Depends on the actual procedure you get done.
I had to get the PRK because I had astigmatism. After 3 or 4 days I was able to get back to work but text on my monitor was blurry and hard for me to read! I had to up the font size pretty big for about a month. PRK takes a lot longer to heal. My vision is now 20/15
My friend had the Lasik surgery the same day as me and was seeing 20/20 within 24 hours.
