I had lasik 3 years ago with amazing results (20/10 vision in both eyes and reduced glare/blurring from illuminated signage).

a year later I was in a pretty bad car accident & hit my head on the window before the airbags deployed sustaining permanent nerve damage in my neck, shoulders & arms. I suffer from severe migraines now & attributed the blurriness of my vision to them. My vision is now blurry even when I am migraine free. I have trouble reading the white board & switching focus without discomfort (like notebook to whiteboard etc). Is it possible to correct this with a revision of my proceedure?
