I had RK done on both eyes in 1990/91. Prior to that I was extremely short sighted(about 6/60 in both eyes) and had worn glasses and contacts permanantly for years.I did alot of physical sports (and still do)including surfing,swimming and martial arts, and was in HM Forces where wearing contacts can be a problem. I had one operation on my left eye, two on my right. The left eye is still perfect to this day, some 15 years later. My right eye has got weaker/developed an astigmatism in the last year or two, which seems to be worsened due to using computers alot.The astigmatism was present before the operation, and my eyesight is still nowhere near the levels I had before the Op.As well as the problems I had with sports, I had the op in order to meet eyesight standards for the police force, and have been in now for 14 years. If other people are considering surgery for the same reason, please be aware that some forces are now very 'funny' about people with any type of eye surgery and may not accept it.I dont know why as since the Op i have had no problems swimming,surfing,scuba diving,doing Judo or kickboxing!I do experience some 'Haloing' of lights when driving at night, although it is not alot different from glare I experienced when wearing contacts.I did find that you can buy glassses with asimple yellow tint lens for night driving,(bearing in mind I work night duties) which make a big difference.
