Will squint surgery improve vision?

Hi doctor,

I am a 29 year old male. My left eye is not entirely blind, but if I watch a powerful light, I just see a low white light. This problem is about 23 years. Is it due to retinal detachment and it has become squint heavily. I repaired my detachment with scleral buckle nine months ago, and it is the same likely previous time. If I want a strabismus surgery now, is it possible? What should be the minimum gap between these two surgeries? Are there any risks of my squint surgery? I have got surgery in my eyes thrice previously. First time for cataract, second time retinal detachment repair with silicon oil and the third time for silicon oil removal. I also have rubber or scleral buckle inside of my eye. Will they get removed during the strabismus surgery? Will strabismus surgery affect my good vision that is, my right eye? If yes, then how long will it take to recover? If the answer no, then please explain me the real reason. I am asking all the above as a second opinion from you before heading to the operation. Thank you.
