Description

Technical Field

[0001] The invention relates to the field of medical equipment, in particular to an intraocular implant which can form an artificial pupil with a rearward position and a capsule space for accommodating and fixing an artificial lens after implantation. Background Art

[0002] The iris belongs to the middle layer of the eyeball, in front of the ciliary body, and has the function of automatically adjusting the size of the pupil and the amount of light entering the eye. The pupil of a normal human eye is 3.5-4.5mm. When the light is strong during the day, the pupil shrinks, and when the light is weak at night, the pupil expands. By automatically adjusting the size of the pupil, the amount of light entering the human eye can be controlled, and the human eye can quickly adapt to different lighting environments. If the human eye is without iris or has iris defects due to trauma or congenital eye abnormalities, the light entering the human eye is no longer regulated and controlled, and the eyes cannot be opened in a strong light environment, causing glare, photophobia and other phenomena.

[0003] As a biological soft tissue material, the iris has viscoelastic properties such as hysteresis, relaxation, creep, and strain rate correlation. The important mechanical properties of the iris make it difficult to repair when aniridia or iris coloboma is caused by eye trauma or congenital eye abnormalities, resulting in functional abnormalities of the eyeball, such as spherical aberration, increased aberrations, diplopia, glare, photophobia, amblyopia, post-traumatic low vision, and reduced visual acuity.

[0004] Since the atrophied iris cannot be regenerated by drugs or other means, it can only be repaired by surgery. Common surgical methods include iris suturing and artificial iris implantation. Iris suturing uses the elasticity of the patient's remaining normal iris tissue to stretch and sew the iris tissue together, which plays a certain role in controlling light and limiting aberrations.

[0005] The best way to treat iris defect or loss is to implant an intraocular implant artificial iris to replace the damaged natural iris. Intraocular implant artificial iris implantation is to use artificial synthetic materials to partially or completely replace the natural iris. However, there is no synthetic material that can completely replace the natural iris. The current products are all equipped with an iris diaphragm on the hard artificial lens. The material is polymethyl methacrylate, which requires a larger surgical incision. The incision size is mostly more than 10mm. The implantation process is relatively complicated, and the surgical effect and promotion are limited. The ideal intraocular implant artificial iris material should have similar properties to the natural iris, with viscoelastic properties such as hysteresis, relaxation, creep, and strain rate correlation.

[0006] Traumatic iris injury is often accompanied by lens damage, capsular bag damage, etc., which makes it difficult to fix an artificial lens even if an artificial lens is implanted. Therefore, when an intraocular artificial iris is implanted to replace the damaged natural iris, an artificial lens also needs to be implanted. However, due to the capsular bag damage, the implantation position and fixation of the artificial lens is a big problem at this time.

[0007] Currently, the main methods for fixing intraocular implants are suture fixation and loop support.

[0008] The suture fixation method is to pass the suture through the tissue and then fix the implant with the thread, but the limitation of the above method is that the intraocular space is limited, the suture overlap in the eye is very difficult, the surgical operation is difficult, and the surgical effect is limited.

[0009] The loop support method is to use the loop to support the end of the closed space in a confined and closed space to play a supporting role. This surgical method is simple and easy to operate, such as the intra-capsular fixation of artificial lenses. However, the limitation of the above method is that the surgery can only be performed in a closed space, and it is not suitable for the fixation of artificial iris intraocular implants and artificial lenses in the anterior chamber angle or ciliary sulcus.

[0010] Existing intraocular implant artificial iris surgeries usually use sutures to fix the artificial iris on the remaining iris or at the root of the iris, or in the ciliary sulcus. This method requires complex suturing and knotting operations in the narrow, closed space inside the eye. The operation is difficult and limits the implementation of the operation, so many patients with iris defects cannot receive effective treatment.

[0011] In addition, patients whose irises are damaged due to lesions or trauma often have concomitant lens diseases or trauma, which may not only lead to cataracts, but also lesions or damage to the lens capsule, making it more difficult to fix the artificial lens.

[0012] Currently, artificial irises and artificial lenses are mostly processed by machining or molding. Due to the defects of traditional processing methods themselves, many artificial irises designed with complex structures cannot be realized.

[0013] In the published patent CN 102090942 A, it is mentioned that a capsular bag is formed by a transparent film at the back and an artificial iris at the front. The capsular bag is behind the artificial iris and pupil, and there is a protrusion inside the capsular bag to fix the artificial lens. This type of structure cannot be realized by traditional machining or molding processing methods.

