all I know is that my son (almost 4) was NOT happy WHATSOEVER when they put the drops in to dialate his eyes a few months ago. First drops were okay going in, but then you have to put in the second drops, then that burns for a little bit. I was getting my eyes examed at the same time, but my Mom says that she and the nurse had to hold his hands and feet down to get the drops in. I could hear him screaming from a few doors down. He was NOT a happy camper, but got over it. I think in one year when it's time to go back he will likely NOT want that. Be sure to have a very very very good reward for her for being such a trooper. Let her scream or cry, but if you get those drops in, let her have that reward. And perhaps have a little reward for everything she cooperates with, ie, when the doctor/nurse says "read this line" or "read these letters" or "hold this over your right eye and read these letters" etc. I gave my son a couple bites of popcorn, Nerds, anything small and quick.
