You were told wrong. It takes minimum of 6-8 weeks for the cornea to heal as strong as before. You should use artificial tears 4-6 times/day and a lubricating gel at bedtime (such as Genteal Gel). Failure to do so could cause 'recurrent corneal erosion syndrome) If you vision is not back to normal by then you need to see an corneal specialist Eye MD ophthalmologist. Also avoid sleeping under fan or having air blow into eye (e.g. AC unit on your car)
Your problems are very common and if you take the time to look using the search feature there are many posts similiar to yours. As long as the biomicroscope (slit lamp) exam showed continued healing I would probably not get corneal topography until 6-8 weeks post op and then only if the vision was not clear or the patient complaining of ghosting.
It may take a while to schedule an appointment. In the first posting I suggested 6-8 weeks. So if you called now and set up something in 1-4 weeks that would make sense.
