My vision has been excellent after the treatment but I have to say that whether its because I am getting use to it or my vision is starting to deteriorate again I am not sure. The worst problem was always driving at night but this is still very good its mostly of a morning I find that my eyes are caked with 'sleep' for want of a better word. When I have been up for a while there are no problems and want to thank ultralase for starting my life again for me.
