FIELD: medicine.SUBSTANCE: group of inventions relates to medicine. An accommodating intraocular lens (AIOL), is adapted for implantation into the posterior eye chamber, contains an optic element, which contains two optic zones with similar optic power and is made with a possibility to create a trapezoid phase shift, with the said trapezoid phase shift being a linear change between two optic zones in a phase shift, transmitted to input light as a radius function; a multitude of haptic elements, with each haptic element passing from the connection of a haptic element with the optic element to, at least, one transverse arc, made with a possibility of contact with the capsular sac of the eye in implantation, and each haptic element has a sufficient length and rigidity for stretching the capsular sac of the eye for a contact with the ciliary muscles of the eye; in which connections of the haptic element with the optic element are made with a possibility to bend the optic element in a forward direction relative to the haptic elements, so that the compression of the haptic elements by the ciliary muscles renders on the optic elements a forward-directed effort with a value of, at least, 1.5 mN, with the trapezoid phase shift providing the enhancement of the visual effect of the forward-directed effort to provide at least a 0.75 dpt change of the total acting power.EFFECT: application of the claimed group of inventions will make it possible to extend the arsenal of technical means.16 cl, 6 dwg |
