[0025] Example 1:

[0026] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The top view cross-section of the guide groove B303 is annular, the top view cross-section of the opening 301 is trapezoidal, the side view cross-section of the guide groove A302 is arc-shaped, and the guide groove 304 runs through the interior of the base pad 1; the opening 301, the guide groove A302 and the guide groove 304 are each provided in four groups, with each group of guide grooves 304 being provided with four, and the openings 301 and the guide grooves A302 are arranged at equal intervals inside the extension plate 2; the extension plate 2 is fixed to the outside of the base pad 1, and the extension plate 2 is provided with suture holes 6 inside;

[0027] In this embodiment, the support frame 7 is fixed as a whole around the eyeball through the suture hole 6, so as to improve the overall stability of the support frame 7 and avoid slipping. The opening 301 is connected with the opening of the iris flap around the eye. When the intraocular pressure is too high and the aqueous humor is large, the aqueous humor enters the interior of the opening 301 through the opening, enters the interior of the guide groove B303 along the guide groove A302, and finally diffuses through the outlet groove 304, thereby increasing the aqueous humor outflow channel to evenly release the aqueous humor and avoid blockage due to the single outflow path of the support frame 7. The aqueous humor is evenly distributed on the outside of the base pad 1 under the action of the pressure difference, so that it is convenient to be absorbed by the surrounding connective tissue.

[0028] Example 2:

[0029] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The extension plate 2 and the suture holes 6 are arranged in a cross shape on the outside of the base pad 1. The base pad 1, the extension plate 2 and the bracket frame 7 are made of a soft electrospun membrane. A filling groove 4 is provided inside the bracket frame 7, and the inside of the filling groove 4 is filled with a cooling material 5. The cooling material 5 is made of polycaprolactone, and the filling groove 4 and the cooling material 5 are evenly spaced inside the bracket frame 7.

[0030] In this embodiment, the base pad 1, the extension plate 2 and the bracket frame 7 are made of a soft electrospun membrane, and its nanoscale structure can provide a very large surface contact area, which is beneficial to the attachment and growth of cells. At the same time, the high porosity helps the transmission of nutrients and oxygen, and is also beneficial to the discharge of waste, so as to protect the periorbital area and reduce side effects. The cooling material 5 is made of polycaprolactone, which releases cold energy during its degradation process, thereby reducing the temperature of the surrounding tissues, helping to reduce eye inflammation, and thus having a certain therapeutic effect on eye diseases such as glaucoma.
