I had a PRK surgery 15 months ago. I still use eye drops (Hyabuak) because I feel my eyes dry.I would like to know if I will use eye drops for all of my life. What is more, if it is logical to see better from one eye. Furthermore, sometimes I feel a little pain in my eyes. This one is appeared last 2 months. Maybe because I join in army and here the enviroment is not so clear.
