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.

So as you can see, those lasik eye surgery would not be very safe and would leave some negative impacts on your eyes, including nausea, because sometimes after the surgery, your eye pressure would be increased which would make your head pain and have nausea feeling. Or course it is normal, so you need to check your eyes again and take follow up measures.
