Abstract

Изобретение относитс  к офтальмологии и может быть использовано при афакии. Цель изобретени  - уменьшение послеоперационных осложнений. Искусственный хрусталик глаза содержит линзу 1 и опорный элемент 2 с прорез ми 3 по периферии. Опорный элемент имеет три сквозных выреза 4,5, занимающих в тангенциальном направлении сектор с углом раствора 25-30°, а в радиальном направлении промежуток, ограниченный радиусом линзы и радиусом опорного элемента. Опорный элемент  вл етс  продолжением линзы, а радиус кривизны его соответствует среднему радиусу кривизны задней капсулы естественного хрусталика и составл ет 6 мм. Линза занимает центральное положение по отношению к опорному элементу и выполнена в виде мениска, а радиусы кривизны опорного и оптического элемента противоположны по знаку. 1 з.п. ф-лы, 2 ил.The invention relates to ophthalmology and can be used in aphakia. The purpose of the invention is to reduce postoperative complications. The artificial eye lens contains a lens 1 and a support element 2 with slots 3 along the periphery. The support element has three through-cutouts 4.5, occupying in the tangential direction a sector with an angle of 25-30 °, and in the radial direction a gap bounded by the radius of the lens and the radius of the support element. The supporting element is an extension of the lens, and its radius of curvature corresponds to the average radius of curvature of the posterior capsule of the natural lens and is 6 mm. The lens occupies a central position with respect to the support element and is made in the form of a meniscus, and the radii of curvature of the reference and optical elements are opposite in sign. 1 hp f-ly, 2 ill.

Формула изобретенияClaim 1. Искусственный хрусталик глаза, содержащий монолитно выполненные оптический и опорный элементы с вырезом по вертикали и прорезями по периферии, отличающийся тем, что, с целью уменьшения послеоперационных осложнений, знаки радиусов кривизны опорного и оптического элементов противоположны, оптический элемент выполнен в виде мениска, причем радиус кривизны опорного элемента равен среднему радиусу кривизны задней капсулы хрусталика.1. The artificial lens of the eye, containing integral optical and support elements with a vertical cut and cuts along the periphery, characterized in that, in order to reduce postoperative complications, the signs of the radii of curvature of the support and optical elements are opposite, the optical element is made in the form of a meniscus, the radius of curvature of the support element is equal to the average radius of curvature of the posterior lens capsule. 2. Искусственный хрусталик глаза по π. 1, отличающийся тем, что, с целью умень- шения операционных осложнении, на опорном элементе выполнены дополнительные вырезы с размером в 25—30 угловых гра дусов, расположенные симметрично относи тельно вертикальной оси оптического эле мента.2. Artificial lens of the eye according to π. 1, characterized in that, in order to reduce operational complications, additional cutouts with a size of 25-30 angular degrees located symmetrically relative to the vertical axis of the optical element are made on the support element.
