摘要: A one-piece intraocular lens realizing adhesion of the intraocular lens to the inner surface of a capsule more advantageously by viscosity imparted to the intraocular lens, and being deployed more positively after it is inserted into the capsule and secured therein while being positioned at a specified location. The intraocular lens has an optical portion (12) and supporting portions (16, 16) that are formed integrally with a soft material exhibiting viscosity, wherein viscosity reducing portions (32, 32) having irregularities are formed on at least one-end faces of the supporting portions (16, 16) in the longitudinal direction.

摘要: Provided is technology which can prevent plunger deformation and further stabilize an intraocular lens insertion operation, even when an insertion tube section of an intraocular lens insertion apparatus has been further reduced in terms of the diameter thereof and has been made flatter. The intraocular lens insertion apparatus includes: a tip end region where a plunger comes into contact with an intraocular lens main body and an intraocular lens holding section; and a bar-shaped section extending from the rear end of this tip end region to the rear of the plunger. The bar-shaped section has a fixed thickness in the direction of the optical axis of the intraocular lens, and has an increasing thickness in a portion where the distance from the tip end of the tip end region is equal to or greater than a predetermined distance in a direction perpendicular to the optical axis direction and perpendicular to the plunger advancement direction.

摘要: Provided is technology which can prevent the circumferential section of the end surface of a tip end opening from being damaged when an intraocular lens is extruded from an insertion apparatus, even when an insertion tube of the intraocular lens insertion apparatus has been further reduced in size. Provided is an intraocular lens insertion apparatus in which the end surface of a tip end opening (10j) in a tip end section (10a) of an insertion tube is an inclined surface that is inclined with respect to a surface (M) perpendicular to a central axis (L) of the insertion tube, and also the angle of inclination, with respect to the surface (M) perpendicular to the central axis (L) of the insertion tube, of the end surface of the tip end opening is larger toward a base end section (101) than toward a tip end section (100), wherein a predetermined region of the circumferential section toward the base end section (101) of the end surface of the tip end opening (10j) has a curved shape that protrudes toward the outside, and has a radius of curvature (R4) that is equal to or less than the radius of curvature of another region of the circumferential section.
