Horrible distance vision. Seeing double/triple 4 months post PRK enhancement on right eye. Should I be worried?

I am seeing double / triple vision especially at night witch makes it hard to drive. When I wake in the morning my vision is much better and i'm able to see distance fairly well, but after an hour or looking at something close up my distance vision completely goes away in my right eye. The Dr. who performed my surgery claims it's just not healed yet but this is the second round on my right eye and i'm feeling discouraged as it did the same thing last time with no improvement after a year.
