text: are there any precautions one must take after having undergone lasik?   any kind of surgery requires any precautions. the best ones are to follow your surgeon's and doctor's orders. never take you friends advice, because not everyone goes through the same kind of surgeries. and remember, just because a friend of yours went through lasik, and it went fabulous for her or him, does not necessarily mean that they did not take any precautions. if you see something unusual, consult your physician. thank you.
