Abstract
Provided is a technique which, in the design of intraocular lenses, simplifies design work and makes it possible for aberration of the entire eyeball to more precisely match a target value when the designed intraocular lens is inserted into a patient's eye. This intraocular lens design method involves deriving an intraocular lens aberration target value from the aberration of the cornea and anterior chamber and a set value of the total eyeball aberration (S102), and determining an intraocular lens shape such that the at least the aberration of the intraocular lens coincides with the target value (S103-S107). The intraocular lens aberration is set to an intraocular lens aberration for which prescribed convergent light is incident to the intraocular lens (S104).
