It's a common operation in Western countries, too, I actually know people (in Asia as well as Europe) who have had this operation. The good news are that scarring, pain, risks, recovery time and cost should be quite minimal on your typical cosmetic surgery scale. It IS a surgery, though, so one shouldn't go for one too lightly however.
If you really feel it's the right choice for you, I don't want to discourage you, but I hope improving your chances in dating isn't your main reasoning for it. You look fine to me in your pictures, but that's just me. Try to think it through, you know what's the best for you.
