Claim:
1. An intraocular lens comprising: an optical part formed of a bendably deformable soft material; and a support part integrally provided to the optical part, the support part extending from the optical part toward an outer circumference side while inclining in a circumference direction, wherein an outer circumference side edge part of the support part has a curved concave shape at a base part thereof, and has a curved convex shape with a radius of curvature of 5.25 to 7.50 mm at a portion further to a tip side thereof than the base part, an inner circumference side edge part of the support part has a curved concave shape at a base part thereof, and with an orthogonal coordinate system for which a geometric center of the optical part is an origin point, a tangent line to the base part of the inner circumference side edge part is an X axis, and an orthogonal line to the X axis is a Y axis, in a region where a Y coordinate value is 1.0 mm or greater, the inner circumference side edge part of the support part is positioned between a shape such that the outer circumference side edge part of the support part is offset by 0.2 mm toward the origin point of the X axis and a shape such that the outer circumference side edge part is offset by 1.0 mm toward the origin point, and with the orthogonal coordinate system, a tip part of the support part is positioned in a region where the Y coordinate value is greater than a radius value of the optical part and outside a circumference of 5.0 mm in radius having the origin point as a center.
