Sweat thyself not! Right eye took 15 min, including the briefing, left eye took 12. Went from 6.75/7.25 diopters to 2.75/3.15. Could have gone to near 0/0 distant, but would have lost some up-close visual clarity, which wouldn't bode well for micro electronics, model detailing, or gunsmithing. (My eyeballs are seriously distorted.) I now wear lightweight glasses instead of cokebottles and TAKE THEM OFF for close work and reading. Just wish I'd had the whole process sooner. Do it, man!Cataract surgery. Don't know how it's done but I hate anything touching my eyes including eyr drops.
