Abstract

FIELD: medicine, ophthalmology. SUBSTANCE: method of varying focal power of artificial lens involves periodical compression of an artificial lens end-face portion. The artificial lens is characterized in that the lens is provided with a support ring and a circular groove formed on its end-face surface, the support ring being made of shape memory material. EFFECT: enhanced efficiency. 4 cl, 5 dwg

Description

Изобретение относится к медицине/ к офтальмологии и может быть использовано для временного увеличения остроты зрения. The invention relates to medicine / ophthalmology and can be used to temporarily increase visual acuity.

Известен способ измерения оптической силы линзы при введении искусственного хрусталика в глаз. A known method of measuring the optical power of the lens with the introduction of an artificial lens in the eye.

Известен и искусственный хрусталик/ содержащий линзу и опорное кольцо/ расположенное на теле линзы. Known and artificial lens / containing a lens and a support ring / located on the body of the lens.

Недостатком известных технических решений является то/ что остротой зрения невозможно управлять после внедрения в глаз искусственного хрусталика. A disadvantage of the known technical solutions is that visual acuity cannot be controlled after the introduction of an artificial lens into the eye.

Целью изобретения является упрощение при одновременном обеспечении временного изменения оптической силы линзы. The aim of the invention is to simplify while providing a temporary change in the optical power of the lens.

Сущность изобретения заключается в следующем. При необходимости увеличения дальнозоркости изменяют фокусное расстояние искусственного хрусталика, сдавливая тело хрусталика радиальными усилиями. The invention consists in the following. If necessary, increase farsightedness change the focal length of the artificial lens, squeezing the body of the lens with radial forces.

Для возвращения фокусного расстояния в исходное положение/ убирают радиальные усилия. To return the focal length to its original position / remove radial forces.

Радиальные усилия возникают при сжатии кольца/ размещенного на теле хрусталика. Кольцо выполнено из материала/ обладающего обратимой памятью формы/ например NI-TI, Cu-Al-Zn. Перед установкой на хрусталик кольцо подвергают предварительной термической обработке - закалке в сжатом положении в состоянии высокотемпературной фазы и деформации в разжатое положение в состоянии низкотемпературного мартенситного превращения. Radial forces occur during compression of the ring / lens placed on the body. The ring is made of a material / having a reversible shape memory / for example NI-TI, Cu-Al-Zn. Before installation on the lens, the ring is subjected to preliminary heat treatment — quenching in a compressed position in the state of the high-temperature phase and deformation in the expanded position in the state of low-temperature martensitic transformation.

На фиг. 1 изображен хрусталик в исходном положении/ разрез; на фиг. 2 - хрусталик в сжатом положении/ разрез; на фиг. 3 - кольцо/ вид сверху; на фиг. 4 - схема работы хрусталика в глазе; на фиг. 5 - кольцо <-образной формы/ разрез. In FIG. 1 shows the lens in the initial position / incision; in FIG. 2 - the lens in a compressed position / incision; in FIG. 3 - ring / top view; in FIG. 4 is a diagram of the lens in the eye; in FIG. 5 - ring <-shaped / section.

Пример выполнения способа. An example of the method.

Для временного увеличения дальнозоркости производят нагрев кольца/ в результате тело хрусталика деформируется (сжимается) и изменяется его фокусное расстояние. To temporarily increase farsightedness, the ring is heated / as a result, the body of the lens is deformed (compressed) and its focal length changes.

Нагрев кольца осуществляют/ например/ размещением перед глазами нагретого тела с температурой выше нормальной человеческого тела (36/6оС)/ которое через нагретый окружающий воздух нагреет глаз или временным поднятием температуры тела человека/ например до 37оС/ или подачей в маску теплого воздуха. Для возвращения фокусного расстояния в исходное положение убирают источник тепла и т.д.The heating rings carry / instance / location before the eyes of a heated body with a temperature above normal human body (36/6 C) / through which the heated ambient air will heat the eye or temporary lifting of the body temperature / eg to 37 ° C. / or fed to the warm mask air. To return the focal length to its original position, remove the heat source, etc.

Устройство содержит искусственный хрусталик 1/ на теле котого размещено кольцо 2 из материала с обратимой памятью формы/ имеющее как минимум три внутренних шипа 3 и опорные элементы 4. The device contains an artificial lens 1 / on the body of which is placed a ring 2 of material with a reversible shape memory / having at least three internal spikes 3 and supporting elements 4.

Устройство работает следующим образом. Нагреваясь/ кольцо 2 сжимается и сжимает упругое тело искусственного хрусталика 1/ изменяя его фокусное расстояние/ следовательно/ увеличивая дальнозоркость. Шипы 3 предохраняют кольцо 2 от соскакивания с тела хрусталика 1. Опорые элементы 4 удерживают хрусталик в глазу. The device operates as follows. When heated / the ring 2 contracts and compresses the elastic body of the artificial lens 1 / changing its focal length / hence / increasing farsightedness. The spikes 3 prevent the ring 2 from slipping off the body of the lens 1. The supporting elements 4 hold the lens in the eye.

Для предотвращения выскакивания кольца 2 на теле хрусталика выполнена кольцевая канавка или само кольцо имеет <-образную форму/ тем самым охватывая тело хрусталика. To prevent the ring 2 from popping up, an annular groove is made on the lens body or the ring itself is <-shaped / thereby covering the lens body.
