Hi Aspan
When you see your doctor next week, ask him/her exactly what you have asked over here. You already have the right questions to ask:).
But if we talk in general terms, yes, it is possible to have overcorrections after SMILE, just as it is possible to have overcorrections or undercorrections after LASIK/PRK/ICL surgery. Usually these over/undercorrections (if any) are small, and patients still have good vision without glasses. The percentage of patients who have enough over/undercorrection to need an enhancement/adjustment is usually 1% or less. Whether this is causing your symptom or not is difficult to say here.
The only way to tell what is causing your symptom is to do a full examination, including refraction (spectacle power check), slit lamp examination, corneal topography, and so on.
Hopefully your eye problems will be successfully addressed after you see your doctor next week.
