- the optical properties of the phakic intraocular lens 1 provided with the hole 6 are almost the same as those of a phakic intraocular lens without the hole 6 .
- the diffraction grating 5 can form a single focal point because the diffraction grating 5 has the grooves which are formed such that the farther an interval between the grooves is from the center of the diffraction grating 5 , the smaller the interval is, the grooves being provided with the serrated portions 5 A to 5 C whose height D is adjusted to a predetermined value according to Formula (2).
