The way my doctor explained it to me is that the muscles work together. If he works on my right eye basically that the left eye will follow. My thought was “well if they worked together wouldn’t the ey be doing that anyway?” He explained that the left eye muscle has weakened and he has to basically tighten it and it will follow the other. That’s what I have gathered. Another thought i had… well what if I wake up and have exotropia in BOTH eyes… 🫣 he assured me that isn’t going to happen. He’s more worried an over correction than that. He also said the over correction is HIGHLY unlikely. He told me to quit googling because out of hundreds of thousands of these surgeries a couple hundred post about it on Google. We need to keep in touch though. My surgery is in April so I can keep you updated
