Swollen Corneas one week out...

At my one week post op visit, my vision was at 20/30 and the dr told me my corneas were still quite swollen. He said its not uncommon, people heal differently. I was instructed to use the prednisone drops for another 3 weeks until my next visit. My vision definitely fluctuates, and I do have some halos and glare. Sometimes I dont even notice it and other times its really annoying. No pain or discomfort or dryness - but i'm just concerned about the swelling. Any one else have swelling that lasted a while? if so - how long for it to subside and did things inprove when it did? Thanks!
ps - i went from 20/600 to 20/30 so I feel like i shouldnt even be complaining but I want that sharpness back that I had w/ glasses/contacts.
