Abstract
Description
Изобретение относится к медицине/ к офтальмологии и может быть использовано для временного изменения рефракции линзы хрусталика. The invention relates to medicine / ophthalmology and can be used to temporarily change the refraction of the lens of the lens.
Известен способ и устройство увеличения рефракции оптической системы глаза/ включающий введение в глаз искусственного хрусталика/ состоящего из линзы и опорных элементов. A known method and device for increasing refraction of the optical system of the eye / including the introduction into the eye of an artificial lens / consisting of a lens and support elements.
Известна также внутриглазная линза регулируемая лазером и метод изменения силы линзы/ включающий изменение формы линзы прямым воздействием лазером. Also known is an intraocular lens adjustable by a laser and a method of changing the strength of the lens / including changing the shape of the lens by direct exposure to a laser.
Недостатком прототипа является сложность метода и необратимость рефракции. The disadvantage of the prototype is the complexity of the method and the irreversibility of refraction.
Целью изобретения является упрощение при одновременном обеспечении временного изменения рефракции. The aim of the invention is to simplify while providing a temporary change in refraction.
Поставленная цель достигается тем/ что перемещают оптический элемент хрусталика вдоль оптической оси глаза/ а опорная часть хрусталика - кольцо/ снабжено дужками/ ступенчато изогнутыми в плоскости/ перпендикулярной главной плоскости оптического элемента и изогнутыми одна навстречу другой/ свободные концы дужек симметрично расположены относительно точки крепления их и параллельны главной плоскости оптического элемента/ при этом опорная часть выполнена из материала/ обладающего памятью формы. This goal is achieved by the fact that the optical element of the lens is moved along the optical axis of the eye / and the supporting part of the lens is a ring / is equipped with arches / stepwise curved in the plane / perpendicular to the main plane of the optical element and curved one towards the other / the free ends of the arches are symmetrically located relative to their attachment point and parallel to the main plane of the optical element / while the supporting part is made of material / having a shape memory.
Сущность изобретения заключается в следующем. Изменение рефракции осуществляют микроперемещением искусственного хрусталика при сжатии или разжатии опорных элементов/ выплавленных из материала с памятью формы/ например NITI/ и предварительно термообработанных. На фиг. 1 показан искусственный хрусталик с сжатым опорным элементом; на фиг. 2 - искусственный хрусталик с выпрямленным опорным элементом; на фиг. 3 - искусственный хрусталик/ вид сверху; на фиг. 4 - схема микроперемещения искусственного хрусталика в глазе. The invention consists in the following. The change in refraction is carried out by micro-movement of the artificial lens during compression or decompression of the support elements / melted from a shape memory material (for example, NITI) and previously heat-treated. In FIG. 1 shows an artificial lens with a compressed support element; in FIG. 2 - artificial lens with a straightened support element; in FIG. 3 - artificial lens / top view; in FIG. 4 is a micro-movement diagram of an artificial lens in the eye.
Устройство содержит искусственный хрусталик 1/ на теле которого размещено кольцо 2 с дужками 3/ выполненными из материала с памятью формы/ т. е. с обратимым мартенситным превращением. The device contains an
Для выполнения способа осуществляют нагрев опорного элемента/ например повышением температуры обдуваемого воздуха (в маске) или его охлаждением. To perform the method, the support element is heated / for example, by increasing the temperature of the blown air (in the mask) or by cooling it.
Устройство работает следующим образом. The device operates as follows.
Нагреваясь или охлаждаясь/ дужки 3 кольца 2 перемещают искусственный хрусталик 1/ изменяя тем самым рефракцию оптической системы глаза. By heating or cooling / the
