Abstract
An intraocular lens insertion apparatus which allows the intraocular lens to behave more stably. The intraocular lens insertion apparatus includes a substantially tubular apparatus body which has, at a tip end thereof, an insertion tube part for inserting an intraocular lens in a folded state into an eye, the intraocular lens having a lens body and a support, a storage which stores the intraocular lens, and an extruding member which moves the intraocular lens in the insertion tube part by pushing the intraocular lens, and the extruding member has a tip end part having a first protrusion protruding to one side in a left-right direction and a second protrusion protruding to the other side in the left-right direction.
Claims6
An intraocular lens insertion apparatus comprising:
- a substantially tubular apparatus body which has, at a tip end thereof, an insertion tube part for inserting an intraocular lens in a folded state into an eye, the intraocular lens having a lens body and a long support which is connected at one end to the lens body;
- a storage which stores the intraocular lens;
- and
- an extruding member which slides in the apparatus body and moves the intraocular lens in the insertion tube part by pushing the intraocular lens, wherein
- the extruding member has a tip end part having a first protrusion protruding to one side in a left-right direction and a second protrusion protruding to the other side in the left-right direction in a front view of the extruding member in a direction in which the intraocular lens is extruded,
- during the movement of the intraocular lens in the insertion tube part by the extruding member,
- the first protrusion restricts a base end part of the support from moving to a front side of the intraocular lens in an optical-axis direction by abutting against the base end part from the front side in the optical-axis direction, and
- the second protrusion restricts a distal end part of the support nearer to a distal end thereof than the base end part from moving to the front side in the optical-axis direction by abutting against the distal end part from the front side in the optical-axis direction.
