FAA tillåter inte flygare med komplikationer som halor. etc. Från 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)...
En läkarundersökare ska intyga att sökanden (för pilot) inte lider av sådana komplikationer:
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 tillåter inte individer med fall där det kirurgiska resultatet påverkar ens ansvarsförmåga ; ha en halo effekt skulle vara en diskvalificerare.
