I have just had my eyes checked again at Accuvision,13 months after I had my eyes done, purely to make sure that all is on track, as I have not had any problems however did so just to be on the safe side - they are in execellent condition and have better than 20/20 vision. I am still thrilled with the results and the professional care I received from Accuvison - would strongly recommend as my experince has been 100% positive.
