If you live with myopia (nearsightedness), you know what it’s like to rely on glasses and contacts for daily clarity. But when these aids become frustrating or fail to meet your needs, exploring laser eye surgery can be the next logical step. While LASIK can correct myopia and has provided clinically proven results for millions of Americans, determining if this procedure is right for your eyes requires understanding its capabilities and limitations. At Corsini Laser Eye Center, our team can help you determine if LASIK is the best option for you, or if you should consider Contoura, SMILE, PRK, or another treatment to best meet your vision goals and lifestyle needs.
Why LASIK Is Effective for Correcting Myopia
LASIK’s capacity to correct myopia lies in its ability to address the root cause of nearsightedness. Myopia occurs if your eye is slightly longer than normal, or your cornea – the eye’s clear front surface – has a steeper curvature than average. Either of these conditions causes light to focus in front of the retina rather than directly on it, resulting in blurry distance vision. Using advanced laser technology, we directly correct this underlying issue through a remarkably precise corneal reshaping process. Here’s how Dr. Corsini’s LASIK procedure restores your clear, sharp eyesight:
- During the surgery, we use a specialized femtosecond laser to create a thin, hinged flap on your cornea’s surface and gently lift it to expose the inner corneal tissue.
- We then use an excimer laser to remove microscopic amounts of inner corneal tissue, reshaping the curvature with remarkable accuracy.
- By adjusting the cornea in this targeted way, Dr. Corsini can redirect the path of incoming light, ensuring it focuses images directly on your retina for crisp, clear-distance vision.
The results of this personalized corneal reshaping are exceptional, with over 90% of our LASIK patients achieving 20/20 vision or better, and nearly all patients reaching at least 20/40, which is legal driving vision in most states. LASIK is proven to be highly safe, and its excellent track record has been demonstrated through decades of clinical studies. In fact, LASIK is the most studied surgery in the history of the world! Over 95% of LASIK patients report significant improvements in their daily lives and would enthusiastically recommend LASIK to family and friends. Of course, no surgery is without risk, and not everybody is an ideal candidate for LASIK. You should consult an ophthalmologist to determine your candidacy for LASIK or other myopia treatment options.
How Much Myopia Can LASIK Correct?
LASIK is highly effective for mild to moderate myopia (up to -6.00 diopters), with advanced technology now extending benefits to patients with higher prescriptions. Dr. Corsini’s military precision techniques, combined with our state-of-the-art equipment, allow us to address a broad spectrum of myopia severities confidently.
LASIK Outcomes by Myopia Severity
| Your Myopia Level | Typical Success Rate (Within 0.5D of Target) |
| Low myopia in the range of -1.00 to -3.00 D | 93.5% |
| Moderate level of myopia in the range of -3.00 to -6.00 D | 86.6% |
| High level of myopia in the range of -6.00 to -11.5 D | 75% |

While the effectiveness of LASIK in correcting myopia correlates directly with prescription strength—patients with lower corrections achieve the most predictable results—our commitment to technological excellence means that even those with substantial myopia often experience transformative vision improvement through customized treatment.
When Should You Consider Alternatives to LASIK for Myopia Correction?
While LASIK is a popular choice for many patients, it may not be the best fit for everyone. Factors that may make LASIK less suitable include:
- Very High Myopia.
If you have very high myopia, your cornea may not be thick enough to undergo the full LASIK treatment needed to treat your high prescription. Such patients may qualify for SMILE or be better candidates for ICL (Implantable Collamer Lens), where your surgeon implants a contact lens inside your eye instead of reshaping your cornea.
- Thin or Irregular Corneas.
LASIK requires a specific corneal thickness to safely create a flap and reshape the tissue underneath. If your corneas are too thin or have irregularities (such as keratoconus), PRK, ICL, or no surgery may be a better option. Some patients with irregular corneas benefit from a more custom treatment, like Contoura, to most accurately treat their unique corneal shape.
- Active Eye Conditions.
Conditions like severe dry eye, corneal scarring, or certain autoimmune diseases can affect healing and outcomes, making LASIK less advisable. Such patients may qualify for ICL or be advised to avoid all eye surgeries until their conditions improve.
- Unstable Prescription.
To avoid performing surgery on a moving target, patients should not undergo any refractive surgery until their prescription stabilizes for at least 6 months. Most patients’ prescriptions stabilize when their eyes finish changing shape in their early twenties. However, pregnant or nursing mothers are also advised to delay surgery to ensure their prescription remains stable during times of hormonal fluctuation.
- Lifestyle Considerations.
If you are someone with an active lifestyle or a job with increased eye trauma risk (e.g., military, first responders, athletes), then procedures without a corneal flap, like PRK or SMILE, may be better for you.
Studies show that LASIK, Contoura, SMILE, PRK, and ICL offer high rates of visual improvement and safety for suitable candidates, with similar satisfaction and effectiveness for most prescriptions.
