I’m going to try the Miebo drops. I’m seeing my cornea specialist next month. I have relied on nightly ointment for years, but I can’t continue that. The ointment I used to use had a greater percentage of mineral oil over petroleum jelly. But, the brand has been discontinued, so I have to use the thicker ointment. It works well, but it causes my vision to be very blurry. I laid off using it and my vision returned fine. So, now I’m using Systane drops in the day. The Walgreens ointment was the best and least expensive, but it’s been out of stock a while. I wish there were other options.
