Изобретение относитс к медицине, а именно к офтальмологии, и может быть использовано дл хирургической коррекции афакии.The invention relates to medicine, namely to ophthalmology, and can be used for the surgical correction of aphakia.
Цель изобретени - уменьшение трав- матичности операции и количества послеоперационных осложнений путем автоматической адаптации к передней камере глаза разного диаметра с сохранением посто нства удельного давлени опорных элементов на структуры угла передней камеры.The purpose of the invention is to reduce the trauma of the operation and the number of postoperative complications by automatically adapting to the anterior chamber of the eye of different diameters while maintaining the constant specific pressure of the supporting elements on the anterior chamber angle structures.
На фиг. 1 и 2 схематично изображен искусственный хрусталик глаза, две проекции; на фиг. 3 - схема размещени искусственного хрусталика в передней камере глаза при различном его диаметре.FIG. 1 and 2 schematically shows an artificial lens of the eye, two projections; in fig. 3 is a diagram of the placement of the artificial lens in the anterior chamber of the eye at a different diameter.
Искусственный хрусталик глаза состоит из оптической линзы 1 и двух пар опорных элементов 2 и 3, симметричных относительно горизонтальной оси линзы. Кажда из пар опорных элементов 2 и 3 выполнена в виде дуг, обращенных вогнутой стороной друг к другу и пересекающихс между собой в точке 4, лежащей на продолжении вертикальной оси оптической линзы 1.The artificial lens of the eye consists of an optical lens 1 and two pairs of supporting elements 2 and 3, symmetrical about the horizontal axis of the lens. Each of the pairs of supporting elements 2 and 3 is made in the form of arcs, with the concave side facing each other and intersecting at the point 4, lying on the extension of the vertical axis of the optical lens 1.
Имплантацию искусственного хрусталика глаза осуществл ют следующим образом .The implantation of an artificial eye lens is carried out as follows.
Акинези 2%-ным раствором новокаина 10,0 мл. Ножом Сато производ т переднюю капсулотомию хрусталика, пинцетом Кел- мана удал ют переднюю капсулу хрусталика . Через роговичный разрез 3 мм ввод т в переднюю камеру наконечник факоэмульси- фикатора, производ т дробление и аспирацию дра и хрусталиковых масс. Разрез продлевают в обе стороны до 6 мм, после чего ввод т в переднюю камеру оптическую линзу 1 и фиксируют опорными элементами 2 и 3 в нижнем и верхнем квадрантахAkinesia 2% solution of novocaine 10.0 ml. The Sato knife is used to make the anterior lens capsulotomy, and the Kelman tweezers remove the anterior lens capsule. Through a corneal incision of 3 mm, the tip of the phacoemulsifier is inserted into the anterior chamber, crushing and aspiration of the nucleus and lens masses are performed. The incision is extended in both directions up to 6 mm, after which the optical lens 1 is inserted into the anterior chamber and fixed by supporting elements 2 and 3 in the lower and upper quadrants
угла передней камеры под гониоскопическим контролем (при необходимости производ т репозицию микрощпателем). На кра разреза накладывают четыре-п ть узловых швов из супрамида 9-0. Под конъюнктиву инъецируют дексазон и цефамизин по 0,3 мл. Накладывают монокул рную пов зку.anterior chamber angle under gonioscopic control (if necessary, reposition with a micro-spreader). On the edges of the incision impose four or five interrupted sutures from supramid 9-0. Under the conjunctiva inject dexazone and cefamisin 0.3 ml. Monocular stitching is applied.
Конструкци искусственного хрусталика позвол ет имплантировать его через минимальный разрез в стенке глаза 6 мм, при этом фиксаци в четырех точках угла передней камеры повыщает стабильность положени линзы в глазу, что позвол ет предупредить ротирование и смещение линзы, уменьшить количество послеоперационных 5 осложнений. В случае использовани искусственного хрусталика при несоответствии размеров линзы и диаметра передней камеры глаза происходит сжатие гибких опорных элементов, при этом увеличиваетс площадь контакта опорных элементов со структурами угла передней камеры, сила давлени их остаетс прежней. Это позвол ет избежать послеоперационных осложнений со стороны внутренних структур глаза.The design of the artificial lens allows implanting it through a minimal incision in the eye wall of 6 mm, while fixing the angle of the anterior chamber at four points increases the stability of the lens in the eye, which prevents the lens from rotating and shifting, reducing the number of postoperative 5 complications. In the case of using an artificial lens when the lens size and diameter of the anterior chamber of the eye do not match, the flexible support elements are compressed, the contact area of the supporting elements with the structures of the anterior chamber angle increases, and the pressure force remains the same. This avoids postoperative complications from the internal structures of the eye.
