Claims (4)

1. Бифокальная объемозамещающая оптическая система, состоящая из основной и дополнительной интраокулярной линзы (ИОЛ) или частей последней, находящейся перед основной оптической частью ИОЛ в параллельной с ней плоскости с частичным ее перекрытием, на одной центральной оптической оси оптической системы для суммирования оптической силы линз в зоне их перекрытия, причем основная ИОЛ содержит два диаметрально расположенных лепестка плоскостных гаптических элементов с областью сгибания, при этом задняя поверхность дистальных концов гаптических элементов основной ИОЛ контактирует с передним листком KMX и длина гаптических элементов превосходит размер заднего листка капсулы хрусталика, а область их сгибания удалена от оптической части линзы и выполнена с возможностью растяжения KMX в экваториальной зоне и в переднезаднем направлении, отличающаяся тем, что оптическая система представлена линзами, имеющими идентичные размеры и параметры гаптических элементов, которые фиксируются в KMX за счет сил их упругой деформации, при этом размер дополнительной линзы превосходит размер переднего листка KMX, а передняя поверхность дистальных концов гаптических элементов дополнительной ИОЛ контактирует с задним листком KMX, при этом линза расположена перпендикулярно к продольной оси симметрии основной линзы, не контактируя с ней.1. Bifocal volume-replacing optical system consisting of the main and additional intraocular lens (IOL) or parts of the latter, located in front of the main optical part of the IOL in a plane parallel to it with partial overlap, on one central optical axis of the optical system to sum the optical power of the lens in the area of their overlap, with the main IOL contains two diametrically located petals of planar haptic elements with a bending area, while the posterior surface of the distal ends of the haptic The main elements of the IOL are in contact with the front sheet of KMX and the length of the haptic elements exceeds the size of the back sheet of the lens capsule, and their flexion area is removed from the optical part of the lens and is designed to stretch the KMX in the equatorial zone and in the anteroposterior direction, in that the optical system is represented lenses having identical dimensions and parameters of haptic elements, which are fixed in KMX due to the forces of their elastic deformation, while the size of the additional lens exceeds the size front sheet KMX, and the front surface of the distal ends of the haptic elements additional IOL in contact with the rear sheet KMX, while the lens is perpendicular to the longitudinal axis of symmetry of the main lens, not in contact with it. 2. Бифокальная оптическая система по п. 1, отличающаяся тем, что параметры жесткости гаптических элементов основной и дополнительной ИОЛ различны.2. Bifocal optical system according to claim 1, characterized in that the stiffness parameters of the haptic elements of the main and additional IOL are different. 3. Бифокальная оптическая система по п. 1, отличающаяся тем, что в области проксимальных концов гаптических элементов основной ИОЛ в точках, соответствующих вершинам квадрата, вписанного в окружность оптической части, имеются технические элементы, которые предназначены для их интраоперационной визуализации с целью лучшей центрации ИОЛ.3. The bifocal optical system according to claim 1, characterized in that in the area of the proximal ends of the haptic elements of the main IOL, at the points corresponding to the vertices of the square inscribed in the circumference of the optical part, there are technical elements that are intended for their intraoperative visualization in order to better center the IOL . 4. Бифокальная оптическая система по п. 1, отличающаяся тем, что дистальные концы гаптических элементов составляющих ИОЛ устройства имеют закругленные вырезы, при этом вырез окружности направлен к центру устройства.4. The bifocal optical system according to claim 1, characterized in that the distal ends of the haptic elements of the components of the IOL device have rounded cuts, while the cutout of the circle is directed towards the center of the device.
