1. Eye surgery may uncross your eyes and make they anywhere from straighter to straight to overcorrected and they could turn out.
2. Even if the first surgery is successful there is more than even money that over the next 25 years they will drift back in. This is due to the face that crossed eyed people don't have good fusion and fusion is what locks them in. So your eyes are like boats withour a rudder.
3. Eye muscle surgery will NOT make you see better. If one eye does not see nearly as well as the other then its likely you have amblyopia. If your vision cannot be corrected with glasses or contacts surgery will not help the vision.
4. See an Eye MD ophthalmologist that specializes in strabismus surgery (pediatric ophthalmologist).
5. If you have children, grandchildren, nieces or nephews have them checked early like age two years old as there is a 20% chance they will have amblyopia or strabismus.
You need to consult an ophthalmologist who specializes in strabismus (sometimes called a pediatric ophthalmologist, although they also see adults). If you live in the USA, you can use the directory at www.aao.org to find a board-certified specialist. If money is a big concern, you might try contacting the ophthalmology department of a teaching hospital in your area. They may offer a sliding fee scale to see a resident or fellow.
