Your doctor is correct in saying that your eyes are still healing. However, your eyes are also attempting to deal with the refractive imbalance and your work is demanding better vision.
No one can guarantee what your final outcome will be, but wearing the glasses will NOT alter your final surgical outcome. It is important to know that the glasses will put your eyes at rest when reading and in other visual activities but not disturb the surgical result.
The reason your vision is clearer some times than at other times may be based on how your visual system is dealing with the imbalance, that is, adapting. I have seen patients who are able to suppress one eye to relieve the visual strain of the imbalance, but not all patients will adapt in this way so they will be happier wearing glasses full time.
Patients who wear glasses and or contact lenses who develop changes in their prescriptions appreciate having those changes corrected with updated lenses. Frequently those changes do not affect both eyes equally, meaning that the prescription changes in one eye more than the other. Correcting the imbalance in these cases relieves the patients' symptoms and they easily understand and accept the need for different glasses or contact lenses. Refractive surgery patients are different; they expect to NOT wear glasses again so they judge, understandably, their surgical result as unsatisfactory.
