Thanks for your questions!
Post-SMILE vision fluctuation as you described could be due to several reasons which you should consider. As you correctly mentioned, it is certainly possible that you were left with residual hyperopia during the initial procedure, and after prolonged accommodation to see clearly, accommodation fatigue may have set in and hence vision becomes slightly degraded.
The second reason to consider is that of droopy eyelids. You mentioned that when you stretch your eyelids (did you mean to elevate the eyelids in an upward position?) then the vision is fully restored? If so, then ptosis, or droopy eyelids as a result of previous contact lens use, or frequent eye rubbing, or simply an ageing change is a common reason for such symptoms. I usually inform my patients of this finding at the initial consultation, and advise that after the initial surgery, they would benefit from a short procedure to elevate the eyelids in order to refresh the appearance, and make vision more comfortable in the long run.
Of course, the last and very common cause of fluctuating vision is that of dry eyes.
Do consider these suggestions, and hopefully you will be able to come to an accurate diagnosis and solution quickly!
