A friend of mine made it at Tianyou Hospital. It was very good, so I went. Because I just did it, and I'm still recovering. My eyes are still swollen, so I can't tell you the effect. Now that the line has been buried, don't entangle it any more. You can bury the thread for a few years, and then you can open your eyes in a few years. And the time to bury the thread and return to nature is shorter! When I went, she didn't say anything about the difference between imported thread and ordinary thread, and gave me a box of thread directly! Don't worry, after all, burying thread is less risky than cutting in all aspects!
