Eye Turn Surgery is it safe?

My boy of 2 has severe eye turn in right eye have been told that only surgery will correct the turn its at a scale of 50 he will live with this until he is at least 40 ish unless we have surgery which will hopefully straighten he is slightly long sighted with prescription of +1.25 which orthoptic clinic say its not enough to warrant a 2 year old wearing glasses his right eye when tested is not as sharp as left eye as the pictures they showed him far away that were tiny he only got correct on second time of asking but she is not concerned his sight is suffering too much she also says the eye turn surgery is purely cosmetic and he still may need patching to help that right eye get stronger in near future but for now they keeping close eye and seeing regularly i dont want my boy getting picked on throughout his school years like my best friend did but how succesful are these ops has anyone had to go back have it done more times obviously is a slight chance it will go back but can have op done again i am just so scared and confused by it all she said no amount of glasses or patching will make that turn go it may make it less noticeable but not gone like surgery would is this scale of 50 the worst case then? any professional opticians out there or surgeons ???
