Many people who could benefit from LASIK never pursue it. Not because they aren’t candidates, not because of cost, but because something they heard or read convinced them it wasn’t worth the risk.
While it’s true that a very small number of patients experience negative outcomes, the internet is full of alarming stories that mix up side effects with complications and leave out the context that would make those numbers meaningful. If you’ve been on the fence about laser vision correction, it’s worth taking a closer look at what’s actually true.
At Clear Vision San Antonio, we want you to have the facts so you can decide for yourself. Keep reading to learn which LASIK myths are most likely standing between you and a life with clear, glasses-free vision.
Myth 1: LASIK Is Too Risky
This is one of the most persistent LASIK myths, and it’s also one of the most misleading. People often point to online stories or alarming statistics without recognizing that many of those numbers are taken out of context, or that they’re conflating minor, temporary side effects with serious complications. These are two very different things.
Side effects are common after any medical procedure and typically resolve during healing. For LASIK, some patients experience temporary dry eye, glare, or halos in the weeks after surgery.
Complications, by contrast, are far rarer events that require additional treatment, such as a flap dislocation or an infection. The rate of serious, sight-threatening LASIK complications is less than 1 percent, according to published ophthalmic research.
The broader picture is just as reassuring. There are more than 7,000 peer-reviewed clinical studies documenting LASIK’s safety and outcomes. More than 40 million procedures have been performed worldwide, and patient satisfaction consistently exceeds 96 percent.
The U.S. Food and Drug Administration first approved LASIK nearly 30 years ago and has continued to affirm its safety record ever since. These numbers reflect a procedure that has been thoroughly studied and trusted by patients and eye doctors alike.
Myth 2: LASIK Results Don’t Last
Some people believe that LASIK “wears off” after a few years, leaving them right back where they started. This misunderstanding is worth clarifying: LASIK permanently changes the shape of your cornea. The laser reshapes the corneal tissue itself, and that structural change does not reverse over time.
What can eventually change with age is the natural lens inside your eye, not the cornea. Presbyopia, the gradual loss of near focus that some people experience in their 40s and 50s, is a completely separate process driven by aging.
In other words, LASIK delivers permanent vision correction for the refractive errors it treats. Long-term data continues to support this, with the majority of patients maintaining their improved vision for decades after surgery.
Myth 3: LASIK Is Painful
Fear of eye surgery is understandable. The idea of a laser near your eyes is unsettling for many people. But the actual LASIK experience is much easier than most people imagine.
Before the procedure begins, numbing eye drops are applied to the eye to reduce pain. Patients typically report mild pressure during the brief moment the corneal flap is created, but no pain.
The entire laser treatment takes less than five minutes per eye. Most patients are surprised by how fast and manageable the experience actually is. Mild discomfort or sensitivity in the hours after surgery is normal and short-lived, and any post-operative tenderness generally resolves quickly with rest.
Myth 4: Most People Aren’t Good Candidates
Some people talk themselves out of a LASIK consultation, assuming they probably won’t qualify. While LASIK isn’t right for everyone, a large proportion of people who wear glasses or contacts are eligible candidates.
Candidacy is typically determined by factors such as age, prescription stability, corneal thickness, and overall eye health. Adults with nearsightedness, farsightedness, or astigmatism whose prescriptions have been stable for at least 1 year are often good candidates. A thorough consultation with a refractive surgeon is the only reliable way to find out where you stand.
For those who aren’t candidates for LASIK, that isn’t the end of the road. Procedures like PRK and RLE are designed for patients with different eye profiles and can deliver comparable results.

Myth 5: LASIK Has a High Side Effect Rate
This myth largely stems from a widely misreported FDA study known as the PROWL study. News outlets picked up the findings and reported that 45 percent of LASIK patients experienced visual symptoms.
That figure spread quickly online, and it’s still being repeated today. The Refractive Surgery Council emphasizes that it’s simply not an accurate representation of what the study found.
The PROWL study was designed to test a patient questionnaire, not to evaluate clinical outcomes. The statistic that made headlines came from a small subgroup within the study population, not from the study group as a whole.
When the data is correctly interpreted, the percentage of all study participants who reported new symptoms was between five and 10 percent. And over time, within six months, that number decreased further.
The clinical picture for LASIK side effects is manageable. Up to 30 percent of patients may experience dry eye symptoms in the first three months, which is a normal part of healing.
Fewer than five percent may need glasses, contacts, or a LASIK enhancement to address any residual prescription. For those who do experience persistent symptoms such as glare or halos, effective treatments are available. Serious complications affect fewer than one percent of patients.
Myth 6: You Could Go Blind From LASIK
This fear comes up often, and it deserves a direct response: there is no documented case in which LASIK was the primary cause of blindness. With millions of procedures performed, that record holds.
By comparison, wearing contact lenses over a lifetime carries its own meaningful risk of serious eye infection, some of which can result in permanent vision damage. LASIK, when performed by a qualified surgeon on an appropriate candidate, has a strong safety record that withstands scrutiny across decades of research and clinical data.
Your Clear Vision Starts With a Consultation
LASIK myths are everywhere, and they’re convincing enough to keep genuinely good candidates in glasses or contacts for years longer than necessary. The clinical evidence tells a different story: LASIK is safe, effective, permanent, and well-tolerated by the vast majority of patients who undergo it.
