Booking LASIK or PRK in Colombia: Why Candidacy Comes Before the Flight

Why refractive surgery is a candidacy-first booking

For most procedures, a remote review of good records gets you close to a final plan. Laser vision correction is different. The decisive information comes from measuring and mapping your eyes, and that only happens in the exam room. The American Academy of Ophthalmology (2024) describes the pre-surgery evaluation: testing your vision and refractive error, checking for problems such as dry eye, and mapping the cornea, including its thickness.

Until that exam is done, any quote is a quote for a procedure you might not get. The surgeon may recommend LASIK, a surface procedure such as PRK, a different approach entirely, or no surgery. A good booking plan is built to absorb each of those answers.

The contact lens rule that shapes your timeline

If you wear contact lenses, they affect your trip dates before you board a plane. The FDA (content current 2018) advises switching to glasses full-time before the baseline evaluation, because lenses change the shape of the cornea. Its guidance is:

• Soft lenses: stop 2 weeks before the evaluation.
• Toric soft or rigid gas permeable lenses: stop at least 3 weeks before.
• Hard lenses: stop at least 4 weeks before.

The FDA adds that rigid or hard lens wearers may need measurements repeated at least a week after the first evaluation, to confirm the cornea has settled. For a traveller, that is the difference between a two-visit plan and a three-visit plan. Ask the clinic which rule it follows for your lens type, then count backwards from your screening date.

What can rule you out, or change the procedure

Ask for the clinic's screening criteria before you book anything you can't cancel. The FDA's page on when LASIK is not for you (2018) lists situations where a person is probably not a good candidate. They include:

• A change in glasses or contact lens prescription within the past year.
• Pregnancy or breastfeeding, hormone fluctuations from conditions such as diabetes, or medications that can make vision fluctuate.
• Conditions or medications that may affect healing, such as autoimmune disease, immunodeficiency, diabetes, or medications like steroids.
• Regular contact sports involving blows to the face.
• A job that restricts refractive surgery. FDA suggests checking with your employer, professional body or military service first.
• Being under 18, since no lasers are approved for LASIK below that age.

The FDA also lists risk factors the surgeon should screen for: blepharitis, large pupils, thin corneas, previous refractive surgery and dry eye. The AAO adds keratoconus, corneal scarring or disease, advanced glaucoma and cataract affecting vision among common reasons people are not candidates.

Some findings rule out LASIK but leave another option open. Others mean surgery isn't advisable. Your booking should be able to handle both.

How each screening outcome should affect the booking

Ask for this in writing before you pay. If a clinic won't separate the screening fee from the surgery deposit, ask why.

LASIK and PRK need different amounts of time in Colombia

Quotes sometimes bundle "laser eye surgery" as if every option recovered the same way. They don't. The AAO's recovery guide (2023) explains that after a flap procedure such as LASIK, most people can drive and work the next day. With PRK, the outer layer of the cornea is removed and has to regrow over a few days, so driving and work come later. Across all of these procedures, blurry or changing vision, dry eyes and glare or halos can last weeks to months. The AAO says vision is usually stable and clear at about six months.

That matters most if the screening switches you from LASIK to PRK after you arrive. Ask in advance what your stay would look like under each option, and keep enough slack in the return date to cover the longer one. Our guide to booking buffer days explains how to pad an itinerary without overpaying.

Plan the trip around the follow-up schedule

The FDA says to expect the first follow-up visit within 24 to 48 hours after surgery, then visits at regular intervals for at least six months. The early visit happens in Colombia. Most of the rest will probably happen at home, so before booking, confirm:

• Which visits the clinic needs to do in person before you fly, and when it will clear you to leave.
• Which eye doctor at home will do the later checks, and what records they will need. See handling post-op follow-up back home.
• How enhancements work if you need one. The FDA advises waiting until measurements are stable across two visits at least three months apart before any re-operation, which would usually mean another trip.

Don't plan a beach week around eye surgery

Some restrictions clash with a holiday itinerary. The FDA's general guidance is to avoid swimming pools, hot tubs and whirlpools for one to two months, to stay away from strenuous contact sports for at least four weeks, and to avoid makeup, lotions and creams around the eyes for up to two weeks. You will also need someone to take you home on surgery day, because the relaxing medication may affect your vision and judgement. If you planned to recover by the pool, change the plan before you book.

What to bring to the screening appointment

The screening is the visit that decides the trip, so treat it as the main event. Bring:

• Your current glasses, and older prescriptions if you have them. A record of a stable prescription helps.
• Records of any eye conditions, injuries, infections or previous eye surgery.
• A full medication list, including eye drops and anything for autoimmune conditions, diabetes or hormones.
• Details of your job or hobbies if either has vision standards or involves impact to the face.
• Written questions about which procedure the surgeon recommends and why, and what the alternatives are.

Ask for copies of your measurements at the end of the visit. They are useful to your home eye doctor whatever you decide.

A booking sequence that keeps candidacy first

1. Send your current prescription, prescription history and eye records for a preliminary opinion.
2. Ask for the screening criteria, the contact lens rule and the fee structure in writing.
3. Stop wearing lenses according to the clinic's instructions.
4. Book refundable or changeable travel that leaves room for repeat measurements.
5. Have the in-person screening, and only then confirm the procedure and final price.
6. Stay for the early follow-up visits and get your records before you leave.

Frequently asked questions

Can a clinic confirm I'm a LASIK candidate from my prescription alone?

No. A prescription and history can support a preliminary opinion, but candidacy depends on in-person measurements such as corneal mapping and thickness, a dry eye check and refraction. Treat any remote answer as provisional.

How long before the screening should I stop wearing contacts?

The FDA's general guidance is two weeks for soft lenses, at least three weeks for toric soft or rigid gas permeable lenses, and at least four weeks for hard lenses. Follow the clinic's own instructions, which may differ.

What if the surgeon recommends PRK instead of LASIK after the exam?

Ask for a new written quote and make sure you can decline it. PRK usually means a slower start to recovery, because the outer corneal layer has to regrow over a few days, so you may need a longer stay.

How many days should I plan to stay in Colombia?

That depends on the procedure and the clinic's follow-up plan. The FDA says the first follow-up is usually within 24 to 48 hours of surgery. Ask the surgeon which visits must happen before you fly, and allow extra time in case measurements need repeating.

Who handles follow-up after I return home?

Usually an eye doctor near you, since follow-up continues for at least six months. Arrange this before you travel, and bring home your pre-op measurements, the operative details and the post-op instructions.
