INTRAOCULAR LENS
A first region (R1) is a circular region located at the centermost position. A first refractive power is uniformly added to the first region (R1) regardless of the distance from an axis (O) of a lens part (2). A second region (R2) is a ring-like region located adjacent to the first region (R1) at an...

| description | A first region (R1) is a circular region located at the centermost position. A first refractive power is uniformly added to the first region (R1) regardless of the distance from an axis (O) of a lens part (2). A second region (R2) is a ring-like region located adjacent to the first region (R1) at an outer side of the first region (R1). In the second region (R2), a refractive power is increased or decreased from the first refractive power as the distance from the axis (O) becomes larger. An outer region (RO) is a ring-like region located at an outer side of the second region (R2). A reference refractive power for focusing on a far point is added to the outer region (RO). An MTF curve at spatial frequency of 50 lp/mm relating to light passing through a region having a radius of 1.5 mm around the axis (O) of the lens part (2) has one maximal value and no minimal value in a range of a defocusing value of -0.5 D to 0.5 D. |
