Abstract

An artificial eye crystalline lens (1) comprises a lens (2) and support elements (3) consisting of shaped rods evenly spaced along the perimeter of the lens and secured to it in a cantilever manner. Each said rod has a proximal end section (5) radially oriented and secured to the lens, and a distal end section (6), connected to the proximal end section through an intermediate section (7) and also oriented in a radial direction, so that the proximal and distal ends (5, 6) are mutually offset in angular direction along the lateral side of the lens thus essentially facilitating the operation and subsequent rehabilitation. A lens construction with folding support elements is also provided.

Area of technology

The present invention is related to the medina, and more precisely, to phthalmology, and specifically, to the articular lenses of the eye.

PREVIOUS LEVEL OF TECHNOLOGY

The last years of widespread expansions were obtained by the artificial eyes, which are installed in the eye of a patient together with a distant, rescued patient.

The implantation of such an artificially acute lesion is.

35 is a common practice after deleting a machine Originally, as shown in FIG. 4, one of the optional elements 3 in the direction of the front or rear is introduced into the catalytic manual or non-selective section - 7 - The cameras of the eye are subject to the proposed scope of fixation. Then, through the lens, lens 2 of the artificially accelerated lens is found to be suitable for the incidence of side lumens 5 at a time with the maximum end points of the element.

The intermediate section or step 13 is made with a pyrotechnic approaching the side of the lens with the second major part of the lens. End section 12. The main section has a simple cross-section, as shown in FIG. 7. The primary 35 end section II has only a linear end contact with a side angle of the lens 9, as this is clearly visible in FIG. 8, and is made of an elastic material, for example, silicone, therefore, to lose the condition, is shared - 8 - as the material, both the size and the size of the device are selected, the lesser force of the external tension of the fluid is selected. In this case, for silicone, there are 5 cases with a common center in the center of the lenses, which are recorded for distant people who are not involved. With such an efficient execution of the external elements 10 they will be folded when wet and

10 Regular fluidity, and the entire artifact has a size corresponding to the size of the lens 9.

Implantation of intensive visualization, shown in FIG. 5 and 6, are as follows. As usual, delete the machine using the extract-

15 laryngeal extraction. After this, the artifical lens of the eye 8 is grasped with 9 pins and moistened with irrigation liquid in the air. The increased tension of the irrigation fluid is greater than the power of the absorber of the artifacts of the large-scale, and the latter is of great importance.

20 elements 10 fold up and fall onto the optical part or lens 9, as in FIG. 9. After this, the artifact of 8 let the eyes inside. With this, the contact of the layer with the irregular liquid on the artificial eye with the air is intensified, the force is reversed.

25 tension relieves its action and powerful elements 10 are self-reliant at the expense of their own devices.
