ABSTRACT:
An inserting device for inserting an intraocular lens into the eye. An interference preventing portion is formed in a lens holding section which is provided with an opening/closing mechanism and is a part of a holder member attached to a body. An intraocular lens is held by the lens holding section such that its optical part made of an elastic material is deformed into a smaller shape. The tip portion of a support which is made of a different material from that of the optical part and which extends backward the optical part is received by the interference preventions portion. When a pusher rod of a pusher mechanism attached to the body is advanced, only the optical part is pushed by the pusher rod without causing interference between the pusher rod and the tip portion of the support, thereby inserting the intraocular lens into the eye. Therefore, the intraocular lens held by the lens holding section can be pushed out by the pusher rod of the pusher mechanism and safely inserted into the eye without causing deformation of the supports of the intraocular lens.
