I consider myself EXTREMELY fortunate with the results that I have had. I was approx. -8.5 right eye and -4.75 left eye with high astigmatism in my right eye. After 7 months my left eye is now perfect, better than 20/20 and my right eye is marginally worse as I still have slight astigmatism. Considering some of the side effects I could have had (I did experience halo effect around headlights and street lights) I have had NO PROBLEMS WHATSOEVER. I do have some reservations about my vision in poor light...but doesn't everyone?!?!? I was particularly fastidious when it came to the aftercare treatment e.g. patches and glasses for two weeks afterwards.
