I've never had any issue with dry eyes. I started taking fish oil (algae oil actually, but the active ingredients are identical) a month before my LASIK surgery and continue to take it today, and I've still never had any problems with dry eyes, including immediately after the surgery. So, can't say whether it helped or not, but it certainly hasn't hurt.
