I have a scar tissue on my right eye back in 2003 they were unable to do surgery. Now in 2008 with advanced technology they were able to do Lasek wave front with out interfering with the scar tissue. Consultant Trevor Pilley was excellent and gave me the good news surgery was very much possible, i saw the surgeon Stefan Klopper and he confirmed 100% they could now do surgery with the latest technology with out causing any problems with the scar tissue. The procedure was pain free and i am over the moon with the results, words cannot express.......i would recommend Optical express (Milton Keynes) to anyone. i have gone from -7.00 to 20/20!!!!!!!!!
