Both of mine were done on the NHS last year. They were effecting my vision. I found the actual procedure very painful, local anaesthetic was given by injection into each eyelid (this was the painful bit). I wanted to get off the operating table and run away, It actually made me feel very bad and shocked. Took me a good 24 hours to recover from that. Had I known I would probably have taken something beforehand to relax me
As Larhyrus says had to sleep more or less upright for a couple of nights, lots of facial bruising which was rather embarrassing, but that faded in about seven to ten days. Also took far longer for the eyelids actually to fully heal, One in particular was still quite painful if touched upto three months later.
I felt the whole thing was rather brutal, and would not have it done again. Okay, the final effect, now some eight months later is good and my peripheral eye tests are much improved.
