I very nearly went for LASIK surgery. I decided against as my pupils were slightly too large for the machine they had (my pupil surface area was slightly larger than the area that particular machine could operate over). If there was dim lighting this would have been a problem with halo's at night etc. The surgeon was very good and advised that if I really wanted to still get it done I could but halo's may be a problem. Or he advised that I go elsewhere where there was a machine that could laser a larger area. From what I have read though some surgeons would not have been this honest with people and carried on regardless. So beware. I am still contemplating going to Manchester where they have a machine that can operate on a larger pupil area.
