STB I seriously considered having laser surgery last year, I have mild presmyopia. I found this website Lasik Eyes useful. Ratings on clinics, forums on specific issues and explanations of the different procedures and technology involved. I had consultations at Focus Clinics in Wimpole St, Optical Express in Shaftesbury Avenue and Moorfields. Of those clinics, OE were the cheapest and don't charge for a consultation but I felt Moorfields, although more expensive would've been a safer bet if I'd opted for treatment. There is a lot of hard sell going on and each clinic claims to have the best laser and the most innovative procedures. You have to cut through the crap a bit. In the end I decided against it because I felt the technology still wasn't advanced enough, there's no guarantee of success, each clinic offers a different solution and I didn't want to have an op which couldn't be reversed. Good luck.
