Hi. I'm online and happy to answer your question today.
Let's answer the second part first. Yes. That may have contributed to your poor hitting ability as you do not have normal depth perception because of your strabismus.
Surgery can be done to attempt to straighten your eyes but it will not improve your depth perception or vision at this point. It would be a cosmetic effect only. And, depending on how good your vision in your weak eye is along with other factors, you eyes may tend to drift back apart even if the surgery was successful initially.
I am sure that this type of surgery is available in Queensland. The doctor who does this type of surgery is a pediatric ophthalmologist. I know, at 50 you are no longer a kid :) but in addition to being experts on children's eye diseases, pediatric ophthalmologists are experts on strabismus, even in adults.
Does this make sense to you?
And, now, the obligatory word from our sponsors: :o)
