I Have Halos and Starbursts One Year After PRK. No Scarring or Haze, and 20/20 Vision Besides That. What Are my Options?

Question

I was operated with flying spot PRK and one year after the surgery I still see halos/starbursts at night. The darker it gets, the worse they are (when driving at night I see a big difference when I turn on/off the cabin light). The treatment zone was more than 9mmx8mm for one eye and 10mmx9mm for the other. My pupils do dilate easily beyond 7-8mm in low light and the starbursts/halos follow closely their reaction to more/less light.

The most common reason for glare and halos at night is that you have a small amount of residual astigmatism in your eyes.  This could theoretically be treated by doing more laser, but if you are 20/20 and able to drive at night the best course may be to leave it alone.  Dry eyes can contribute to GASH (Glare, Arcs, Streaks, Halos) and if you are not taking artificial tears this may help.   There are also drops such as Alphagan P that get rid of glare and halos, but you would have to take these drops nightly.
