I bought this and the Systane Nighttime Lubricant Eye Ointment and have flip flopped between the two for about a week or two now. I think they're about the same honestly. I know they have slightly different ratios of mineral oil / petrolatum content, but if I were to do a "blind taste test" where I didn't know which ointment you were giving me, I wouldn't have the slightest clue which one I was using. Either way, my eyes aren't as dry when I wake up and I don't have to keep a bunch of eye drops next to my bed anymore. I used to have to reach for a whole vial or two of drops as soon as I woke up. Now I maybe use a drop or two if I really feel like it. Both of the ointments are good. If I notice a difference later on I'll update both of my reviews.

I have reached the point where I can’t use any drops/gels/ointments with any preservatives whatsoever, and so Retaine PM seems to be one of only two options left for me if I need something more viscous than drops.

It does soothe my irritated eyes; however, in times when my chronic conjunctivitis acts up or I have an allergic reaction to something it can make everything worse (maybe because it’s so thick the lids/eyes just can’t tolerate that pressure when so irritated?).

I dislike ointments because they seem so dang hard to get into the spot where I need them to go, but at least this is an option and it does work.

I used to use TheraTear gels but have found that they are making my eyes feel more gritty/sandy so I tried the Retaine PM Nighttime Ointment. The ointment isn't as easy to apply as a gel drop so there is a learning curve there. The ointment doesn't feel like a liquid bath for my eyes and doesn't remove all of my dry eye symptoms but I do notice that I have more tear flow during the day after I use the ointment so something must be working. It is worth a try if you are still struggling.

This product is not only very good, but the price is excellent. An all-round good buy.
