The actual process itself isnt too bad at all,just the sensation of pressure-its all over so quickly.It was very uncomfortable for the first hour on the journey from Bristol to Exeter, I was hypersensitive to light and could not open my eyes. It eased up considerably after the prescribed rest period.After my one week consultation I had the fantastic result of 20/20 vision in my weaker eye and better than 20/20 in my right. IT REALLY IS WORTH IT!. Dont feel that you automatically have to go for wavefront,being the latest method,(UNLESS SPECIFICALLY ADVISED TO) it is more expensive and I am proof of the equally great effect of this other technique. I recommend that you ask for extra lubricating drops though as you will get through alot, keep them by your bedside for when you first wake up.