[0014] In addition, in patent CN 102090942 A, the pupil of the artificial iris is designed on the front surface of the implant, and the artificial lens fixing structure is designed on the rear surface or behind the artificial iris and pupil. After the artificial iris is implanted, it becomes very difficult to implant the artificial lens, and it is difficult to operate and adjust the center of the artificial lens. Summary of the invention

[0015] In order to overcome the defects of the prior art, the present invention provides an intraocular implant, which comprises a first component, a second component and a capsular bag formed by the first component and the second component. The circumferential edge of the first component and the circumferential edge of the second component are connected to each other to form a capsular bag between the first component and the second component, and the capsular bag is used to accommodate an artificial lens.

[0016] Specifically, the present invention relates to the following contents.

[0017] According to the present invention, the first component of the intraocular implant includes a first disc, and the first disc has an elliptical hole located in the center. According to the present invention, the short axis of the elliptical hole is designed to be the same size as the optical zone of the artificial lens, which can prevent glare and prevent light from passing through the edge of the artificial lens and then passing through the pupil to cause glare. According to the present invention, the long axis and the short axis of the elliptical hole can gradually shrink from the front surface of the first component to the rear surface of the first component. The intraocular implant is fixed to the scleral wall by the loop on the first component, and is stably fixed to the scleral wall by loop fixation or suture fixation, which is stable, reliable and easy to operate.

[0018] According to the present invention, the second component includes a second disk having a circular hole located in the center, which forms an artificial pupil that is positioned backward. The artificial pupil that is positioned backward can provide higher imaging quality, and a smaller artificial pupil can achieve the function of a large pupil that is positioned forward, while reducing the size of the artificial lens.

[0019] According to the principle of light propagation, the closer the pupil is to the retina, the smaller the pupil size is required to pass the same light. Under normal circumstances, the pupil size of the human eye is about 3.5-4.5mm. The size of the pupil after the artificial pupil position is moved back is compared with the original normal position, and the calculation is as follows:

[0020] Original pupil size / mm Backward distance / mm Artificial pupil size after backward movement / mm 3.5 1.7 3.27 4.0 1.7 3.74 4.5 1.7 4.20 3.5 2.0 3.24 4.0 2.0 3.70 4.5 2.0 4.15 3.5 2.2 3.21 4.0 2.2 3.67 4.5 2.2 4.12

[0021] Note: 1) The original pupil was located in front of the lens. After the backward movement, the artificial pupil is located behind the lens and close to the lens.

[0022] 2) The size change after the posterior shift is related to the lens power. Here, the calculation is based on a 20D lens as a reference.

[0023] According to the present invention, the second component includes a curved surface at the circumferential edge and is connected to the first component via the curved surface, thereby forming a pocket, such as Figure 2 As shown. The capsule bag has two openings, the first opening of the capsule bag is the elliptical hole of the first component, and the second opening of the capsule bag is the circular hole of the second component. The capsule bag is used to accommodate and fix the artificial lens. The artificial lens can be stably fixed in the capsule bag formed by the first component and the second component by using the loop of the artificial lens. The artificial lens is located behind the elliptical hole of the first component and in front of the circular hole (i.e., the artificial pupil) of the second component. The elliptical hole of the first component facilitates the implantation and position adjustment of the artificial lens. The artificial lens is in front of the artificial pupil, which can improve the optical quality. The artificial lens is implanted through the elliptical hole of the first component, which is convenient to operate, safe and reliable.

[0024] According to the present invention, the diameter of the first component is 9.0-13.0 mm and the thickness is 0.2-0.5 mm. Preferably, the diameter of the first component is 10.0-12.0 mm and the thickness is 0.3-0.4 mm.

[0031] According to the present invention, when the intraocular implant is implanted in the eye, the front surface of the first component is 2.4-3.7 mm away from the cornea.

[0032] According to the present invention, the intraocular implant is manufactured by 3D printing, machining or mold casting.

[0033] According to the present invention, the intraocular implant is made of a flexible polymer material or a biological material that can be used for intraocular implantation.

[0039] According to the present invention, the intraocular implant can be processed by machining and mold casting. In addition, the intraocular implant can also be processed by 3D printing, so that it can be processed into a more complex structure, solving the problem of complex structures that cannot be processed by machining and mold casting.

[0057] Figure 1 shows a schematic structural diagram of an intraocular implant according to the present invention, and Figure 2 A schematic side view of an intraocular implant according to the present invention is shown. Figure 1 and Figure 2 As shown, the intraocular implant according to the present invention comprises a first component and a second component. The circumferential edge of the first component and the circumferential edge of the second component are connected to each other to form a capsular bag between the first component and the second component. The capsular bag is used to accommodate an intraocular lens. The first component comprises a first disc having an elliptical hole located in the center. The second component comprises a second disc having a circular hole located in the center.

