what can go wrong in laser eye surgery and how often does it go wrong?

I am assuming you mean LASIK.

Complications themselves are rare but they can happen. I don't have the actual stats in front of me right now, but I would say less than 5%.

Most complications happen because of how you take care (or don't take care) of your eyes after the surgery and usually not because of the surgery itself. You can dislocate the flap that they cut if you rub your eyes too hard (for example). The flap can dislocate up to a year after the surgery. You can get corneal infiltrates in the area where the flap was cut, in which the flap would have to be relifted by the surgeon and cleaned. You can get irregular astigmatism if the flap does not heal smoothly (if it is rubbed or whatnot). You can get dry eye because nerves that stimulate tear production are cut when the flap is made. You may need an enhancement or glasses after the surgery if the surgeon over- or under-corrected your vision. (If you are over age 40, you certainly will need reading glasses for sure)

And there's more, but I'll stop the list there.

The recovery time can be up to one full year. Granted, you will be able to see clearly within about 24 hours or less, but the flap itself may take a full year to 100% heal through and through. Most people immediately after the surgery feel like they have a grain of sand in their eye, but that usually goes away within a day.

Personally, I had LASIK 3 years ago. My surgery was about 3 PM and things were super blurry and very bright right after the surgery. Before I went to bed, I could kind of see things in the distance. The whole afternoon, my eyes just kind of felt like they had an eye ache (like a headache) but I did not feel like I had a grain of sand in them. When I woke up the next morning and saw the surgeon first thing in the morning, I could see 20/20 and was 100% pain free. The quickness of the results was amazing, and getting the surgery was one of the best decisions I ever made.

With any type of surgery where you are altering some sort of your body, there are risks no matter what. And although the complications are rare, they CAN happen. However, with LASIK, as long as you are paying attention to your eyes and keeping your regular appointments with your eye doctor for follow-ups, there is no reason that any of the complications can't be taken care of right away.

If you want more detailed information, I would suggest to you talk to your eye doctor (optometrist) and let me know you are interested in the surgery and if you would be a candidate for it. And they can also go over all of the complications with you too.

No, you can't have it at 13. If you're still young your eyes are constantly changing. You have to wait until your eyes have settled down before you can get it.
