Take heart that most patients will achieve relatively good vision by 1 week after ReLEx SMILE. Keep in mind that as with LASIK and PRK, ReLEx SMILE patients may experience fluctuating vision in the initial post-operative period. They often transition through a period of dry eye for several week to months. This state of dryness tends to improve gradually.
Meanwhile, be sure to be generous with your artificial tears usually provided after the surgery. Certainly if the vision is not to the level of what you expect, do ask your surgeon for his opinion as he should be monitoring your situation following surgery for signs of dryness and inflammation, both of which tend to settle with time and adequate post-operative medication.
