Problems solved by technology

[0006] The variable focus intraocular lens of the above design is made of silicone material with soft material and low refractive index
Due to the low refractive index of the silicone material, the resulting lens is thicker and the distance the lens moves in the eye's capsular bag is limited, making it possible to focus with limited changes in optical power

Embodiment Construction

[0027] The present invention will be further described below with reference to the drawings and embodiments.

[0028] Fig. 1 is a schematic diagram of a dynamic zoom intraocular lens structure of the present invention.

[0029] Please refer to FIG. 1, the dynamic zoom intraocular lens provided by the present invention includes a central transparent light guide area 1 and a supporting arm 3; wherein a flexible telescopic area 2 is provided between the central transparent light guide area 1 and the supporting arm 3. The front and rear ends of the flexible telescoping area 2 may be provided with limiting protrusions 5.

[0030] The dynamic zoom intraocular lens provided by the present invention is placed in the intraocular capsule during the transplantation process. Under the support of the supporting arm 3, the central transparent light guide area 1 is located in the center of the eye. When the muscle is compressed and relaxed, the lens The central transparent light guide area 1 moves...

Abstract

The invention discloses a dynamic zooming artificial lens and a preparation method of the dynamic zooming artificial lens. The artificial lens comprises a center transparent light guide region and a support arm, wherein a flexible telescopic region is arranged between the center transparent light guide region and the support arm, and the front end and the back end of the flexible telescopic region are provided with position limiting bulges. The dynamic zooming artificial lens and the preparation method of the dynamic zooming artificial lens provided by the invention have the characteristics of softness, high refractive index and thin crystal. Greater forward and back moving distance can be provided in the eyes of the human bodies, so greater optical intensity change can be provided, and the batter dynamic zooming is realized.

Description

Technical field [0001] The invention relates to a hydrophobic polyacrylate intraocular lens and a preparation method thereof, in particular to a dynamically variable zoom hydrophobic polyacrylate intraocular lens and a preparation method thereof. Background technique [0002] The natural lens in the human eye is a colorless, transparent and very soft lens when a baby is born. With age, external conditions change, such as ultraviolet radiation and other factors, the natural lens will change It becomes harder and harder and becomes a colored lens. When people live over the age of fifty to sixty, about 30% of the people’s intraocular lens will turn brown and cloudy, so that they are completely invisible. When this happens, the natural lens (ie, cataract lens) will have to be replaced with an artificial lens to restore the eyesight of cataract patients. [0003] A typical intraocular lens is composed of an optical lens and a supporting arm. The optical lens focuses light on the optic ...
