2. Способ изготовления эластичных искусственных хрусталиков глаза, заключающийся в том, что в литьевую форму, состоящую из двух половинок и выполненную из оптически прозрачного материала, заливают жидкий фотоотверждаемый материал, герметично соединяют половинки литьевой формы с обеспечением с помощью жесткой прокладки строго фиксированного щелевого зазора между ними и облучают УФ-светом, отличающийся тем, что половинки литьевой формы выполнены в виде цилиндров с оптически полированными торцевыми поверхностями, на внутренних поверхностях которых в центральной части имеются углубления, которые при соединении двух половинок литьевой формы образуют оптическую часть хрусталика, при этом на внутренней поверхности одной половинки формы выполнен рисунок, содержащий как прозрачные, так и непрозрачные для УФ-света участки, негативное изображение которого соответствует плоскому изображению оптической части хрусталика и его опорных элементов, на внутренней поверхности другой половинки формы выполнен рисунок, негативное изображение которого соответствует изображению только оптической части хрусталика, а облучение формы проводят в две стадии: первоначально свет фокусируют в центре формы и далее с равномерной скоростью, не превышающей скорости отверждения композиции, увеличивают радиус освещаемой площади до величины, равной радиусу оптической части хрусталика, затем форму облучают по всей поверхности от источника света, обеспечивающего равномерную освещенность всей поверхности формы, и дополнительно включает стадию проявления,состоящую в удалении неотвержденного фотоотверждаемого материала с той внутренней поверхности формы, где сформирован хрусталик, путем растворения в подходящем растворителе, и отжига, состоящей в дополнительном облучении хрусталика, помещенного в бидистиллированную воду с температурой 40-60 oC, УФ-д светом в течение 3-10 мин.1.

2. A method of manufacturing elastic artificial lens of the eye, which consists in pouring a liquid photocurable material into the injection mold, which consists of two halves and is made of an optically transparent material, tightly connect the halves of the mold to ensure a rigidly fixed slit gap between them they are irradiated with UV light, characterized in that the halves of the mold are made in the form of cylinders with optically polished end surfaces on the inner surfaces Stacks in which there are depressions in the central part, which when the two halves of the mold form join, form the optical part of the crystalline lens, while on the inner surface of one half of the mold there is a pattern containing both transparent and non-opaque to UV light areas, the negative image of which corresponds to a flat image the optical part of the lens and its supporting elements, on the inner surface of the other half of the shape, a picture is made, the negative image of which corresponds to the image to the optical part of the lens, and the irradiation of the form is carried out in two stages: initially light is focused in the center of the form and then with a uniform speed not exceeding the speed of curing of the composition, the radius of the illuminated area is increased to a value equal to the radius of the optical part of the lens, then the form is irradiated over the entire surface from a light source that provides uniform illumination of the entire surface of the form, and additionally includes a manifestation stage consisting in removing uncured photocurable material with that the friction surface shape where the lens is formed by dissolving in a suitable solvent, and annealing consisting in additional irradiation lens placed in bidistilled water at 40-60 o C, UV light etc. for 3-10 min.
