Booking flights around LASIK cut-offs

Which comes first, the date or the flight

The date. The commonest booking mistake is a non-refundable fare bought on a Tuesday night, followed by an email to us asking what surgery dates fit inside it. Sometimes they do. Often the contact-lens cut-off or the surgeon's diary means the exam lands on day 4 and surgery on day 5 of a 7-day ticket, which leaves no room for the week-1 check and no room for a "wait a few days" answer at the exam. Confirm the surgery date with the clinic, then buy the flights around it. How much lead time that needs is in How far ahead to book LASIK in Colombia.

The two cut-offs

Cut-off 1: contact lenses out

This one runs backwards from the exam date. Soft lenses out one to two weeks before, toric three weeks, rigid gas-permeable a month or more, depending on the surgeon — the full table is in When to stop contact lenses before LASIK. The point for flights is that the cut-off is usually satisfied before you leave home, so it doesn't constrain your outbound date directly. What it constrains is how soon after arrival the exam can happen: if you're only just clear of the cut-off, the exam can be day 2. If you're going to be in lenses until the flight, the exam can't be for weeks and the trip doesn't work.

Cut-off 2: earliest fly-home day

This one runs forwards from surgery. Flying itself doesn't harm a healed flap — cabin pressure isn't the issue. The issues are that the surgeon wants to see you at the day-1 check and ideally at the week-1 check before you're out of reach, and that the cabin air is extremely dry at exactly the point where your eye is most vulnerable to dryness. The guidance below is what surgeons in the network typically tell patients; your own surgeon's instruction governs.

The practical reading: an 8-day trip with surgery on day 3 and the week-1 check on the morning of day 8 is the standard LASIK plan, and it's the one in The eight-day LASIK trip itinerary. If your surgeon is happy to hand the week-1 check to your home optometrist, you can fly on day 5 or 6 — some people do — but you're trading a little safety margin for two hotel nights, and we'd rather you didn't unless the trip genuinely can't stretch. PRK needs the longer window regardless, which is why a same-trip switch from LASIK to PRK, described in what happens if the exam says no, usually means moving the return flight.

Where to spend money on flexibility

Flexibility on a ticket costs money, and it's easy to buy it on the wrong half. The outbound almost never needs to move: if something changes before you leave, it changes days or weeks out and the whole trip shifts together. The return is where surprises land — a "wait and re-scan" at the exam, a switch to PRK, a day-1 check the surgeon wants to repeat, or just a slower-than-average first few days. So:

• Outbound: a basic fare is fine. Pick the one that gets you in by early afternoon the day before the exam.
• Return: either a fare class that allows date changes for a fee, or a slightly higher fare with free changes. On most US and European carriers into Colombia the difference is tens of dollars, occasionally a hundred or two. Against a $1,100–$1,800 procedure, it's the cheapest insurance you'll buy.
• Two one-ways are often the simplest way to get a rigid outbound and a flexible return without paying for flexibility on both.

Travel insurance is a separate topic and our sister site covers it. What we'll say here is that "medical postponement" is not the same as "trip cancellation," and a policy that pays out if a surgeon delays your surgery for a clinical reason is worth reading the wording for.

Arrival day

Land the day before the exam, and land early enough that you're not going straight from a red-eye into a dilated exam. Overnight flights from the US East Coast into Bogotá and Medellín arrive early morning; that's fine if the exam is the following day, and rough if it's the same afternoon. A daytime flight that lands mid-afternoon, a transfer, dinner, and a full night's sleep sets up the exam properly. Which airport is in Medellín vs Bogotá for a LASIK trip; for either, the transfer is under an hour and we can arrange it.

Departure day

The week-1 check is short — fifteen to thirty minutes — and clinics will usually give you a first-of-the-morning slot if you tell them you're flying. Build the day as: check at 8 or 9, back to the hotel to collect bags, airport by early afternoon, flight late afternoon or evening. Don't book a 10am departure and hope the check can be squeezed in at 6; it can't. If the only sensible flight home is a morning one, make the check the afternoon before and fly the next morning — that's one extra night and it's the right call.

The cabin

Aircraft cabin humidity is very low, well below what any post-LASIK eye enjoys. On a four- to ten-hour flight in the first week or two after surgery, the plan is simple and everyone forgets it:

• Preservative-free lubricating drops in your hand luggage, single-dose vials, and use them roughly every hour whether you feel dry or not. The clinic will have given you a brand; single-dose vials pass airport liquid rules without argument.
• Sunglasses on board. Window seats over a cloud deck are brutal for a light-sensitive eye.
• No screens for the first flight if you can bear it — audio instead. Screens reduce blink rate, which dries the eye further.
• Sleep with the shields if you're still in the window where the surgeon told you to wear them at night. On a red-eye home, that's likely.
• Water, not alcohol. The obvious one.

If you're flying home on day 5 or 6 rather than day 8, be stricter about all of it.

Red-eyes and connections

Outbound red-eyes are fine if you're arriving the day before the exam. Return red-eyes are fine after the week-1 check, with the shields-and-drops plan above. What to avoid is a return itinerary with a long connection in a dry, bright terminal on day 3 or 4 post-op — a six-hour layover at a hub is a worse environment than the flight itself. If the choice is a nonstop that requires an extra hotel night versus a connection that leaves a day earlier, take the nonstop.

Domestic hops

If you're combining the LASIK city with elsewhere in Colombia — Cartagena is the usual one — put the beach before the surgery, not after. A domestic flight in the first days post-op is more cabin-dry time on a fresh eye, and Cartagena's sun, sand, sea, and pool are all on the first-week avoid list. Fly in to the coast, enjoy it, take the domestic hop to Medellín or Bogotá the day before the exam, and go home from there. Same logic as the dental sequencing: the thing that's hard on the eye goes first.

Combining with dental

If you're doing dental work on the same trip, the dental days come first and add three to five days to the stay, which changes nothing about the flight rules except the return date. The full sequence is in LASIK and dental on one trip.
