Medications to Disclose Before LASIK: What Your Colombian Surgeon Needs to See

If you take any regular medication, your LASIK surgeon needs to know about it before your evaluation, not halfway through. A handful of drugs can slow healing, make your prescription unstable or worsen dry eye, and a few can change whether laser surgery is advisable at all. That's not a reason to panic; most people on everyday medications can still be treated. It is a reason to send a full list early.

This guide explains which categories surgeons pay attention to and why, and how to put together a list a Colombian ophthalmologist can read quickly. It is general education. Your surgeon and the doctor who prescribes your medication are the ones who decide what applies to you.

Why medications matter for laser vision correction

LASIK, PRK and SMILE all reshape the cornea, then rely on your body to heal it smoothly. Medications can interfere at a few points.

• Healing. The U.S. Food and Drug Administration lists "conditions or medications that may affect wound healing" as a reason LASIK may not be for you, and names retinoic acid and steroids as examples.
• Stability. The FDA also flags medications that cause fluctuations in vision. Surgeons want your prescription stable before treating it.
• Tear film. Many drugs reduce tear production. Dry eye is the most common complaint after LASIK, and starting surgery with an already-dry surface makes it more likely to be bothersome. Our guide to managing dry eye after LASIK covers the recovery side.
• Interactions with post-op drops. You'll go home with antibiotic and anti-inflammatory drops. Your surgeon will want to know about anything that could interact or that you're allergic to.

Medication categories surgeons ask about

Below are the groups that most often come up in a refractive consultation. It is not a complete list, and being on one of these doesn't automatically disqualify you. It means the surgeon needs the details.

Supplements and over-the-counter products count too

People often leave these off because they don't think of them as medicine. Include them. Surgeons may ask about fish oil or other supplements in a dry-eye workup, about anything that affects bleeding, and about eye drops you use without a prescription, such as redness-relief drops, which can mask irritation.

Also mention any cosmetic eyelash serums, eyelid treatments or recent eyelid procedures. Our article on eyelid inflammation before LASIK explains why the lid margin gets attention during screening.

How to build a medication list a Colombian clinic can use

Many Colombian refractive surgeons and their coordinators read English well, but a clear, structured list saves time and avoids misunderstandings, especially with brand names that differ between countries.

1. Use generic names. Brand names vary from country to country. Write the active ingredient first, then the US or Canadian brand in parentheses.
2. Add dose, frequency and start date. "Since 2019, 20 mg daily" is far more useful than just a name.
3. Note the reason. One or two words: "acne," "seasonal allergies," "rheumatoid arthritis." The diagnosis sometimes matters more than the drug.
4. List recently stopped medications. Include anything you stopped in the past year, especially retinoids or steroids, with the stop date.
5. Include allergies and reactions. Especially to antibiotics, anesthetic drops, or preservatives in eye drops.
6. Attach recent records. If you have a condition that's relevant, a short letter or recent visit note from your doctor helps the surgeon judge whether it's controlled.

Send the list with your current glasses prescription and any prior eye records when you first ask for a quote. If you're not sure who to send it to, you can share it with us and we'll pass it to vetted surgeons for an initial read.

Questions to ask about your medications

Once the surgeon has your list, these questions help you understand the answer rather than just receiving a yes or no.

• Does anything on my list change whether I'm a candidate, or which procedure you'd recommend?
• Is there anything you'd want my prescribing doctor to weigh in on before surgery?
• Does anything here make dry eye more likely for me, and what would you do about it before and after?
• Are any of my current medications a concern alongside the post-op drops?
• If I need to pause or adjust anything, who coordinates it, and how far in advance?

When a medication changes the plan

Sometimes the honest answer is "not yet" or "not this procedure." A surgeon might suggest waiting a set period after finishing a course of treatment, treating dry eye first, or considering a surface procedure or a lens-based option instead. Our comparison of LASIK, PRK and ICL explains how those options differ.

That kind of answer is a sign of a careful clinic, not a lost sale. If a clinic never asks about medications at all, treat that as a reason to look more closely at how thorough its screening is.

The medications you'll take after surgery

It also helps to know what you'll be adding. After LASIK, most patients go home with a short course of prescription eye drops, typically an antibiotic to reduce infection risk and an anti-inflammatory (often a steroid drop), plus preservative-free artificial tears used frequently for weeks or longer. The exact drops, brands and schedule vary by surgeon and procedure. Our guide to the eye drop schedule after LASIK walks through how a typical plan is structured.

Two things are worth raising at the consult. First, if you already use any eye drops, ask how and whether to continue them alongside the new ones, and how long to wait between different drops. Second, ask what to take for discomfort in the first day. Some people assume they can use whatever pain reliever they have at home; it's better to get a clear answer from the surgeon, especially if you take blood thinners or have kidney, stomach or liver conditions that affect which pain relievers are suitable for you.

Finally, add the post-op drops to the same written list you sent before surgery, with the dates you started and stopped them. If you later see an eye doctor at home, that single page tells them exactly what you were treated with in Colombia.

Bringing your medications to Colombia

Bring enough of your regular medications for the whole trip plus a few extra days, in original labeled containers, along with a copy of your prescriptions. Keep them in your carry-on. Don't plan on refilling in Colombia: the same active ingredient may be available under a different name, but you'll want continuity during a recovery week, and some medications may need a local prescription.

Frequently asked questions

Can I get LASIK if I took isotretinoin for acne?

Possibly, but tell the surgeon the dates you started and stopped. Retinoids are associated with dry eye and are named by the FDA among medications that may affect healing, so surgeons often want a waiting period after the course ends. Your surgeon sets that timing.

Do antihistamines affect LASIK?

They don't usually rule it out, but many antihistamines can reduce tear production, which can make post-op dryness more noticeable. List them, including seasonal use, so the surgeon can factor dry eye into planning.

Should I stop my medication before LASIK?

Not on your own. Some medications are risky to stop abruptly. If a change is advisable, your eye surgeon and your prescribing doctor should agree on it and on the timing.

Do I need to list vitamins and supplements?

Yes. Include supplements, over-the-counter drops and eyelid products. They're easy to forget and occasionally relevant to dry eye or bleeding.
