The LASIK consent form: what you are actually signing

Why the form exists at all

Informed consent isn't a Colombian invention or a medical-tourism add-on. Every reputable refractive clinic in the world uses one, and the ones we book with follow the same logic as a US or UK clinic: the surgeon has to show you understood what the procedure does, what it might not do, what could go wrong, and that you chose it anyway. In Colombia, the document is also what the clinic will point to if a dispute ever reaches the Superintendencia de Salud or a civil court, so it is written carefully.

That's why the version you get is often long — six to twelve pages is normal — and why it can read as alarming. It lists things that happen to a tiny fraction of patients because the law requires that they be listed. A consent form that only mentioned dry eye and halos would be a red flag, not a comfort.

The practical problem for a travelling patient is timing. At home you'd typically get the form days ahead. On an eight-day trip, some clinics hand it over on exam day and expect a signature the next morning. That's fine if you've already read the structure below. It's not fine if the first time you see the words "corneal ectasia" is with a pen in your hand.

The sections, in the order you'll meet them

Exact wording varies clinic to clinic, but almost every Colombian refractive consent form contains the same eight blocks. Here's what each one is doing.

The risk list, read calmly

This is the part people photograph and send us at 11pm. So let's take it in one pass.

The risks fall into three tiers. The first tier is common and temporary: dry eye for weeks to months, glare and halos at night that usually fade, fluctuating vision in the first fortnight, light sensitivity. Almost every patient gets something from this tier and it is why the follow-up schedule exists. The second tier is uncommon and manageable: under-correction or over-correction needing an enhancement, epithelial ingrowth under the flap, a flap fold or striae, an infection caught early and treated with drops. These are the reasons the day-2 and week-1 checks matter. The third tier is rare and serious: corneal ectasia (progressive thinning), significant permanent loss of best-corrected vision, severe chronic dry eye. This tier is why the pre-op exam is so thorough — a good screening is designed to exclude the people at risk for it.

If your form does not mention ectasia, ask why. Every refractive surgeon knows it's the one to screen for, and its absence suggests a form that was trimmed for comfort rather than compliance.

The two clauses that are actually negotiable

Most of the document is boilerplate that no clinic will change for one patient. Two clauses are worth a conversation, and both connect straight back to the quote you accepted.

The enhancement policy

Somewhere in the "expected results" or "clinic obligations" block will be the enhancement, or retoque, policy: whether a touch-up for residual correction is included, for how long, and under what conditions. Twelve months is common; some clinics say six, a few say lifetime with conditions. Read this alongside your quote. If the quote said "enhancement included" and the form says nothing, get it added in writing before you sign. A travelling patient has to fly back for an enhancement, so knowing the window matters more for you than for a local. We cover what the quote should have said in Reading a Colombian LASIK quote.

Who operates

The form should name the surgeon. If it names a clinic or a "surgical team," ask for the individual's name and licence number to be written in. This is standard practice at the clinics we work with, and a coordinator who resists the request is telling you something.

Language and translation

You will usually be given a Spanish original and an English translation. Legally, the Spanish version is the one that governs in Colombia. That's not sinister — it's just where the clinic is — but it means the English copy should be a faithful translation rather than a summary. If the English version is noticeably shorter than the Spanish one, ask what was left out.

Some clinics include a short translator's declaration, where a bilingual staff member confirms they explained the document to you. That's a good sign. If you don't speak Spanish at all and the coordinator is the only bilingual person present, it's reasonable to ask for five minutes alone with the English copy before anyone asks you to sign.

What you should walk out with

A signed copy, physical or PDF. Not later, not "we'll email it" — at the time. You need it for three reasons: your home optometrist may want to see the procedure and technology named; your HSA, FSA, or insurer may want the consent alongside the invoice (we cover that in the itemised-invoice article); and if anything ever goes wrong, the document that describes what you agreed to is the one you want in your own folder.

Photographs and data consent

Many forms include a separate clause allowing the clinic to keep your scans and use anonymised images for teaching or marketing. It's usually a tick-box. You can decline it without affecting anything else; you should read it so you know what you've allowed. A related clause covers sharing your records with a referring party — if you booked through us, that's what lets the clinic send us your exam result and surgery confirmation so we can coordinate your follow-up. Decline that one and we can't; it's your call.

Red flags, in order of seriousness

• Blank fields for the procedure, the eye, or the surgeon's name, with a request to sign now and "we'll fill it in."
• A risk list that fits on half a page, or that omits ectasia and loss of best-corrected vision.
• A different procedure or technology from the one you were quoted.
• No enhancement policy anywhere, in the form or the quote.
• Being asked to sign before the exam results are discussed with you. Consent follows the exam, not the other way round.

None of these are common at reputable clinics. All of them are the reason you read the form rather than skimming it.

A note on what consent doesn't do

Signing does not waive your rights. In Colombia, as almost everywhere, a consent form documents that you were informed; it does not release a clinic from negligence. If someone tells you otherwise, they've misunderstood their own document. Equally, it doesn't guarantee an outcome — no form can — which is exactly why the results section talks about targets and probabilities rather than promises.

Read it once at the hotel the night before, with the question list from the consult article next to it. Bring anything unclear to the morning. Then sign, take your copy, and get on with the day.
