Thanks a lot for the answer
Amblyopia is very difficult and often impossible to improve after age 5-6. With the cataract off its no likely that his vision will recover to 20/20
It will take several months to know how much comes back.
Also realize that the incidence of amblyopia is about 2% EXCEPT in families where someone has amblyopia then it jumps to 20%. Everyone in your family with small children should have them examined by an Eye MD by age 3 at the latest.
