taking out the folded lens by tweezers. The intraocular lens inserting instrument for inserting a foldable intraocular lens into an eye has a tubular body for allowing the intraocular lens to pass through it and introducing it into the eye, and a plunger for pressing the intraocular lens to discharge it into the eye, wherein the intraocular lens is folded by a folding member provided at a lens placing section. The lens placing section has an open/close lid so that the folded intraocular lens is accessible to be held by the tweezers.
Claims15
A preset intraocular lens inserting instrument, comprising:
- a tubular body that defines a longitudinal axis and includes a main portion on the longitudinal axis, a nozzle on the longitudinal axis that is configured to be inserted into the eye, and a lens placing section located on the longitudinal axis between the main portion and the nozzle;
- an unfolded intraocular lens located within the lens placing section such that at least a portion of the unfolded intraocular lens is on the longitudinal axis;
- a folding member, movable relative to the lens placing section between a first position and a second position, that folds the unfolded intraocular lens while moving from the first position to the second position;
- and
- a plunger on the longitudinal axis and movable through the tubular body to push the folded intraocular lens into the eye;
- wherein the plunger and the folding member are operably associated with one another such that the plunger is prevented from moving into contact with the unfolded intraocular lens within the lens placing section when the folding member is in the first position and the plunger is not prevented from moving into contact with the folded intraocular lens when the folding member is in the second position.
A preset intraocular lens inserting instrument that inserts a folded intraocular lens into an eye, comprising:
- a tubular body defining a longitudinal axis along which said intraocular lens is guided to the eye;
- a plunger movable along said longitudinal axis that presses and discharges said intraocular lens into the eye;
- a lens placing section located along said longitudinal axis in said tubular body to contain said intraocular lens in an unfolded state;
- and
- a folding member, which is movable relative to the lens placing section, that folds said intraocular lens in said lens placing section by moving from a first position where said intraocular lens is unfolded to a second position where said intraocular lens is folded;
- wherein said folding member prevents said plunger from contacting said intraocular lens before the folding of said intraocular lens and permits said plunger to contact said intraocular lens after the folding of said intraocular lens.
