Does having a halo effect after LASIK disqualify you from being a pilot for the Air Force or commercial pilot?
FAA doesn't allow airmen with complications like halos. etc. From FAA Guide for Aviation Medical Examiners:


  The FAA expects that airmen will not resume airman duties until their treating health care professional determines that their post-operative vision has stabilized, there are no significant adverse effects or complications (such as halos, rings, haze, impaired night vision and glare)...


A medical examiner should certify that the applicant (for pilot) is not suffering from any such complications:


  An applicant treated with a refractive procedure may be issued  a medical 
  certificate by the Examiner if the applicant meets the visual acuity standards and the Report of Eye Evaluation (FAA Form 8500-7) indicates that healing is complete; visual acuity remains stable; and the applicant does not suffer sequela such as; glare intolerance, halos, rings, impaired night vision, or any other complications.  


USAF doesn't allow individuals with cases where the surgical outcome affects one's performance of duties; having a halo effect would be a disqualifier.
