Why is there still some blurriness in my right eye a month after Lasik?

I have done my lasik surgery 28 days ago. My left eye vision is ok but in the right there is some blurriness. After 12 days i have checked my vision left one was 6/6 but in right there is blurring and it's .75. Doctor says to me it will become clear with time but it's still not clear as there are 4 weeks has done so will it be correct with time or not?
