I've been using Vidisic for quite a while now. I'm using it in conjunction with Artelac drops. I use the gel for more long lasting relief. However, I find its effects a bit odd! It does prevent my eyes from drying out as much, but I need to put drops in soon after I use the gel because it causes a drying sensation, i.e. I can feel a think layer of gel on my eye surface but it feels like it needs to be diluted with drops to be more comfortable. I haven't used DuraTears, so I can't compare the two. But I wouldn't survive a day without Vidisic, it really helps. Keeping it in the fridge makes it even more refreshing I also like that the vials are resealable.
