Flying after LASIK is safe from 48 hours post-surgery. However, aeroplane cabin air is extremely dry (10–15% humidity) which significantly increases dry eye symptoms. Use lubricating drops very frequently during flights.
Key Facts
- Flying is permitted 48 hours after LASIK
- Cabin humidity at 10–15% dramatically worsens post-LASIK dry eye
- Long-haul flights require drops every 30–60 minutes
- Wear your UV sunglasses at the airport and during daytime flights
- Altitude does not affect LASIK flap healing
Guidelines & Tips
