Is it possible to have permanent blurry vision after a mullerectomy?

I am 12 days out from my surgery for a slight drooping of the right eyelid caused by a 2nd strabismus surgery 4 yrs ago. So far, it looks like a decent height, even though later the Dr admitted he didn't think he corrected it enough. But ever since the surgery, I have a slight blur to my vision in the eye, and I'm worried there is some kind of permanent "warping" of the cornea. I have been fighting blurred vision in my left eye due to multiple chalazion cysts, but those are at least removable!
