About 15 years ago I HAD to have Lasik. My prescription was so heavy at 7.75+1.75 on my worse eye and 7.25+1( I think?) on my good eye, that my work in autocad was suffering. Working in the Civil engineering field, I had a black background with Blue for water lines, brown for sewer, white for street center lines & property lines, etc on screen. My glasses were so thick that a white line would break up into its RGB components. A vertical line would appear to me as three too close water/power/sewer lines! I had the older physical blade type lasik. Now my vision is 20/35 but I have a LARGE number of halos, star bursts and slight double vision from headlines on cars, the stars, the moon, ect. I don't regret it as I live in Las Vegas, and there is way too much light pollution to make it viable to star gaze. I don't plan on having it touched up as I am a HEAVY reader and when I get older I want the monovision option open to me, and I will go back to glasses for the 40-60's age in my life. My doc said that due to the thickness of my corneas, I can only get 2 vision fixes until it is too thin to work on.
