Most of the medications for seizure
do have ocular drying as a side effect. But generally its not very severe. Do you also have a dry mouth
and hot flushes. They will generally be seen together with the dry eyes
Most lubricating drops do not cause any burning. If your is, then maybe you are allergic to the preservatives in them. Even preservative free eye drops have a "diasppearing" preservative in them. Change the brand and see if the other is comfortable to you.
hope this helps
