Had lasek surgery on both eyes at Finchley Rd Optimax some 3-4 years ago, can't remember exactly when. Going in I was minus 11, with astigmatism, so pretty bad. Op took less than ten minutes, no pain, just a vague stinging like you get when there's a bit of soap in your eye. Didn't bother using the paracetamol tabs they gave me. Have needed nothing since, eyesight is fab, some light scatter from headlamps but nothing intolerable, low light vision is not super but it wasn't before. The pros outweigh the cons by about 9999 to 1. Lasek is without question the most worthwhile thing I have ever done for myself.
