Could lasik fix accommodative esotropia? since esotropia is due to hyperopia, would lasik fix hyperopia and therefore eliminate esotropia?

Maybe: Lasik can correct hyperopia, to some degree, though does better on myopia and astigmatism. In accommodative esotropia there is an increased ratio of nerve signals to make the eyes turn in, as the person focuses more (to see things more closely). If the hypertopia is reduced, then the person does not need to focus as much, with a possible result that the accommodative esotropia may be lessened.

Maybe: Many patient with accommodative esotropia wear contact lenses successfully. If you are able to wear contact, lasik will also be successful. A minority of accommodative esotropia patient need bifocal to keep the eyes aligned at near. They may have a harder time with the lasik results. In general, lasik results for myopia and astigmatism are outstanding. The results for hyperopia are ok!

For an adult, maybe: Theoretically, in accommodative esotropia, the hyperopia just needs to be corrected in order to prevent the eyes from focusing too much and crossing. That can be from glasses, contact lenses, or refractive surgery. Since children are usually affected, refractive surgery is not an option. Their prescription is not stable and likely will improve over time. For an adult, this might be an option.

Maybe: If the esotropia is purely accommodative, correction of the hyperopia should improve the control of your eye alignment. If the esotropia is gone with glasses and/or contact lenses, then lasik will likely eliminate it as well.
