The things that work the best for me currently are Systane Hydration PF eye drops, NuLids, Manuka Honey gel, OcuSoft lid scrubs, moving out of a dry climate, and limiting screen time. Inflammation in general causes it to flare up -- diet, lack of sleep, alcohol, stress, staying up late coding or gaming, all seem to cause inflammation and make it worse for me.
I've also done Restasis, Xiidra, Cequa, IPL, Radio Frequency, warm compresses, and punctal plugs, without much success.
I'd like to try autologous tear serum next.
