Ocular lubricant
"I have now unfortunately had severe dry eyes I make NO tears after a horrible lasik procedure a little over 1 year ago. It is so bad that I have pretty much lost my career. I have found that Puralube helps tremendously at night I have to put a drop of walgreens brand artificial tears then apply the ointment and then put another drop in and close my eyes and that lasts about half the night and I have to put in the artificial tears and sometimes reapply the ointment throughout the night. I tried ALL the other ointments and this is the only one that relieved my eyes and let me sleep the longest at one time, also most of the others like Systane and Refresh gave me styes."
