摘要:
1. A wide-angle optical device for ophthalmic eye implants, having a lens system (2) located symmetrically around the optical axis (5), comprising at least two lenses (8-12) located in the same plane from one another with materials of different optical refractive indices, as well as a trailing lens located proximal to the inner part of the eye and worn around the optical separation structure. 2. The device according to claim 1, characterized in that there is an additional combination (3) of lenses and / or lens elements with adjustable focal length, made with the possibility of mechanical movement. The device according to claim 2, characterized in that the closure lens (4) located proximal to the inner part of the eye and / or with the possibility of movement, the combination (3) of lenses and / or lens elements with adjustable focal length has a surrounding ring-shaped bordering surface, and on it wearing optical separation structure (6) .4. A device according to claim 1, characterized in that the optical dividing structure (6) has a non-constant cross-section of the structure along the periphery. The device according to claim 1, characterized in that the separation structure (6) consists of ring segments that completely or partially overlap the total covering the bordering surface. A device according to claim 1, characterized in that the dividing structure (6) is formed by at least a circular prism and / or segments of a circular prism. The device according to any one of paragraphs. 1-6, characterized in that the lens located proximal to the inner part of the eye, as well as the separation structure (6), have a different refractive index.1. Широкоугольное оптическое устройство для офтальмологических имплантатов глаза, имеющее расположенную симметрично вокруг оптической оси (5) систему (2) линз, содержащую, по меньшей мере, две расположенные в одной плоскости одна за другой линзы (8-12) из материалов с различными оптическими коэффициентами преломления, а также замы
