Well, generally speaking, I have to say that it is not normal to have nausea. In common, nausea is a kind of problem which is about the stomach. So it can not occur after the lasik surgery. Besides, there are also many tips after you have taken the surgery, for after the surgery, your eyes will become sensitive and fragile. If you do not take care, it can make your eyes infected in the recovery period. For example, should be careful when you have shower. Also, you should not allow situations in which you are vulnerable to being hit in the face or the eye.
