Description of the invention (1) (Please read the precautions on the back before filling out this page) The present invention relates to an artificial lens that can be automatically adjusted, especially an artificial lens that can actively adjust its position in the eyeball To change the overall optical power of the eyeball. Field of patent · This patent relates to the artificial lens in the eyeball, especially the artificial lens in the eye that can automatically adjust the dioptric power. Please refer to Annex I for a section of a normal human eyeball. Generally, cataract patients need to install an artificial lens because of the aging of the lens. There are two ways to install it: one is installed in the Posterior capsule bag P, If the posterior capsular bag P is incomplete, it is installed on the Ciliary sulcus C. Most of the current artificial 7ic lenses are fixed power. After being assembled in patients with cataract surgery, the artificial vision is fixed, so the clear vision obtained by the patient is limited to the focal length of the patient's eyeball synthesis power after surgery. If the patient's vision is far-sighted, the near vision is not clear, and the near-distance vision is not clear. This is because the artificial lens cannot look like the lens of a young normal person. It can be adjusted by looking at the distance. The reason. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, please refer to the first picture. The central optics 101 of the conventional traditional artificial crystal 100 are provided with two haptan 102, as shown in the second picture. It is shown that the artificial lens 100 is installed in the capsule bag 200 of the lens; or when the 200 bag is incomplete and placed on the ciliary body groove (Sulcus) 300, as shown in the third figure, The two feet 10 of the artificial crystal lens 100 are hooked to the ciliary body groove 300 respectively. ^ The interior chamber distance (ACD) is fixed before the above situation, and the diopter cannot be adjusted. With the ability to adjust near and far vision, the following various methods have been created: ... Previous techniques ... Many methods have been proposed to address the need for eyeball accommodation after cataract extraction surgery: 1. Implantation of multifocal artificial Crystals, which have many different focal areas on artificial crystals, are in US Pat. No. 4666446, 4710193, this paper size ϋ Chinese National Standard (CNS) Α4 specifications (210X297 public director) '' ~ " 523408 A7 __B7 V. Description of the invention (2) (Please read the precautions on the back before filling out this page) 4759762, 5225858, 5326348, and 5507806 are pre-patent cases. Focus design. This type of design is an eclectic adjustment method. They cannot change the dioptric power as desired, and there will be blurred areas that affect the field of view, and the amount of light will be reduced. 2. Use a small aperture to increase the depth of field. This method is found in US Pat. No.4759762. This method will also greatly reduce the amount of light and lose the field of view. Pre-patent case. 3. It is mainly driven by the ciliary muscle directly or indirectly, such as the pre-patent cases such as US Pat. No. 4842601, 4888012'4892543, 4932966 5476514, 558081, 5604872, 5843188 and 6197059B1; There are still many problems to be solved in the design, the most important of which is the effectiveness and stability of the connection between the lens and the ciliary muscle. 4. Other US patents USPat. No. 6200342Bl is an artificial lens that can be driven by pupillary L (pupil) contraction to change the degree; in US Pat. Nos. 5108429, 5171266, 5203788, and 5800533 are a series of artificial crystals. The diopter adjustment can be performed by a micromotor or an external electromagnetic field, but these are not designed for near-far adjustment, and their structural arrangement is very different from the present invention. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economics The present invention is an artificial crystal, which can be controlled by the user to change its position on the visual axis without the need for contraction of the ciliary muscle. The fixation method in the eyeball is very similar to the fixed focal length artificial lens that is currently widely used. Therefore, the present invention has many advantages compared with the prior art in this field. The reason is that the main object of the present invention is to provide an artificial lens that can be automatically adjusted, and its position in the eyeball can be adjusted at will to achieve the creation of changing the overall optical power of the eyeball, which can keep the artificial lens at a distance. Looking at the best position, when looking at a long distance, the artificial crystal will move one position forward and change linearly. When the user looks at the nearest distance, the artificial crystal will stay at the most paper scale.隼 (CNS) A4 specification (210X297 mm) 523408 A7 B7 V. Description of the invention (3) The position of the front end of the front end; its overall power source is gravity, and the user changes the pitch angle between head-up and head-down The adjustment of the displacement driving force acting on the artificial lens, so as to actively control the position of the artificial lens, and thus enables the user to actively control the distance adjustment degree of the eyeball of the implanted artificial lens. Another purpose of this creation is to provide an artificial 7jC crystal that can be automatically adjusted. When special needs, external magnetic glasses or magnetic control sources use external magnetic fields to adjust the front and rear positions of the lens, thereby changing the refractive power of the eyeball.
