Abstract: An intraocular lens wherein an outer edge of a support part has a curved concave shape at a base thereof and extends therefrom toward a tip thereof with a curved convex shape having a radius of curvature of 5.25 to 7.50 mm. In a region where a Y coordinate of an orthogonal coordinate system is 1.0 mm or greater, an origin of the coordinate system being a geometric center of an optical part, an inner edge of the support part is positioned between shapes obtained by offsetting the outer edge of the support part by 0.2 mm and by 1.0 mm towards the X-axis origin. The tip of the support part is positioned in a region where the Y coordinate is greater than a radius of the optical part, outside a circle with a radius of 5.0 mm centered on the origin.
