In the mid-1990s, plate crystals were introduced, which included a length of 1 〇:2: enamel resin crystals with a 6 mm optical section. These crystals can be folded: they cannot be fixed in the pouch and remain in the garment between the anterior and posterior capsules. The original collapsible crystals were all made of silicone resin. In the mid-1990s, an acrylic material was introduced as the optical department of the crystal. Acrylic crystals comprise a biconvex optic having a right-angled edge into which the loop is inserted to center the crystal in the eye and secure it within the pocket. Recently, pericardial artificial crystals have been introduced to the market, which are usually improved plate haptic lenses. The plate contact crystal can be referred to as an artificial crystal having two or more of the adhesion plates bonded to the optical portion. Flexible acrylic materials have gained significant popularity among ophthalmic surgeons, however some acrylic materials cannot be flexed multiple times without breaking. In 2003, more than 50% of implanted artificial crystals had an acrylic optics. Flexible hydrogels and collamer crystals have also been introduced. Regulatory water 6 that acts by repeatedly flexing along the axis of the eye; 2008: The body: the advent of the material that can be used to make crystals is somewhat limited. The resin is flexible and can be bent for hundreds of times. Ten thousand times, any damage is revealed, so it is the ideal material. —T- “Shoulder 1 or: Φ is part of the design of the crystal and placed across the adjacent photons...plates to promote the movement of the optics relative to the end of the clad plate. [Invention] Wan Moxibustion Zhao Ben invention claims to apply on March 13, 2007: /m, 631 application priority. The disclosure of this application is incorporated herein by reference: a preferred embodiment of the present invention. In an example, an accommodating crystal lens comprises a crystal having one flexible solid optical portion, and two or more expanded portions are attached to the optical portion. The optical portion may be a double convex surface, a multi-sphere: Aspherical or have a surface (hsnell surfaee). Expansion: part, adhesion, can be a plate or ring of Figure 4, mesh 5 and Figure 6, /, can be open or closed, each board The piece or loop can be flexed multiple times without breaking. The cleat preferably has a fixed and centered (* ntratl〇n) feature at its distal end. The expanded portion is designed to contract the ciliary muscle, When the associated vitreous cavity pressure increases, the extension is prevented from being in the week. The edge moves outward. This may be accompanied by a narrower distal end than the proximal end, or an expanded portion having parallel sides. The wider adhesive member cannot be moved into the smaller pocket formed by the fusion anterior capsule and the capsule. Therefore, it is possible to prevent the adhesive member from moving around the center of the iliac crest muscle when the contraction of the ciliary muscle is contracted, and the pressure of the vitreous chamber is further increased. The span of the optical portion adjacent to the 7 200843706 is further extended. The recording member or the groove is stretched by the elastic base of the hinge with the contraction of the ciliary muscle and the force of the glass shark to facilitate the movement of the optical portion with respect to the front and rear portions of the both ends of the expanded portion. In addition, the light is moved to move forward in front of the outer end of the member by sharpening the angle between the crystal optical portion and the adhesive member. Conversely, the adhesive sheet may have a narrow proximal end or a parallel side. 〃, 睫 睫 睫 睫 睫 及 及 及 及 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫 睫Can be made The shape of the optics is changed, Μ ^ ^ and Ai 攸 increases the movement of the optics and increases the force of the eye refraction. This can be reduced by the optical portion or by the thickness of the center of the optic with its radius of curvature. Therefore, the change of the regulatory ability of the regulatory I〇L during ciliary muscle contraction can be a combination of four factors. The image is the movement of the entire front of the crystal in the human lens. b) The optics The movement of the optical portion relative to the outer end of the adhesive member caused by the change in the angle between the adhesive members. The elastic base of the joint member is stretched to cause the optical portion to be opposed to the outer end and the inner end of the adhesive member. Part movement d. Deformation of the optical part of the thin hydrocrystal. Various mechanisms can work alone or in combination, and mainly depend on the design of photons, p and the components. The adhesive member can be a plate or loop design' and the loop can be open or closed. It is preferably designed as a plate. 