LASIK has been performed for decades and studied in hundreds of clinical papers — yet it remains one of the most misunderstood procedures in modern medicine. Ask around and you’ll hear that LASIK is agonizing, that the results “wear off,” or that it’s some risky experiment. Almost none of it holds up.
Misinformation stops a lot of people from even exploring a procedure that could genuinely change their daily life. So let’s clear the air. Here are ten of the most persistent LASIK myths, and the reality behind each one, so you can weigh the decision on facts rather than fears.
Myth 1: “LASIK is painful”
Reality: For the vast majority of patients, LASIK is not painful. Before the procedure begins, your surgeon applies numbing drops that make the eye insensitive to pain. During treatment you may feel pressure and be aware of what’s happening, but not sharp pain. Afterward, it’s common to feel mild irritation — like an eyelash in the eye — for a few hours, along with some watering and light sensitivity. That settles quickly, usually after a good nap. Compared with the discomfort most people imagine, the real experience is surprisingly gentle especially if you are using the latest technology available at Clarity Laser Vision like the Zeiss visumax 800 which applies very little pressure to the eye. Our LASIK recovery timeline walks through exactly how those first hours feel.
Myth 2: “The results wear off after a few years”
Reality: LASIK permanently reshapes the cornea, so the correction it makes doesn’t simply “wear off.” What can happen is that your eyes continue to age naturally — most people eventually need reading glasses in their forties and fifties regardless of whether they’ve had LASIK, because of a separate age-related change called presbyopia. That’s not LASIK failing; it’s biology continuing. A small number of patients experience some regression and may benefit from an enhancement, which we cover in Can You Get LASIK Twice?
Myth 3: “You could go blind from LASIK”
Reality: This is perhaps the most frightening myth — and one of the least supported by evidence. LASIK reshapes the surface of the eye; it does not touch the optic nerve or the structures whose damage causes blindness. Serious, sight-threatening complications are extremely rare, especially when patients are properly screened. As with any surgery there are risks, but “going blind” is not a realistic characterization of them. The U.S. FDA’s LASIK information hub lays out the actual risk profile in plain language.
Myth 4: “LASIK is new and experimental”
Reality: LASIK is anything but new. The lasers used were approved by regulators decades ago, and the procedure has been refined continuously ever since. The American Academy of Ophthalmology notes that LASIK’s risks and benefits have been studied consistently since the FDA approved it, with more than 300 peer-reviewed studies showing that on average around 95% of patients are satisfied with their outcomes. Far from experimental, it’s one of the most-studied elective procedures in the world.
Myth 5: “LASIK only works for nearsightedness”
Reality: LASIK corrects nearsightedness, farsightedness, and astigmatism. The myth that it can’t handle astigmatism is especially common and especially wrong — modern LASIK treats astigmatism routinely within a treatable range. We tackle this directly in LASIK for Astigmatism: Does It Work? If your prescription happens to fall outside LASIK’s range, other procedures like ICL can pick up where it leaves off.
Myth 6: “You’ll smell burning during the procedure”
Reality: The excimer laser used to reshape the cornea works through a process that doesn’t “burn” tissue in the way people imagine. Some patients report a faint, distinctive odour during treatment, but there’s no burning sensation and nothing to be alarmed about. Your surgical team will tell you what to expect at each moment, which removes most of the anxiety around these sensory details.
Myth 7: “Recovery takes weeks or months”
Reality: LASIK has one of the fastest recoveries in surgery. Most patients see dramatically better by the very next morning and return to desk work within a day or two. Full stabilization of vision can take several weeks to a few months, and mild dryness is common early on, but you’re functional almost immediately. This quick turnaround is a big part of why people choose LASIK over surface procedures like PRK, which heals more gradually.
Myth 8: “LASIK is unaffordable”
Reality: LASIK is a real investment, but “unaffordable” is a stretch for most people once you account for two things. First, most Calgary clinics offer financing and monthly payment plans, sometimes interest-free for a period, so you don’t pay everything upfront. Second, LASIK replaces years — often decades — of spending on glasses, contacts, solution, and prescription sunglasses. When you run that long-term math, the numbers often look very different.

Myth 9: “Everyone gets permanent dry eye”
Reality: Temporary dryness is one of the most common LASIK side effects — but for the overwhelming majority of patients it’s exactly that: temporary. It typically improves steadily over the weeks and months after surgery and is well managed with lubricating drops. Patients who already have significant dry eye are screened carefully beforehand, and if it’s a concern, a surgeon may treat it first or recommend a procedure less associated with dryness, such as SMILE Pro. Permanent, troublesome dry eye is uncommon in well-selected patients.
Myth 10: “If LASIK isn’t right for me, I’m out of luck”
Reality: Not being a LASIK candidate is rarely a dead end — it usually just points to a better-suited procedure. Thin corneas may favour Custom PRK; high prescriptions may favour an Implantable Collamer Lens (ICL); patients over 45 may be better served by Refractive Lens Exchange (RLE) or the Light Adjustable Lens (LAL). The goal was never LASIK specifically — it’s clear vision, achieved with the right procedure for your eyes. Our complete guide to vision correction options in Calgary lays them all out.
Why myths persist — and why facts matter
Most LASIK myths come from three sources: outdated information from the procedure’s earliest days, second-hand horror stories that lack context, and a natural, healthy caution about anything involving our eyes. That caution is reasonable — you should take an eye procedure seriously. But taking it seriously means getting accurate information from qualified professionals, not absorbing fear from internet comment sections.
The single best antidote to myths is a proper consultation. When you sit down with a surgeon who examines your eyes, explains your options, and gives you honest answers, the fog of misinformation lifts fast. In Canada, you can also lean on trusted authorities like the Canadian Ophthalmological Society for evidence-based eye care information.
A few more myths worth busting
Ten wasn’t quite enough — these three come up almost as often.
“You have to be awake and it’s terrifying.” You are awake, but the procedure is quick and calm. Your surgical team talks you through each step, numbing drops keep you comfortable, and many patients are surprised by how anticlimactic it feels. Anxiety beforehand is normal; the reality is usually far less dramatic than the imagination.
“LASIK ruins your night vision permanently.” Glare and halos at night are common early in recovery and typically diminish over the following weeks and months. Modern diagnostics also measure your pupil size in advance specifically to plan around nighttime vision. Lasting, troublesome night-vision problems are uncommon in well-screened patients.
“You can’t play sports or stay active after LASIK.” Quite the opposite — freedom from glasses and contacts is one of the reasons active people choose it. After a short healing period and clearance from your surgeon, most patients return to their activities, often enjoying them more than before. (Contact-sport athletes should still discuss timing and whether a flap-free option like SMILE Pro or PRK suits them better.)
The pattern across all thirteen myths is the same: most fear around LASIK comes from outdated or second-hand information, and it tends to evaporate once you get accurate answers from a qualified professional.
Frequently asked questions
Is LASIK actually safe? LASIK has a strong safety and satisfaction record when patients are carefully screened, with serious complications being rare. We cover this fully in Is LASIK Safe?
Will I really never need glasses again? Many patients no longer need glasses for daily activities, but LASIK doesn’t stop age-related changes, so reading glasses may still be needed later in life.
Does LASIK hurt during or after? Numbing drops prevent pain during the procedure. Mild irritation for a few hours afterward is normal and short-lived.
What if I’m not a candidate? You likely have excellent alternatives such as PRK, SMILE Pro, ICL, RLE, or LAL. A consultation identifies the right fit.
