Can I have eyelid surgery, but keep my monolid? (Photo)

I love my monolid, it's unique and makes me, me! The only problem I have is that one eye is a bit smaller than the other, which seems to be the case for many Asians, the only problem is, that I see people getting eyelid surgery for a double eyelid, something I do not want! I want to keep my monolid, but make sure both my eyes are the same size.
