How Soon Can You Fly After LASIK or Cataract Surgery?
Cabin pressure is not the problem after eye surgery. The next-day check and dry cabin air are. How to plan flights around LASIK, SMILE, lens exchange and cataract surgery.
- Flying does not harm routine LASIK, SMILE, lens or cataract surgery.
- Your date is set by the in-person check the day after surgery.
- Dry cabin air is the real nuisance: carry lubricating drops.
If you are travelling for eye surgery, the flight home shapes the whole trip. The short version: for routine LASIK, SMILE, lens exchange and cataract surgery, flying does not harm the eye. What decides your date is the in-person check the day after surgery.
Why altitude is not the issue
Commercial cabins are pressurised, and routine corneal and lens surgery leave no gas inside the eye. The well-known exception is retinal surgery in which a gas bubble is placed in the eye: those patients must not fly until the bubble is gone, because it expands at altitude. That is a different operation from the ones discussed here.
The exception is retinal surgery with a gas bubble in the eye. Those patients must not fly until the surgeon confirms the bubble has gone.
Why the next-day check decides
The first twenty-four hours are when the surgeon confirms that a LASIK flap is in position, that eye pressure is normal after lens surgery and that there is no sign of infection. Problems found at that visit are usually simple to fix. Found three days later and a thousand miles away, they are not. So we do not give clearance to fly before that check, and we give it in writing.
Dry air: the practical problem
Cabin humidity is very low, and eyes are already drier than usual after laser surgery. Carry preservative-free lubricating drops in your hand luggage and use them every half hour or so. Keep the air vent pointed away from your face, avoid sleeping with your eyes partly open against the airflow, and do not rub your eyes.

How many nights to plan
For LASIK or SMILE, three to four nights covers arrival, surgery, the next-day check and a margin. For lens exchange and cataract surgery the number depends on whether both eyes are done on this trip and how far apart, which Dr. Serrano sets at your video evaluation, before you book flights.
| Procedure | Nights to plan | Why |
|---|---|---|
| LASIK | 3 to 4 | Arrive, surgery, next-day check, margin |
| SMILE | 3 to 4 | Same check; vision sharpens over days |
| Lens exchange | Set at your evaluation | Depends on one eye or two, and the gap |
| Cataract surgery | Set at your evaluation | Each eye has its own next-day check |
On the day you travel
Wear sunglasses, keep your drops schedule going across time zones, and do not lift heavy bags after lens surgery; ask for help or check your luggage. Los Cabos International has direct flights to Seattle, Portland, San Francisco, Los Angeles, San Diego and Phoenix, which keeps the travel day short.
