Squint + ptosis + lazy eye correction.

Hello Doctor, I have a lazy eye in right eye which also slightly tilts cross right(upper) side. Along with this I have also been imbalanced eyelid. As I was asked to wear a lens during my childhood in the lazy eye n due to forceful trials on right side, i got droopy cheeks. I will be opting for facelift in future. I'm also looking forward for the correction of my imbalanced eyelids and squint. I would like to what can be done n where to get the correction. Will it be considered as cosmetic surgery?  If no, then what is the difference between cosmetic eye surgery and correction surgery? Will there be difference in results? Approx cost of the treatment. Please help and suggest the best. Thank you in advance.
