My daughter required surgery, actually 2 (the 2nd was emergency). This was only because her hem was growing very rapidly, and into her eye, and affecting her vision. This was mandatory.
I do not think we would have agreed to surgery had it not been an emergency. There is so much they can do with laser, and if it is truly only cosmetic, I would also want to see if it goes away on its own. We had no choice, but given one we would have waited. My babe is left with a very bad scar.
just my opinion.
