How should I take care of my eyes after LASIK?

How should I take care of my eyes after LASIK?

Supplements or even food and such...

Is there something that can be really helpful for the eyes?

And, what should I do to maintain my eyesight?

Once you have LASIK, if your vision worsens again afterward, it's said to be difficult to undergo the procedure again, so proper care seems to be really important.
