FIELD: medicine.SUBSTANCE: group of inventions refers to medicine. Intraocular lens manufacturing method comprising: an optical characteristics setting step, of setting in an optical portion a spherical aberration of a size, for which the spherical aberration and a coma aberration remaining in a human eye of a patient, from which a human lens was extracted, will not be offset, and of a size corresponding to the coma; a lens shape setting step of determining a lens shape of the optical portion, wherein the spherical aberration set at the optical characteristics setting step is provided as a corrective optical characteristic for a residual irregular astigmatism in that human eye of that patient; and the step on which an intraocular lens is formed, having optical characteristics in which a high-order aberration of that optical portion is rotationally symmetrical around an optical axis, by means of forming the optical portion to have the lens shape determined by the lens shape setting step, wherein the coma represents as a value selected from a group, consisting of: quadratic mean value; the value determined based on the corneal topography measurement values, obtained using a keratometer, a reflex keratometer, or a wave surface sensor; and the values, expressed as a synthetic vector volume of the horizontal coma aberration and the vertical coma aberration, which are represented as C and C terms with Zernike polynomials obtained by performing wave aberration analysis.EFFECT: using said group of inventions ensures to increase an efficiency of vision improvement.8 cl, 6 dwg |
