PRK or LASIK: how the procedure changes the trip you book

Two procedures, one laser, very different first week

LASIK and PRK use the same family of excimer laser to reshape the cornea. What separates them is the route in. In LASIK the surgeon creates a thin hinged flap, folds it back, treats the tissue underneath, and lays the flap down again. In PRK there is no flap: the very thin outer layer of cells is removed, the laser works on the surface, and that outer layer then has to grow back on its own.

That one difference drives almost everything about how you should book. The American Academy of Ophthalmology notes that most LASIK patients can return to work and drive the day after the procedure, while PRK recovery is slower because the outer cell layer has to regrow over several days, which pushes back the return to work and driving (AAO, 2023). In trip terms, LASIK front-loads the good news. PRK makes you wait for it.

Why your exam might switch you

You usually request a procedure when you inquire, but the final call belongs to the surgeon after the pre-op measurements. The common reasons a surgeon steers someone towards a surface procedure are about the cornea itself and how you use your eyes. The FDA lists thin corneas among the risk factors a doctor should screen for, warning that reshaping a cornea that is too thin can cause serious complications, and it flags people who regularly take blows to the face in sports such as boxing, wrestling and martial arts (FDA, 2018). A flap is a structure that can, in principle, be disturbed later; no flap means nothing to dislodge.

None of this means you can predict the outcome from home. Corneal thickness, the shape of your topography and the depth of treatment your prescription needs are measured on the day. What you can do is accept that a switch is possible and book a trip that survives it.

Side-by-side: what each procedure asks of your calendar

Booking the stay

Choose a room you would not mind being stuck in

With LASIK, the hotel is mostly a place to sleep between appointments. With PRK, it may be where you spend two or three days with the curtains closed and sunglasses on indoors. That changes what matters. A quiet room, blackout curtains, a kitchen or reliable delivery, and a short taxi ride to the clinic are worth more than a view or a rooftop pool you will not be using.

Book the room with free cancellation on the last nights, or as two reservations, so you can release nights if the exam confirms LASIK. Our longer piece on booking your stay around appointments covers neighbourhood choice; the PRK-specific point is simply that comfort indoors outranks location outdoors.

Plan meals and drops for someone who cannot read labels

Post-op drop schedules can involve more than one bottle at different intervals. In the first PRK days you may find small print hard to read. Ask the clinic to write the schedule in large type or colour-code the bottles, and set phone alarms before surgery, not after. A companion who has seen the schedule explained in person is the best insurance you can bring.

Booking the flight home

This is where people lose money. A fixed, non-changeable return booked on the assumption of LASIK leaves no room for a surface procedure, a slower-than-expected first week, or a surgeon who wants one more look before you leave.

• Buy a fare you can change, or hold the return as a separate one-way you book after the exam.
• Ask the surgeon directly when they are comfortable with you flying, and take their answer over any blog's, including this one. The FDA does not publish a flying timeline for LASIK or PRK, and clinic policies differ.
• Avoid tight connections. A long layover in a quiet lounge is kinder to healing eyes than a sprint between terminals with a carry-on.
• Keep drops and the protective shield in your hand luggage, along with the clinic's written instructions.

The mechanics of fare classes and change windows are in booking flights around LASIK cut-offs.

Booking time off work

The FDA's general guidance is to plan to take a few days off work after LASIK (FDA, 2018). For PRK, plan for more, and agree in advance how you will handle it if you need it. Three practical approaches work:

1. The buffer week. Book leave through the end of the week after surgery, even if you expect LASIK. Go back early if you feel ready.
2. The soft landing. Arrange to work remotely with reduced screen time for the first days back, rather than walking straight into a full schedule.
3. The pre-agreed extension. Tell your manager now that a procedure change on exam day might add a few days, and ask what they need from you if that happens.

If your job involves driving, operating machinery, or long hours of close reading, raise that with the surgeon at the consult. It is part of how they choose the procedure, and part of when they will clear you.

The money conversation, before you fly

Ask the coordinator to quote both procedures when you request your date. Some clinics price them the same; some do not. You want to know before you are sitting dilated in the clinic. While you are at it, confirm three things in writing:

• That the enhancement policy applies equally to both procedures.
• That the post-op visits included in the price cover the longer PRK schedule.
• That the post-op medication supplied, or prescribed, covers the PRK course if you switch.

Our guide to reading a Colombian LASIK quote explains where these items usually sit on the page.

What you give up, and what you gain

Neither list is a recommendation. Both procedures carry the general risks the FDA describes for laser refractive surgery, including dry eye, night-vision symptoms such as glare and halos, and the possibility of under- or over-correction (FDA, 2018). Your surgeon's job is to weigh those against your measurements. Yours is to book a trip that does not force the decision.

Who should assume PRK from the start

Some travellers are better off booking as if PRK were the plan, not the fallback. You know your own life better than any pre-screen form does, so be honest with yourself here.

• People who fight, grapple or play rough. If you train in a combat sport or regularly take knocks to the face, expect the surgeon to bring up surface treatment. The FDA's own list of poor-candidate situations names exactly these activities.
• People who have been told their corneas are on the thin side. A previous optometrist's comment, or an old topography report, is worth sending with your inquiry so the clinic can flag it early.
• People with a demanding post-op window. If you cannot afford a slow first week at all, say so up front. The surgeon may still recommend PRK, but you will be choosing your dates with full information rather than discovering the trade-off at the consult.

For everyone else, PRK is a possibility rather than a likelihood. The booking advice is the same either way: the trip should survive whichever procedure the measurements point to.

A short pre-booking checklist

• Ask at inquiry: "Based on my records, is there a realistic chance of PRK instead of LASIK?"
• Get both procedures quoted.
• Book a stay long enough for PRK, with cancellable last nights.
• Book a changeable return or hold the return until after the exam.
• Arrange leave with a built-in extension.
• Brief your companion on both recovery patterns.
• Pack for comfort indoors: sunglasses, audiobooks, easy meals.

If the exam rules out both, that is a different conversation; we cover it in what happens if the exam says no.
