Description

Изобретение относитс  к медицинс кой технике, а именно к офтальмологии , и может быть использовано дл  восстановлени  зрени  после операции по удалени  помутневшего хруста лика (катаракты). , Известен искусственный хрусталик глаза, содержащий линзу и опор ные элементы в виде ножек, концы ко торых загнуты параллельно задней по верхности линзы и выполнены в виде пр моугольных колен l1. Однако крепление такого искусственного хрусталика в глазу влечет за собой изменение формы зрачка, кроме того, возможно смещение опорных ножек при легких толчках, операци  травматична  и сложна. Цель изобретени  -г исключение см тени  линзы и уменьшение травмати-. зации тканей глаза. Поставленна  цель достигаетс  тем, что хрусталик снабжен дополнительным опорным элементом, выполнен ным в виде металлического шипа и ра положенншл между ножками на периферии линзы, при этом последние изогнуты таким образом, что имеют   вер ней части горизонтальные участки. На чертеже изображен искусственный хрусталик глаза в двух проекци х . , Искусственный хрусталик глаза содержит линзу 1, опорные элементы в виде ножек 2, концы которых загнуты параллельно задней поверхности линзы и выполнены в виде пр моугольных колен , при этом ножки в верхней части имеют горизонтальные участки. На периферии линзы 1 между ножками 2 размещен дополнительный опорный элемент в виде металлического шипа. Особенности конструкции опорных ножек искусственного хрустсшика глаза исключают смещение линзы по горизонтали (вправо-влево), при необходимости в месте изгиба можно провести шов, фиксирующий линзу 1 к радужной оболочке. После введени  линзы в глаз, шип 3 внедр етс  в ткань радужной оболочки, дава  тем самым дополнительную точку опоры, гарантирующую от смещени  по вертикали (вверх-вниз). Иногда бывает целесообразно на завершаквдем этапе загнуть указанный шип 3 вверх и тем селилл Плотно фиксировать линзу 1 к радужной о«$о очке (подобно , как это получаетс , при проведении ирис-шва).The invention relates to a medical technique, namely, ophthalmology, and can be used to restore vision after surgery to remove a clouded clasp (cataract). The artificial lens of the eye is known, which contains a lens and supporting elements in the form of legs, the ends of which are bent parallel to the back surface of the lens and made in the form of rectangular elbows l1. However, the attachment of such an artificial lens in the eye entails a change in the shape of the pupil, in addition, it is possible that the supporting legs can be displaced during light shocks, the operation is traumatic and complex. The purpose of the invention is to eliminate the shade of the lens and reduce trauma. eye tissue systems. The goal is achieved by the fact that the lens is provided with an additional supporting element made in the form of a metal spike and located between the legs on the periphery of the lens, while the latter are curved in such a way that they have vertical portions of the horizontal sections. The drawing shows an artificial lens of the eye in two projections. The artificial lens of the eye contains lens 1, supporting elements in the form of legs 2, the ends of which are bent parallel to the back surface of the lens and made in the form of rectangular knees, while the legs in the upper part have horizontal sections. On the periphery of the lens 1 between the legs 2 an additional supporting element in the form of a metal spike is placed. The design features of the support legs of the artificial eye crystal eliminate the horizontal displacement of the lens (right-left); if necessary, a suture can be made at the bend, fixing lens 1 to the iris. After inserting the lens into the eye, spike 3 is inserted into the tissue of the iris, thereby providing an additional point of support, which ensures that it does not move vertically (up and down). Sometimes it is advisable at the completion of the stage to bend the indicated spike 3 upwards and, thus, fix the lens 1 to the rainbow about $ 10 o'clock tightly (similar to how it is obtained when performing an iris seam).

Конструкци  искусственного хрусталика позвол ет значительно упростить технику имплантации при сохранении вс принципиальных достоинств экстрапупилл рной фиксации искусственного хрусталика глаза к радужной оболочке.The design of the artificial lens allows the implantation technique to be greatly simplified, while retaining all the fundamental advantages of extrapupillary fixation of the artificial lens of the eye to the iris.
