I cannot recommend LASIK at Wimpole Eye Clinic enough. I had surgery in April 2021, with a prescription of -6.5 in both eyes with a slight astigmatism, and within 3 days my eyesight was better than 20/20 and better than the Royal Air Force's standard.
I had my consultation within a week from the first call, and then my surgery within a month.
Overall, my experience has been extremely pleasant, quick, and life-changing.
