[0002] Posterior scleral reinforcement surgery, also known as posterior scleral strap surgery, posterior scleral support surgery or posterior scleral strengthening surgery, is the use of allogeneic or autologous biological materials or artificial synthetic materials to reinforce the posterior sclera of the eyeball. The operation is performed on the posterior sclera, usually the back of the macula, by using biological or non-biological materials to reinforce the weak area of ​​the posterior sclera. The reinforcement material is fixed to the surface of the posterior sclera to play a mechanical reinforcement role.

[0003] After searching, it is found that the announcement number is CN117838379A, which is an elastic bracket for the posterior sclera, including a base frame, an oblique beam, a bracket, a concave mold, a biological patch and a support rod; the characteristics are: a semi-annular oblique beam extends downward from the middle of the semi-annular base frame, and the open ends of the oblique beam are connected to the open ends of the semi-annular bracket; there is a crescent-shaped concave mold on the semi-annular bracket; and a crescent-shaped biological patch is covered on the semi-annular bracket.

[0004] However, a posterior scleral elastic bracket similar to the above-mentioned one has a larger arc surface on the upper end of the base, which increases the size of the surgical opening, increases the steps and time for suturing, and when it is delivered to the posterior sclera, the increased volume makes it difficult for the staff to adjust its position through the clamp.
