Insertion device for intraocular lens
First Claim
1. An insertion device for an intraocular lens, comprising:
- a lens-holding section having a cavity for accommodating an intraocular lens, the intraocular lens having a deformable optical portion and being held in the cavity at a standby position in a state in which no stress acts on the optical portion of the lens;
a deforming section for deforming the lens to a reduced size;
an insertion tube through which the deformed lens is inserted into an eye;
a pusher mechanism for pushing and inserting the lens into the eye through the insertion tube;
an injection portion to be used for injecting a lubricant into at least either the cavity of the lens-holding section or the interior of the insertion tube, the lubricant enabling smooth passage of the intraocular lens through the insertion tube; and
an indicating mark for indicating quantity of the injected lubricant.

Abstract
An insertion device for an intraocular lens includes a lens-holding section having a cavity for accommodating an intraocular lens, a deforming section for deforming the lens to a reduced size, an insertion tube through which the deformed lens is inserted into an eye, a pusher mechanism for pushing and inserting the lens into the eye, and a lens-moving mechanism for moving the lens from a standby position to an insertion position at which the pusher mechanism can push and insert the lens into the eye. A lubricant is injected into the interior of the insertion tube and/or the cavity of the lens-holding section for smooth insertion of the lens. The insertion device has an indicating mark for indicating quantity of the injected lubricant. Further, the insertion device includes an erroneous operation prevention member for preventing accidental operation of the lens-moving mechanism.
