salty drops for my eyes now

I had another appointment on Thursday afternoon. They checked my eyes and they still looked OK, no ingrowth happening under the flaps like before. They went ahead and took out the bandaid contacts and had me keep using my antibiotic and steroid drop through Sunday (but my antibiotic won't last that long... I have maybe half a dose or one dose left), and they also told me to go get another type of drop from the pharmacy. It is an OTC drop and is salty... 5%. They want me to put this in my eyes four times a day until they see me again in 2 weeks. They said it would draw the moisture out from under the flaps and help them stick very closely to my eyes and help prevent those cells from growing under again. It feels like I am putting ocean water in my eyes when I use them. But it only burns for half a minute or so and then it is OK. Right now it feels like I have an eyelash in my left eye but my right eye feels completely normal. I won't give any more LASIK updates until after my next appointment. I am still seeing fine to work, read, drive, etc.