[0058] The first component and / or the second component of the intraocular implant of the present invention can be a single-layer structure. The first component and / or the second component of the intraocular implant of the present invention can be a single color or can have multiple colors. For example, the first component and / or the second component of the intraocular implant of the present invention can have one or more of black, brown, blue, brown, green, and red.

[0059] The first component and / or the second component of the intraocular implant of the present invention can be a multi-layer composite structure. Each layer of the multi-layer composite structure can be a single color or can have multiple colors. For example, each layer of the multi-layer composite structure of the first component and / or the second component of the intraocular implant of the present invention can have one or more of black, brown, blue, brown, green, and red.

[0060] The first component and the second component of the intraocular implant of one embodiment of the present invention are both black single-layer structures, such as Figure 3 shown.

[0061] The first component of the intraocular implant according to one embodiment of the present invention is a single-layer structure having multiple colors (ie, multi-colored).

[0062] The first component of the intraocular implant of one embodiment of the present invention is a three-layer composite structure, which includes a first layer, a second layer and a third layer, wherein the first layer is white, the second layer (which is located between the first layer and the third layer, also referred to as the middle layer) can be a color structure of, for example, red, brown, and blue, and the third layer is white. In this embodiment, the white color of the first layer and the third layer of the first component is the color of the material itself, and the second layer (middle layer) is colored. This sandwich-like structure surrounds the color in the middle layer, which can prevent the color from leaching, thereby better simulating the color of the natural iris, such as Figure 4 shown.

[0063] The second component of the intraocular implant of one embodiment of the present invention is a three-layer composite structure, which includes a first layer, a second layer and a third layer, wherein, for example, the first layer is white, the second layer (which is located between the first layer and the third layer, also referred to as an intermediate layer) is a plurality of colors, the third layer is white, and the first component is a single-layer structure having a plurality of colors (i.e., multicolored), e.g. Figure 5 The intraocular implant of the present invention may also have a multi-layer composite structure with other colors and / or color combinations.

[0064] In some embodiments, the first component has a diameter of 9.0-13.0 mm and a thickness of 0.2-0.5 mm, preferably, the first component has a diameter of 10.0-12.0 mm and a thickness of 0.3-0.4 mm. In an intraocular implant of one embodiment of the present invention, the first component has a thickness of 0.3 mm and a diameter of 11 mm, such as Figure 6 shown.

[0065] In some embodiments, the length of the major axis of the elliptical hole of the first component is 7.0-9.0 mm, and the length of the minor axis of the elliptical hole of the first component is 4.5-6.5 mm. Preferably, the length of the major axis of the elliptical hole is 7.5-8.5 mm, and the length of the minor axis of the elliptical hole is 5.0-6.0 mm. In an intraocular implant of an embodiment of the present invention, the length of the major axis of the elliptical hole of the first component is 8 mm, and the length of the minor axis is 5.5 mm. Figure 7 shown.

[0066] In an intraocular implant of one embodiment of the present invention, the major axis and the minor axis of the elliptical hole of the first component gradually shrink from the front surface of the first component to the rear surface of the first component. Figure 8 For example, the length of the major axis of the elliptical hole in the front surface of the first component is 8.5 mm, the length of the minor axis is 6.0 mm, and the length of the major axis of the elliptical hole in the rear surface of the first component is 8 mm, the length of the minor axis is 5.5 mm.

[0067] In an intraocular implant of one embodiment of the present invention, the second component is black and opaque, which can prevent light from passing through the second component. Fig. 9 In some embodiments, the diameter of the second component is 9.0-13.0 mm and the thickness is 0.3-0.6 mm, preferably, the diameter of the second component is 10.0-12.0 mm and the thickness is 0.4-0.5 mm. In an intraocular implant of one embodiment of the present invention, the thickness of the second component is 0.5 mm and the diameter of the second component is 11 mm.

[0068] In some embodiments, the total thickness from the front surface of the first component to the rear surface of the second component is 0.8-2.0 mm, preferably 1.0-2.0 mm, more preferably 1.2-1.5 mm. In an intraocular implant of one embodiment of the present invention, the total thickness from the front surface of the first component to the rear surface of the second component is 1.2 mm.

[0069] In some embodiments, the diameter of the circular hole of the second component is 2.5-5.0 mm, preferably 3.2-4.2 mm. In an intraocular implant of one embodiment of the present invention, the diameter of the circular hole of the second component is 3.27 mm. In this case, according to the previous calculation, it is equivalent to the size of the artificial pupil obtained by shifting the original 3.5 mm natural pupil backward by 1.7 mm.

