I just post this as 13 years ago had lasik with really bad eyes. -12 in the left and -13 in the right eye. 57 seconds under the laser. Could drive home the next day no contacts needed that is all I ever used glasses would not work. 3 months later I was perfect the right eye a fuzzy 20/20 and a bit over-corrected in the left 20/30. Could see 20/25 basically what I saw in the contacts. So today routine eye appointment and things look good. Now at almost 53 I see 20/20 or close in the left eye and 20/40 in the right. In effect I now use my right eye for close work and the left for distance which was not the original intent back then but so far I do not need glasses for reading. I was blessed and yes it can work
