Description

Изобретение относится к медицине, в частности к офтальмологии, и предназначено для имплантации в глаз вместо удаленного хрусталика.The invention relates to medicine, in particular to ophthalmology, and is intended for implantation in the eye instead of the remote lens.

Цель изобретения - повышение комфортности зрения.The purpose of the invention is to increase the comfort of vision.

На фиг.1 показан искусственный хрусталик в двух проекциях; на фиг. 2 - механизм изменения кривизны передней поверхности оптической камеры.Figure 1 shows an artificial lens in two projections; in FIG. 2 - mechanism for changing the curvature of the front surface of the optical camera.

Искусственный хрусталик состоит из двух камер 1 и 2, сообщающихся через отверстие 3. Передняя стенка (мембрана) 4 камеры 1 (оптической камеры) выполнена из прозрачного эластического материала, например, силиконовой резины. Задняя стенка камеры 1 представлена собирающей линзой 5. Задняя стенка.камеры 2 представляет собой эластическую мембрану 6, к которой зафиксирован магнит 7. Обе камеры 1 и 2 заполнены жидкостью с показателем преломления выше показателя преломления внутриглазной жидкости (1. 336). Жидкость может перемещаться из одной камеры в другую через отверстие 3. Опорные элементы искусственного хрусталика - полупетля 8 и корпус камеры 2. Вне глаза размещается блок М, способный регулировать магнитное поле в области переднего отрезка глаза. '«The artificial lens consists of two chambers 1 and 2, communicating through the opening 3. The front wall (membrane) 4 of the camera 1 (optical camera) is made of transparent elastic material, for example, silicone rubber. The rear wall of the chamber 1 is represented by a collecting lens 5. The rear wall of the chamber 2 is an elastic membrane 6 to which a magnet 7 is fixed. Both chambers 1 and 2 are filled with a liquid with a refractive index higher than the refractive index of the intraocular fluid (1. 336). The fluid can move from one camera to another through the opening 3. The supporting elements of the artificial lens are half loop 8 and the camera body 2. Outside the eye, a block M is placed that can adjust the magnetic field in the region of the anterior segment of the eye. '"

Работа искусственного хрусталика осуществляется следующим образом. Искусственный хрусталик имплантируется в глаз вместо удаленного мутного хрусталика. Остатки капсулы удаленного хрусталика 9 используются для фиксации опорных элементов искусственного хрусталика. Блок М, размещенный вне глаза, позволяет регулировать магнитное поле в области переднего отдела глаза. В том случае, если магнитное поле отсутствует или представлено слабыми значениями, эластическая мембрана 6 имеет вид плоскости (см. фиг.2). Когда же блок М создает магнитное поле вThe work of the artificial lens is as follows. An artificial lens is implanted in the eye instead of a distant, cloudy lens. The remnants of the capsule of the remote lens 9 are used to fix the supporting elements of the artificial lens. Block M, located outside the eye, allows you to adjust the magnetic field in the anterior region of the eye. In the event that the magnetic field is absent or is represented by weak values, the elastic membrane 6 has the form of a plane (see figure 2). When does block M create a magnetic field in

=1810052 А области переднего отрезка глазного яблока, магнит 7 смещается внутрь камеры 2. увлекая за собой эластичную мембрану б. При этом объем камеры 2 уменьшается, а жидкость из камеры 2 через отверстие 3 перемещается в камеру 1. Вследствие повышения давления в камере 1 ее передняя эластическая стенка 4 выпячивается кпереди. Радиус.ее кривизны уменьшается, а оптическая сила возрастает.= 1810052 And the area of the anterior segment of the eyeball, the magnet 7 is shifted into the interior of the chamber 2. entraining the elastic membrane b. The volume of the chamber 2 decreases, and the liquid from the chamber 2 through the hole 3 moves into the chamber 1. Due to the increase in pressure in the chamber 1, its front elastic wall 4 is protruded anteriorly. The radius of its curvature decreases, and the optical power increases.

При зрении вблизи конструктивные элементы искусственного хрусталика находятся во взаимоотношении, показанном на фиг.1; при зрении вблизи, когда необходимо усиление преломляющей силы, элементы искусственного хрусталика принимают позицию, показанную на фиг.2.With near vision, the structural elements of the artificial lens are in the relationship shown in figure 1; when near vision, when it is necessary to strengthen the refractive power, the elements of the artificial lens take the position shown in figure 2.

Предлагаемое* устройство относится к новому поколению искусственных хрусталиков, позволяющих иметь человеческому ' глазу четкое зрение на различные расстояния. Фактически речь идет об аккомодирующем искусственном хрусталике. Внедрение предлагаемого искусственного хрусталика в практику позволит получить ‘ большое преимущество по меньшей мере в двух отношениях: во-первых, человек с аккомодирующим искусственным хрусталиком обладает ясным зрением на различные расстояния, что увеличивает работоспособ- ! ность зрительного анализатора и исключает необходимость пользоваться дополнительной коррекцией. Разница между аккомоди10The proposed * device refers to a new generation of artificial lenses that allow the human eye to have clear vision at various distances. In fact, we are talking about an accommodating artificial lens. Putting the proposed artificial lens into practice will allow you to get ‘a great advantage in at least two respects: firstly, a person with an accommodating artificial lens has clear vision at various distances, which increases working capacity! visual analyzer and eliminates the need to use additional correction. The difference between accommodation10

i ' рующим и неаккомодирующим искусственными хрусталиками такая же, как разница между глазом молодого человека и старика, во-вторых, расчет оптической силы искусственного хрусталика неизбежно сопряжен с погрешностью, поэтому в глазах с искусственным хрусталиком примерно в полоаине случаев имеет место аномалии рефракции, что выну^кдает человека пользоваться очками. Регулируемая преломляющая сила аккомодирующего хрусталика позволяет коррегировать погрешности расчета и исключает необходимость пользоваться дополнительно коррелирующими очками.i 'ning and non-accommodating artificial lenses are the same as the difference between the eye of a young man and an old man, secondly, the calculation of the optical power of an artificial lens is inevitably associated with an error, therefore, in the eyes with an artificial lens in about half the cases there are refraction anomalies that ^ asks a person to use glasses. Adjustable refractive power of the accommodating lens allows you to correct the calculation errors and eliminates the need to use additional correlating glasses.
