Should I fly to Seoul for eyelid surgery? Has anyone experienced this?

I'm considering flying to Seoul for double eyelid surgery. While there are places that offer this in Vietnam, I've heard that Seoul has many experts and advanced technology. However, after calculating the total cost of flights, accommodation, recovery, etc., I'm not sure if it's worth it, especially since I'll have to take a few extra days off work.

On a related note, I'd also like to ask: if I were to fly abroad for a procedure, what should I consider? Should I research hospitals or clinics beforehand, or go through recommendations from friends? I'm also concerned about post-surgery follow-up and care after returning home – is it difficult?

Has anyone here flown to Seoul for cosmetic procedures? Could you share your experiences? I'm particularly interested in understanding the early healing process, as I'll need to take a flight a few days after surgery.
