摘要： An insertion device for inserting a deformable intraocular lens into the eye. The insertion device has a an enclosing member that is attached to the body of the insertion device and that has two hinge portions at a lens receiving section. Further, a retainer member is fitted onto the enclosing member and a holder fitted onto the body. The deformable intraocular lens is placed in the lens receiving section after the enclosing member is opened. When the holder is retracted, the intraocular lens is deformed by a tapered inner wall portion formed at a the tip end of the holder, so that the exterior size of the lens is reduced. Subsequently, a push rod supported by the body is advanced in order to insert the lens into the eye.

摘要： A deformable intraocular lens which does not deviate within the eye and is free from strains or deformation even when the tails of the supports are deformed by external force such as compression. The lens according to the invention has a deformable optical part which is made of an elastic material, and a plurality of supports which are made of a material different from that of the optical part and which are bonded to the optical part, each of the supports having, in a serial integration, a flexible tail, a rigid base which cuts off the transmission of stress generated by the deformation of the tail to the optical part, and an anchor which binds the support to the optical part, wherein the transitional part of the tail and the base is disposed outside the optical part. With this structure, even when the tails of the supports are deformed by external force, the tails themselves absorb the deformation stress and the rigid bases cut off transmission of the stress to the optical part.

摘要： A deformable intraocular lens which can be inserted in the eye through a smaller incision by being deformed to have a smaller shape. The lens according to the invention has a deformable optical part which is made of an elastic material, the optical part having a lens portion and a peripheral portion surrounding the lens portion. The peripheral portion is thinner than the center of the lens portion. A plurality of supports are made of a flexible material different from the material of the optical part. Each support has an anchor embedded in the optical part for bonding the support to the optical part. A plurality of reinforcing sections having a thickness larger than the peripheral portion of the optical part are provided at a plurality of positions on the peripheral portion of the optical part or in the proximity thereof. The anchors of the supports are embedded in the reinforcing section. The bonding strength between the optical part and the supports is enchanced and the thickness of the optical part is reduced. Thus, the optical part can be deformed in a smaller shape.

摘要： 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.

摘要： An intraocular-lens insertion device is adapted to deform a deformable intraocular lens into a smaller size and insert the intraocular lens into an eye via an insertion tube. An intraocular-lens guide is provided on the inner surface of the insertion tube. The guide may be a rail-shaped projection or a groove, which extends parallel to a direction along which the intraocular lens is pushed out. A stress release structure is provided on the insertion tube in order to release stress of the intraocular lens produced due to deformation thereof. Moreover, a frictional-resistance increasing structure is provided on the inner surface of the insertion tube to be located in the vicinity of the stress release structure. The frictional-resistance increasing structure increases frictional resistance between the inner surface of the insertion tube and the intraocular lens. The frictional-resistance increasing structure may be a roughened surface which completely or partially covers the inner surface of the insertion tube.

摘要： An insertion device is used to deform a deformable intraocular lens to a reduced size and insert the deformed lens into an eye through an insertion tube. The insertion device includes a push rod for pushing and inserting the lens into the eye, and a posture control member disengagably engaged with a tip end portion of the push rod. The posture control member prevents deflection of the push rod from a center axis. The engagement between the posture control member and the push rod is broken when the push rod arrives at a predetermined position during a step of advancing the push rod.