[0070] In an intraocular implant of one embodiment of the present invention, Fig.10 As shown, the one or more tapered holes in the second component gradually shrink from the rear surface of the second component to the front surface of the second component. The diameter of the tapered hole in the rear surface of the second component is 0.4 mm, and the diameter of the tapered hole in the front surface of the second component is 0.3 mm. In some embodiments, the angle formed by the one or more tapered holes and the second component is 30-60 degrees, preferably 31-45 degrees. In an intraocular implant of one embodiment of the present invention, the angle formed by the one or more tapered holes of the second component and the second component is 45 degrees. The tapered hole can be used as a channel for the circulation of aqueous humor, so that the aqueous humor can flow freely in the anterior chamber and the posterior chamber. The diameter of the tapered hole serving as the aqueous humor circulation channel is preferably between 0.3-0.4 mm, considering that the thickness of the second component is preferably 0.40-0.50 mm, as shown in FIG. Fig.11 Through simulation, the optimal value of the angle ∂ between the tapered hole and the second component can be obtained, as shown in the following table.

[0071] Conical hole diameter mm Second component thickness mm Angle ∂ (degrees) 0.30 0.40 36.1 0.30 0.50 31 0.40 0.40 45 0.40 0.50 38.6

[0072] In some embodiments, the inner diameter of the capsular bag is 8.4-12.4 mm, preferably 9.0-11.4 mm, and the height of the capsular bag is 0.3-0.7 mm, preferably 0.4-0.5 mm. In an intraocular implant of one embodiment of the present invention, the inner diameter of the capsular bag formed by the first component and the second component is 10.2 mm. After the haptics of the intraocular lens are unfolded, the intraocular lens is fixed in the capsular bag formed by the first component and the second component, such as Fig.12 shown.

[0073] In some embodiments, when the intraocular implant according to the present invention is implanted in the eye, the front surface of the first component is 2.4-3.7 mm from the cornea.

[0074] In some embodiments, the intraocular implant according to the present invention can be manufactured by 3D printing, machining or mold casting.

[0075] In some embodiments, the intraocular implant according to the present invention may be made of a flexible polymer material or a biological material that can be used for intraocular implantation.

[0076] In an intraocular implant of one embodiment of the present invention, the light transmittance of the opaque portion of the intraocular implant in the wavelength range of 300nm-1100nm is not greater than 0.54%. Fig.13 shown.

[0077] The average size of a human eyeball is about 11.0mm, with small ones being 9.0mm and large ones being up to 14.0mm. In order to meet the needs of more patients, the diameters of the first component and the second component can be preferably set in various specifications of 10.0-12.0mm. The anterior chamber depth of the human eye is about 2.8mm, mostly between 2.4mm and 3.7mm. The implantation position of this intraocular implant is affected by the intraocular space. After implantation, it cannot produce high intraocular pressure and cannot damage corneal endothelial cells. Therefore, the thickness of the entire intraocular implant (the distance from the front surface of the first component to the back surface of the second component) is preferably not more than 2.0mm. Of course, the smaller the better. However, an artificial lens must also be placed in the intraocular implant. Depending on the optical power of the artificial lens (from -10D to +36D), the central thickness is approximately 0.20mm~1.2mm (depending on the different refractive index of the material). The degree will be different), so after the optimized design, the front surface of the biconvex intraocular lens can be embedded in the elliptical hole of the first component, and the rear surface of the intraocular lens can be embedded in the artificial pupil of the second component, so as to reduce the height of the intermediate capsular bag formed by the first component and the second component. Using a +36D intraocular lens and an artificial pupil diameter of 3.5mm, it is calculated that the capsular bag height required for a +36D intraocular lens is not less than 0.415mm. The larger the pupil diameter, the smaller the required capsular bag height, the smaller the optical power of the intraocular lens, and the smaller the required capsular bag thickness. Therefore, the preferred capsular bag height of the present invention is 0.40~0.50mm. The second component needs to satisfy the requirement of the intraocular implant that the light transmittance is less than 1% within the wavelength range of 300nm-1100nm. The second component of the intraocular implant can be composed of three layers, including a transparent or opaque first layer and a third layer, and the middle second layer is an opaque part composed of multiple colors; of course, the second component can also directly satisfy the requirement of a one-layer structure that the light transmittance is less than 1% within the wavelength range of 300nm-1100nm. Considering the structure and performance of the second component, the thickness of the second component is preferably 0.40-0.50mm; as for the thickness of the first component, mainly considering the structure, strength and processing of the component, the thickness is preferably 0.30-0.40mm, so the thickness of the entire intraocular implant is preferably 1.2-1.5mm.
