Hi Lynnie, I have very dry eyes from a medical condition and what’s helped me the most is Systane Nighttime Ointment. It’s an over the counter med, no prescription.
It’s a thicker gel that gets applied inside the lower eyelid at night right before going to sleep.
It’s made a huge difference in my eyes to the point where i don’t even need eye drops during the day anymore. This lubricant keeps my eyes hydrated.

To apply I pull out my lower lid a little and squirt a strip about 1/2 long inside. Then let the ointment warm up to melt and spread over the eye. It’s a little messy if you get too much, so you’ll want to wipe the excess from the outside of your eye lid before sleeping. It also makes your vision blurry so again, just apply and go to bed. (Blurriness disappears by blinking)

Initially I was disappointed because it wasn’t consistent. Well, I found out I wasn’t consistent. LOL. Now I use it faithfully every night and have been over a year. It’s awesome! So you might want to give it a try.

I’d ask a pharmacist if it can be used with Restasis though.

Hi Lynnie, Systane Ultra and Genteal gel for severe dry eye really help my dry eye and often there are coupons! Remember, if you use it a lot, alternate with Systane preservative free so you don't get a build up in your eye. Warm compresses help a lot too. I also use OCuSoft lit scrubs to wash my lids twice a day and then I use cosmetic rounds to rinse my lids. Systane runs about $21 for the 2 vial box and Genteal is $9.99. OCuSOFT is $10.99 for 30 wipes and the cosmetic rounds are $1.29 for 100. Maintenance is a pain but it prevents problems. I hope this helped. Joan
