Kate's eye surgery is being postponed to some future date. It's not cancelled, since she'll have to have it eventually, but it might not happen for years. As long as her vision isn't being compromised, we can wait. The doctor decided that it wasn't as severe as it first appeared, so we'll go back in three months for another assessment.
Thanks for all the good thoughts. I feel much more relaxed knowing that although she'll have surgery for it at some point, she'll be older when it happens.
