An example of removing a buried fixing thread...? Please recommend a hospital

It's been 10 years since I had surgery for burial, and the thread is exposed inside my eyelid, so I'm looking to remove it... I
 went to the doctor who did the surgery to ask about the surgical method, but he said it's a transparent thread, so he said he couldn't find it and told me not to touch it unless I'm going to have another surgery. For the second time, they said it wasn't their responsibility and told me to go to an ophthalmologist if I didn't see the eyes properly and had to have surgery again... Anyway,
 the doctor who did the surgery said he couldn't remove the threads
 
, so I searched online for ㄸㅋ, ㄱㄴㅅㅇ, ㅇㅇㅅ and got online consultation,
 but ㄱㄴㅅㅇ is a transparent thread. It seems that the ㄸㅋ can also be removed
 , but I was told to come to the hospital and
 the ㅇㅇㅅ cannot be removed because it is a transparent thread.. They said that it can be removed through an incision during reoperation...
 
If you have had the thread removed or are looking into it, please share some information.
