Treatment for halo/ghosting years after LASIK?

Thanks for your question.  There can be several explanations for nighttime vision issues that occur even years after Lasik.  3 common explanation include: residual refractive error, dry eye disease, and higher order aberrations that impact vision when the pupil dilates in the dark.  A full visit to your ophthalmologist is necessary to determine which, if any, of these 3 explanations may be affecting you.  Simple solutions that have helped others include:  glasses to be worn during night driving, management of dry eye (which creates dry spots on the surface of the eye, worsening glare/halos), and the use of mild pupil-constricting eye drops 20 minutes before driving at night. Please follow up with your ophthalmologist to determine the right treatment for you.

You should be checked by your ophthalmologist.  There are a lot of correctable reasons for glare and haloes after LASIK including dry eye, cataract and residual error.  Sometimes night driving glasses help because we become a little more nearsighted when our pupils enlarge at night.  Polarized lenses can help, too.
