I had Lasik done in India to both my eyes in 2009. The total cost came out to Rs. 25000 (~500 USD) for both eyes. I went from a 20/600 to 20/20 in 15 minutes. Best decision of my life. I made sure to get the surgery done from a highly reputed ophthalmic surgeon who had performed 1000s of surgeries with success. As in every surgery, there are side effects. For me, there was temporary mild dryness that lasted a few months, and eye drops were recommended. Besides that, there are no halos, no blurred vision, or any other visual aberrations that others report.

One thing I'm really concerned about is the flap itself. I always have the flap and eyes at the back of my mind when I play any sport. Since the flap never heals, a blow to the eyes can possibly detach the flap. I've also read instances where people who have had surgeries and swam in pools/sea water have had their flap edges infected resulting in complications. But, I am not really a swimmer, so no worries there. I went into it with as complete a knowledge as possible, and it has been worth it.
