It's been 2 years since I had my eyelid
 surgery done. It wasn't as simple a surgery as I thought 
 (I had a meltdown when I cried blood),
 but I'm generally satisfied. I don't ask myself if I'm tired anymore. However,
 
the undereye eyelid area was awkward for a year
 (I felt like an avatar...),
 but the under eyelid area has recovered a lot, but
 the undereye area has improved a lot. I thought it was just aging
 because the wrinkles were diagonal, 
 but when I saw celebrities like Sung Dong-il and Jeon Hyun-moo with under-eye areas, they looked similar, so I guess it was just my mood... 
 
Anyway, instead of getting brightness under the eyes,
 I got wrinkles, but it's not necessarily because of the surgery. I'm experiencing accelerated aging after I'm in my 40s.
 I don't want to have to undergo this surgery again, so I hope it doesn't recur, but
 I'm worried because I've seen reports
 of people having relapses. How many years did it take for those who relapsed to relapse?
