Abstract

An artificial intraocular lens for use in ophthalmology to correct ametropia comprises: an optical component (1), support elements (2) and shaped channels (3) for securing the support elements (2), said channels being formed by two intercommunicating apertures (4 and 5). The aperture (4) opens out onto the optical component, while the aperture (5) opens out onto the lateral surface (6) of the lens and in cross section has an elongated shape which follows the main surface of the lens. The section (7) of the support element (2) situated in the aperture (5) is identical in cross section to the cross section of the aperture (5). The aperture (4) in the region of the connection with aperture (5) has a cross-sectional area equal to or greater than that of aperture (5). This makes it possible to mount the support elements (2) securely in the channel (3) while reducing the thickness of the optical component of the lens.

With such a cost-effective implementation of the physical channels

20 The reliability of the storage of external elements in the optical part of the lens is ensured.

The only use of threaded nodes in such an artifact is that they have a sharp eye made from an optical lens that is not very clean.

35 It leads to a decrease in the thickness of the walls between the channel and the optical lenses and to an increase in the acoustics of these particles. Reducing the diameter of an element is possible only to selectively divide it, since it reduces its elastic properties and weakens hardness. - 2 - accumulation of temperature in the eye capsule. Β In connection with this, in the case of a round format, restrictions are imposed on the maximum thickness of the disc and the possibility of reducing its weight, which should be avoided.
