My son had this surgery, so I know how your feel about wanting to see the results. I don't think 2 weeks without glasses hurt, so just keep her glasses on as much as possible and the resting eyes should get more centered. Your surgeon would know best if the missing glasses caused problems. Each cas is individual.
After my son's surgery, we had a 6 month check-up and were told that they would wait until the 1 year check-up to decide whether to remove the prisms completely. Each case is individual. Although a slight prism has been required, he can look me squarely in the eyes when he takes off his glasses. I am thrilled that he isn't bruised from falling hourly. He is in fifth grade and can ride his bike for hours without accidents. I am so greatful for the changes.
He does choose to put his glasses on when his eye gets tired -- he reads a lot and is taking music lessons. His 2nd year checkup is this month, so maybe the slight prism can be removed.
You should have been told that the results may not be permanent since "repaired" muscles are never as perfect as "birth perfect". Medical technology has reduced the scarring from repairs to the muscles, but you don't want that done too often. From what I'm told, each case is individual.
The surgeon said they might need an aditional surgical adjustment in his twenties, but metabolism and individual preferences will be taken into account.
