Is there a high chance of epicanthoplasty failure?

I'm so timid that I think this question is a bit meaningless, but there are many people who look crowded with epicanthoplasty and their front looks strange and fierce... I see some people regretting it, and around epicanthoplasty, most people who have epicanthoplasty are successful with a slight opening, but if you even do epicanthoplasty, it's too much work. I'm thinking of only having a double cup because I'm afraid it might burn me, but looking at the current trend, it seems like the front gap is almost standard... The doctor also says to do it, but is it a good idea to do it?
