For most people, LASIK is worth it. The procedure carries a 98.7% patient satisfaction rate, over 90% of patients achieve 20/20 vision or better, and fewer than 1% experience symptoms that interfere with daily activities. At a national average cost of about $4,500 for both eyes, it eliminates years of spending on glasses, contacts, and solution. That said, the answer depends on your prescription, your expectations, and how much your current vision correction bothers you.
What the Satisfaction Numbers Actually Mean
A 98.7% satisfaction rate is unusually high for any elective surgery. That figure comes from data collected after advances in laser mapping technology became standard around 2008. Before that, satisfaction still sat at roughly 95%. The improvement reflects better screening, more precise lasers, and a clearer understanding of who makes a good candidate.
On the vision side, 99% of patients end up with better than 20/40 vision (the legal threshold for driving without glasses in most states), and more than 90% reach 20/20 or better. These numbers matter because they represent functional independence from corrective lenses for the vast majority of people who go through with the procedure.
Side Effects and Risks
The most common side effects in the first few weeks are dry eyes, light sensitivity, and visual disturbances like halos or starbursts around lights at night. For most people, these fade as the cornea heals over three to six months.
The FDA’s LASIK Quality of Life Collaboration Project (known as the PROWL studies) found that fewer than 1% of patients experienced “a lot of difficulty” with or inability to perform usual activities due to any single visual symptom after surgery. That includes starbursts, ghosting, halos, and glare. Fewer than 1% reported difficulty with daily activities due to any one symptom overall. Serious complications like corneal ectasia (a progressive bulging of the cornea) or permanent vision loss are extremely rare, though not zero.
Dry eye is the side effect that lingers longest for some patients. If you already have moderate to severe dry eye before surgery, that’s something your surgeon will evaluate carefully during screening, and it may disqualify you.
How Modern Technology Changed Outcomes
Today’s LASIK procedures typically use wavefront-guided technology, which maps the unique imperfections of your eye rather than applying a one-size-fits-all correction. Compared to conventional LASIK, wavefront-guided treatment produces a meaningful difference: 66% of eyes treated with the custom approach achieved 20/20 or better, compared to 53% with traditional methods. The custom approach also introduced fewer higher-order aberrations (the optical irregularities that cause things like halos and blurry edges). Only 16% of custom-treated eyes developed significant aberrations, versus 38% of conventionally treated eyes.
If you’re getting LASIK today at a reputable center, you’re almost certainly getting the wavefront-guided version. This is one reason outcomes and satisfaction rates have climbed so much over the past 15 years.
The Financial Calculation
The national average cost for LASIK is $4,492, or about $2,250 per eye. That’s a real number for most budgets, and insurance rarely covers it since it’s considered elective. Many practices offer financing plans.
To figure out whether it pencils out for you, add up what you spend on contacts, solution, backup glasses, and eye exams each year. For daily disposable contact lens wearers, that total often lands between $500 and $1,000 annually. At that rate, LASIK pays for itself in roughly five to nine years, with decades of glasses-free living ahead. If you wear monthly contacts and buy cheaper frames, the break-even point stretches out further. For people who simply hate the inconvenience of contacts or feel limited by glasses during sports, travel, or daily life, the value goes beyond dollars.
Who Qualifies for LASIK
Not everyone is a candidate, and a good screening process is one of the most important factors in a successful outcome. The basic requirements include a stable prescription that hasn’t changed for at least two consecutive years, adequate corneal thickness (measured during your consultation), and no active eye diseases like significant glaucoma or corneal scarring. Corneas that are too thin or irregularly shaped are a disqualifying factor because the laser needs enough tissue to safely reshape.
Age matters too. Most surgeons won’t operate on anyone under 18, and many prefer to wait until your mid-20s when prescriptions are more likely to have stabilized. On the other end, people over 40 should know that LASIK corrects distance vision but won’t prevent presbyopia, the gradual loss of near-focus that makes reading glasses necessary with age. You may still need readers after the procedure.
What Recovery Actually Looks Like
Recovery is faster than most people expect. The procedure itself takes about 15 minutes for both eyes, and many patients notice dramatically improved vision within hours. Most people can drive within 24 hours and return to work in one to three days. You’ll use medicated eye drops for a period afterward and avoid rubbing your eyes, swimming, and dusty environments for several weeks.
Vision can fluctuate during the first few weeks as your corneas heal. You might notice dryness, mild haziness, or sensitivity to bright light during this window. Complete healing and full vision stabilization typically takes three to six months, so the vision you have at one week isn’t necessarily your final result. Follow-up appointments during this period let your doctor track your progress and catch any issues early.
When LASIK May Not Be Worth It
LASIK makes the most sense for people with moderate nearsightedness, farsightedness, or astigmatism who are tired of relying on corrective lenses. It’s less clearly worth it if your prescription is very mild (and glasses don’t bother you much), if you have a very high prescription (which can reduce the likelihood of achieving full correction in one procedure), or if you have underlying conditions like autoimmune disorders that slow healing.
People whose jobs or hobbies put them at high risk for eye trauma should also weigh the small risk of flap complications, though this is less of a concern with newer surface-based procedures like PRK, which your surgeon can discuss as an alternative. And if your primary frustration is needing reading glasses after 40, LASIK for distance won’t solve that problem on its own, though some surgeons offer a “monovision” approach that corrects one eye for distance and the other for near vision.
For the roughly 99% of patients who end up with functional vision and no significant complications, the answer is straightforward: the quality-of-life improvement is substantial and lasting. The key is making sure you’re a good candidate before you ever get on the table.
