I'd be a bit mad myself in that case, any board certified ophthalmologist should be well aware of the use of surgery as a treatment for strabismus; especially ones specialized in pediatric ophthalmology since it's better to take care of it at a young age while there's higher neuroplasticity (so a higher chance of the brain properly adapting to the corrected vision).

Maybe it's less of a thing in France, or it was at the time (early 2000)? You're right about neuroplasticity, even if I get it fixed now I don't know if my brain would adapt to it.

  I had my first strabismus surgery in the early 80s in the UK. It was not considered unusual and was handled in the local hospital. The technique has barely changed since 1839, apparently. [1] After surgery, there are some simple interventions, like wearing a patch covering your 'good' eye the majority of the time, so that your other eye gets wired in more. However, they recommend against this if the eye is unlikely to gain much function. Also, do note that, unless you had stereoscopic vision before age 3, almost all specialists believe you can never gain stereoscopy, but you can probably regain some function. (There are signs that VR headsets can help people or regain stereoscopy, in some cases.

    > here are signs that VR headsets can help people or regain stereoscopy, in some cases. Personal anecdote: I purchased myself a Valve Index ~2 months ago, and have noticed changes in my visual perception after use including limited stereoscopy and general improvements in my binocular fusion (as I said above, my left eye mostly provides limited peripheral vision - but following a VR session I will see my field of view expand on the left side and more of that eye is now being used). At 30 years old this is something I never would have believed possible, especially given it never happened following my two surgeries when I was younger. Do I think VR is going to restore my limited binocular function to what it would otherwise be at my age? Not with my corrected vision in my left eye being so much worse than my right, full binocular fusion just isn't going to happen (I can force it and it gives me a migraine within minutes). Do I think there's more than "signs" that it can help people with less severe gaps between their corrected vision (re)gain full binocular fusion and stereoscopy though? If I can see improvements I have no doubt that somebody with a less severe case can get back what they should have had in the first place.
