Lasik 5 weeks ago. Right eye extremely dry. Punctal plug is in, taking omega 3s, using drops hourly. Would it be worth going on restasis? Or wait?

Probably worth it. Restasis takes some time to begin to work, so it may well be a good idea to start it now. Little downside to doing so--but you should discuss this option directly with your lasik surgeon.
Post-LASIK dry eye. Restasis takes quite a while to take effect but i think it is appropriate in your situation.
Restasis. This drop will help but the effect takes weeks to feel. Restasis works better when started months before lasik. Pass this on to friends thinking about getting lasik.
