You have ptosis of your left upper eyelid. This is corrected by a ptosis repair, not a blepharoplasty, though the surgical approach (scar) can be the same. However, what is more important is why you have developed this in the last year and why the entire left side of your face has now also dropped. This needs to be investigated as soon as possible. There are a number of medical conditions that can give rise to your problem and if identified, appropriate treatment is necessary. Correcting your eyelid ptosis and facial drooping may only be treating the symptom, not the root cause.
Yes, surgery is the only option to remedy the drooping of your left eyelid. It is very important that you find a surgeon that recognizes that you have ptosis and require a ptosis repair. A blepharoplasty alone will not fix the drooping of your eyelid and can actually worsen the appearance of asymmetry. I hope this information is helpful.
