The pad is encased in a titanium sheet and has holes for blood vessels to pass through. The posterior scleral reinforcement component is used to treat high myopia and the posterior scleral staphyloma, retinoschisis, holes, or detachment that accompany high myopia. It is used to shorten the axial length of the macula and reduce refractive power, thereby adjusting the eye's axial length. The posterior scleral reinforcement component for high myopia is implanted in the eye, using the support pad and support bars to provide long-term fixation of the posterior sclera, improving retinoschisis and vision.

[0047] In some embodiments, the high myopia posterior sclera reinforcement component further includes a reinforcement member 500. The reinforcement member 500 is connected to the support cushion 100 to enhance the strength of the support cushion 100.
[0048] In some embodiments, the reinforcement member 500 is a titanium sheet.
[0049] In some embodiments, a plurality of positioning holes 101 are provided on the third support bar 400 , and the reinforcement member 500 passes through the positioning holes 101 and the support pad 100 .
[0050] In some embodiments, the edge of the support pad 100 has a chamfered design, so that after the scleral reinforcement component for high myopia is implanted in the human eye, even if the reinforcement member 500 such as a titanium sheet moves, it will not damage the optic nerve.
[0051] The position of the reinforcement 500 in the support pad 100 has been improved. The edge of the reinforcement 500 is completely retracted in the support pad 100. In other words, the edge of the reinforcement 500 does not protrude from the edge of the support pad 100. This can prevent the reinforcement 500 from protruding like a titanium sheet and cutting the optic nerve. In addition, the reinforcement 500 can increase the pressure of the product, effectively improving or restoring the cracked part.
[0052] In some embodiments, the surface of the support pad 100 is an inwardly concave structure, and the surface of the inwardly concave structure of the support pad 100 is smooth. The inwardly concave structure of the support pad 100 can be designed by computer-aided precise simulation of the eye axis and eyeball.
[0053] In some embodiments, the thickness of the support pad 100 is 1.0-4.0 mm. This design makes the posterior scleral reinforcement component for high myopia thinner and lighter overall, reducing the foreign body sensation felt by the patient and increasing comfort. For example, in one specific example, the thickness of the support pad 100 is 1.0 mm, and in another specific example, the thickness of the support pad 100 is 4.0 mm. It is understood that in other examples, the thickness of the support pad 100 may also be 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, or other parameters.
[0054] In some embodiments, the surface of the first support bar 200 has multiple first grooves 201 that contact the eyeball to prevent the posterior scleral reinforcement component for high myopia from sliding within the eye. Preferably, the edges of the first grooves 201 are chamfered. The first grooves 201 facilitate ligation and fixation of the posterior scleral reinforcement component for high myopia, reducing the risk of the posterior scleral reinforcement component falling off. Furthermore, the chamfered first grooves 201 minimize the foreign body sensation when in contact with the eye, providing greater safety.
[0055] In some embodiments, the surface of the second support bar 300 has multiple second grooves 301 that contact the eyeball to prevent the posterior scleral reinforcement component for high myopia from sliding within the eye. Preferably, the edges of the second grooves 301 are chamfered. The second grooves 301 facilitate ligation and fixation of the posterior scleral reinforcement component for high myopia, reducing the risk of the posterior scleral reinforcement component falling off. Furthermore, the chamfered second grooves 301 minimize the foreign body sensation when in contact with the eye, providing greater safety.
[0056] In some embodiments, the surface of the third support bar 400 has multiple third grooves 401 that contact the eyeball to prevent the posterior scleral reinforcement component for high myopia from sliding within the eye. Preferably, the edges of the third grooves 401 are chamfered. The third grooves 401 facilitate ligation and fixation of the posterior scleral reinforcement component for high myopia, reducing the risk of the posterior scleral reinforcement component falling off. Furthermore, the chamfered third grooves 401 minimize the foreign body sensation when in contact with the eye, providing greater safety.
[0057] In some embodiments, the angle between the first support bar 200 and the second support bar 300 is 120°-185°. For example, in one embodiment, the angle between adjacent first support bars 200 and second support bars 300 is 120°. In another embodiment, the angle between adjacent first support bars 200 and second support bars 300 is 185°. Preferably, in one embodiment, the angle between adjacent first support bars 200 and second support bars 300 is 170°.
[0058] In some embodiments, a clearance portion 105 is provided at the edge of the support pad 100 to prevent damage to the optic nerve. The clearance portion 105 can be located between the first support bar 200 and the second support bar 300 and opposite to the third support bar 400.
[0059] In some embodiments, two elliptical through holes 102 are provided on the support pad 100 adjacent to the clearance portion 105. The long axes of the elliptical through holes 102 are arranged along the edge of the clearance portion 105. The two elliptical through holes 102 are arranged along the edge of the clearance portion 105. The elliptical through holes 102 allow blood vessels to grow through these holes.
[0060] In some embodiments, the support pad 100 is provided with a central hole 103. The central hole 103 allows blood vessels to grow through the hole.
[0061] In some embodiments, the support pad 100 is provided with a plurality of surrounding holes 104 surrounding the central hole 103. The surrounding holes 104 allow blood vessels to grow through these holes.
[0062] When the above-mentioned posterior sclera reinforcement component for high myopia is used, the support pad 100 is implanted into the sclera corresponding to the macula of the eyeball, and the curvature of the third support bar 400 can be adjusted according to the condition of the eyeball. The smooth structure at the end of the first support bar 200 and the second support bar 300 can facilitate the doctor to quickly pass the first support bar 200 and the second support bar 300 through the lateral rectus muscle, inferior rectus muscle and inferior oblique muscle.
[0063] Compared with conventional posterior sclera reinforcement devices, the above-mentioned posterior sclera reinforcement component for high myopia has the following beneficial effects:
[0064] (1) The first support bar 200, the second support bar 300 and the end of the second support bar 300 of the posterior scleral reinforcement component of high myopia are rounded, which avoids the risk of damaging the eyeball and reduces the patient's foreign body sensation.
[0065] (2) The support pad 100 of the posterior scleral reinforcement component for high myopia is designed into a sunken structure that can wrap around the eye axis and eyeball through precise computer simulation of the eye axis and eyeball, which can better fit the eye axis and eyeball and achieve a better pressing effect.
[0066] (3) The first support bar 200, the second support bar 300 and the second support bar 300 of the above-mentioned scleral reinforcement component for high myopia are all designed with clear scales, which allow medical staff to better judge the implantation position during surgery.
[0067] (4) The first support bar 200, the second support bar 300 and the third support bar 300 of the above-mentioned sclera reinforcement component for high myopia are all provided with corresponding chamfered grooves, such as the first groove 201, the second groove 301 and the third groove 401, which can prevent the sclera reinforcement component for high myopia from sliding in the eye, making it safer.
[0068] (5) The elliptical through holes 102 on the support pad 100 of the scleral reinforcement component for severe myopia can allow blood vessels to grow better.
[0069] The above is only an embodiment of the present invention and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the present invention and still fall within the scope of patent protection.
