How long do I have to wait to smoke marijuana? I had my LASIK eye surgery on 26-12-2017.

Shadowing can be caused by left over prescription or dryness. Since the shadowing isn't constant and appears during concentrated activities, dryness is most likely the culprit. I recommend using artificial tears four times per day. If that doesn't help, I would pay a visit to your eye doctor. 

It is still early in your healing process. Glare at night is common during LASIK recovery. Each eye may heal at a different rate. In the mean time, I recommend keeping your eyes hydrated with preservative free artificial tears because dryness may exacerbate glare. 

The most likely option for retreatment after LASIK is PRK. PRK is a different kind of laser vision correction procedure that can correct myopia. I would suggest going in for a consultation to learn about your options and to see if you are a good candidate for PRK.
