Is there any way you can get her operation done any sooner? Can you possibly afford the surgery privately? I say this because she will be five by the time she has it done - is that correct? And, speaking from experience, if the turn has been very bad, I don't mean to alarm you, but she may not recover accurate vision in that eye and the surgery may well be purely cosmetic. I had the same thing happen to me when I was little, because my mother never picked up on the turn, and while my eyes are perfectly straight, I am legally blind in the eye that was turned. The brain turns off the messages from that optic nerve because it is just too confused to get the garbled message from two out-of-alignment eyes, and the longer that happens for, the harder it is to "switch it on" again, so to speak.

Good luck.