8 200843706 Since the periphery of the pocket formed between the capsule and the posterior capsule before fusion is narrow and too small to allow the wider plate to move into the periphery, when the ciliary muscle contracts and thus the vitreous cavity pressure increases, there is proximity to the optics. The hinged wide proximal plate design cannot move around. As the ciliary muscle contracts, the plate of the design moves in the center, and since the crystal of the eye is arched at the back, the proximal end of the plate also moves at the rear, further increasing the pressure of the vitreous cavity. The thin hinge base is then stretched causing the optic to move forwardly relative to both the outer and inner ends of the panel. Accordingly, the features of the present invention provide improved forms of modulating crystals. [Embodiment] Referring now to the drawings, FIG. 1 to FIG. 3 illustrate in detail a preferred example including an artificial crystal lens 1, which is formed into a flexible solid optical portion 2 preferably made of Shishi resin. It has 360. a rear right-angled edge; and a flexible extension 4, which may be any suitable form, but preferably a triangular plate-type adhesive member having a wide base adjacent the optical portion, which can be flexed multiple times There is no damage and it is formed, for example, from a enamel resin. The optical portion 2 and the adhesive member 4 are preferably in the same plane until they are implanted in the eye, and the two adhesive members 4 extend distally from opposite sides of the optical portion 2. A fixing and centering finger 6 is provided at the distal end of the hinged adhesive member 4. The typical length of the crystal is 10.0-12.0 mm, and the optics 2 is typically an optical portion of 4.5-6.0 mm diameter. The finger 6 is preferably about 5. The melon is wide and contains a four-point fixed loop. The tip 8 has a slightly different configuration and helps to position the hinge in the proper position to indicate that the correct side of the surgeon's crystal system is facing up. 9 200843706 It is desirable that the clinging member 4 has a triangular shape that is wider at the adjacent optical portion and narrower at the outer end. In the outer periphery of the adhesive member 4 and the optical portion 2, there is again a joint 1 〇, and it is particularly desirable that the hinge has a wide elastic base j 12 to allow the optical portion 2 to be pedestal due to the thin and wide hinge base , as the pressure in the vitreous cavity increases, the longitudinal axis of the crystal extends and moves forward. The wide hinge base of the longitudinal axis of the crystal allows for a current design as shown, for example, in U.S. Patent No. 6,398,126. More of the front hinge moves at the junction of the member and the optic. The typical hinge width 丨丨 is 〇 5.0 mm, and preferably has a hinge base width as indicated by the arrow η in the longitudinal direction, such as 0.06-0.4 mm, and preferably 〇12 as seen in Figure 3. The wider hinge base 12 will stretch like a rubber band to promote greater forward movement of the optic 2. The hinge 10 is located on the front side and the rounded end 8 of the right loop 6 as seen in Figure 1 indicates that the hinge is at the highest point. The end 8 is circular. Preferably, the optical portion and the plate-like adhesive member are an anthracene resin and the ring 6 is a polyimide. There may be a central edge around the surface of Optics #2 to reduce the migration of cells across the lens after surgery, and thereby reduce the incidence of posterior capsule opacification and the need for YAG posterior capsule resection. As is well known in the art, after removal of the natural crystal, a small circular opening in the artificial hydrocele sclera, such as the one shown in the figure, is inserted into the capsular bag of the eye. Insert into the capsular bag through the corneal anterior capsular bag opening through the cornea or artificial crystal system. Adhesive 4 or ring cul-de-sac). The outer end of the adhesive ring 6 is positioned in the blister pocket of the capsular bag 10 200843706 or the outer end of the loop is closely adjacent to the pocket blister, and the loop is centered to deflect to conform to the inner surface of the capsular bag. The end or bulge of the loop is provided on the outer end portion of the loop 6 for fixation to secure the crystallite in a capsular bag or blind tube with fibrosis, and the fibrosis is used to surgically remove the central crystal The cortex and nucleus are gradually formed in the capsular bag. The inner end of the loop 6 may be integrally formed from the same material as the cleat* or the loop may be a separate material such as polyimine. If the loop is made by
