If you’re tired of relying on glasses or contact lenses every day, you may be wondering if laser eye surgery could be the solution. LASIK is one of the most common procedures used to improve vision by correcting nearsightedness, farsightedness, and astigmatism. But how does it actually work?
What Is LASIK?
LASIK, which stands for Laser-Assisted In Situ Keratomileusis, is a type of refractive surgery that reshapes the cornea—the clear, dome-shaped surface at the front of the eye. By changing the shape of the cornea, light can focus properly on the retina, resulting in sharper vision.
For many patients, LASIK significantly reduces or even eliminates the need for glasses or contact lenses.
How Does It Work?
The clear front part of your eye is called the cornea. Think of it as your eye’s window. If its shape isn’t quite right, light won’t focus properly on the retina at the back of your eye, making your vision blurry.
Before recommending laser eye surgery, your ophthalmologist performs a comprehensive eye exam to determine whether LASIK is right for you. During this evaluation, your doctor measures your prescription, assesses the thickness and shape of your cornea, checks for dry eye, and evaluates your overall eye health. This information is used to determine if you’re a good candidate and to customize your treatment.
Once you’re approved for LASIK, the procedure follows these basic steps:
- Creating the Corneal Flap: On the day of surgery, numbing eye drops are applied to keep you comfortable. Your surgeon then creates a very thin flap in the outer layer of the cornea using advanced laser technology. The flap is gently lifted to expose the underlying corneal tissue.
- Reshaping the Cornea: An excimer laser is used to remove microscopic amounts of corneal tissue with remarkable precision. The laser treatment is customized to your unique prescription, allowing your surgeon to correct nearsightedness, farsightedness, astigmatism, or a combination of these refractive errors.
- Repositioning the Flap: Once the cornea has been reshaped, the flap is carefully returned to its original position. It naturally adheres without the need for stitches, allowing the eye to begin healing almost immediately.
The entire procedure typically takes about 30 minutes, with the laser treating each eye for less than a minute.
Does LASIK Hurt?
Many patients are surprised by how comfortable LASIK is. Thanks to numbing eye drops, you may only feel slight pressure during the procedure.
After surgery, it’s normal to experience mild irritation, watery eyes, or blurry vision for a few hours. Most patients notice improved vision by the next day, with continued healing over the following weeks.
Who Is a Good Candidate?
Not everyone is a candidate for laser eye surgery to improve vision, which is why a comprehensive eye exam is so important. In general, LASIK may be a good option if you:
- Are at least 18 years old
- Have had a stable vision prescription for at least a year
- Have healthy corneas with adequate thickness
- Do not have advanced eye diseases or certain medical conditions that affect healing
- Want to reduce your dependence on glasses or contact lenses
A personalized consultation is the best way to determine if LASIK is right for your eyes.
Why Do So Many People Choose LASIK?
People choose LASIK for many different reasons. Some want the convenience of waking up with clear vision. Others enjoy being able to play sports, travel, or spend time outdoors without worrying about glasses or contact lenses.
Some of the most common benefits include:
- Clearer vision for everyday activities
- Less dependence on glasses and contacts
- Quick outpatient procedure
- Minimal downtime
- Fast recovery for many patients
- Long-lasting results for most candidates
Every patient’s experience is unique, but many people are able to return to their normal routines within a day or two.
