I am a community leader here, not a doctor. I am also an experienced eye patient. Welcome to our community
I am so sorry that your son had an accident, and that now he has vision problems.
The doctor will advise you.
I encourage you to follow up with us, and to respond to other community members, so that all of us can help each other learn about our eye care.

You will need to allow everal months to go by for him to recover from this surgery and let the swelling go down (perhaps 3-6 months). They he needs to see a strabismus (eye muscle) specialists ophthalmologist. They are often called "pediatric ophthalmologists". Your present surgeons can make the referral.
No need to leave home. India has many find strabismus specialists but I cannot give you a name or institution that is best.
