It's possible that 22 years of strabismus be corrected with surgery?

Define correction: If you are refering to lining the eyes up so they point in the same direction, that might be possible with a skilled eye muscle surgery. The other issue is will it work. If the brain decided to shut off the input from that eye(ambliopia), the ability to regain that lost input deminishes with time. A discussion with your eye dr can give you guidance.
