Blepharoplasty waiting times?

[drspouse]

I've been referred by the optician to the NHS hospital for a blepharoplasty due to one eyelid impinging on my vision, I think the original referral was a couple of months ago. It has been a long standing problem but has got worse - age, apparently the fact I wear contact lenses so move my eyelids manually every day makes it get worse faster, the natural arrangement of my eyes, and I've noticed it more with more computer/close work over lockdown.
Does anyone have an idea of the waiting list time for this?
