I have just had a lens replacement procedure. I would recommend using Optical Express. If results are your main concern then I can tell you after 24hrs my eye site is much much better. I had my post op test this morning and went for lunch. I did not need glasses to read menu!! Of course there are always things which could have been done better. The practice in Southampton is a bit dated. A lot of the lights looked like they were installed twenty years ago. But its results that matter. I paid £6700.00 for my procedure. Personally I think its money well spent. My eye site is as it was twenty years ago. If that is what is important to you the go see Optical express.
