LASIK eye surgery may be the life-changing solution you’ve been looking for if you’ve been living with glasses or contact lenses due to nearsightedness, farsightedness, or astigmatism. But just how effective is LASIK? Let’s break down what you need to know.
What Is LASIK Eye Surgery?
LASIK (Laser-Assisted In Situ Keratomileusis) is a type of refractive surgery designed to correct vision problems caused by refractive errors. A refractive error occurs when the shape of your eye prevents light from focusing properly on the retina. This leads to blurry vision.
During LASIK, a laser is used to reshape the cornea—the clear front surface of the eye—so light entering the eye is properly focused onto the retina. This improves how your eyes process images and can significantly reduce, or even eliminate, the need for corrective lenses.
LASIK can effectively treat myopia (nearsightedness), hyperopia (farsightedness) and astigmatism.
How Effective Is LASIK?
LASIK eye surgery has a proven track record of high success. The vast majority of patients experience dramatic improvements in their vision. According to national data, around 90% of LASIK patients achieve 20/20 to 20/40 vision without glasses or contacts.
Most patients see improvements within hours to days of the procedure, and many are able to return to their normal routines the very next day. It’s a fast, safe, and effective outpatient procedure with minimal downtime.
In most cases, the results of LASIK are long-lasting. Once the cornea has been reshaped, it typically stays that way for life. Many patients enjoy clear, stable vision for decades after their procedure.
However, it’s important to remember that LASIK doesn’t stop the natural aging process. Around age 40, most people develop presbyopia, a condition that affects near vision. This is not caused by refractive errors and cannot be corrected with LASIK.
To address presbyopia, some patients choose a monovision LASIK approach—where one eye is corrected for distance vision and the other for close-up tasks. This option works well for some but may take time to adjust to. Trying monovision with contact lenses beforehand can help determine if it’s right for you.
Who Is a Good Candidate for LASIK Surgery?
LASIK is a great option for many, but not everyone is an ideal candidate. To have LASIK surgery, you need to meet certain requirements. Here are some of them:
- You should be 18 years or older (ideally, over 21 years old, when vision is more likely to have stopped changing).
- Your eye prescription should not have changed much in the last year.
- Your refractive error must be one that can be treated with LASIK.
- Your corneas need to be thick enough and healthy, and your overall eye health must be generally good.
- You need to have realistic expectations about what LASIK can and cannot do for you.
Some people are not candidates for LASIK. They include people with:
- an unstable (changing) refractive error
- extreme levels of myopia, hyperopia or astigmatism
- severe dry eye
- corneas that are too thin
- corneal scars or disease
- keratoconus(cone-shaped cornea)
- advanced glaucoma
- a cataract affecting vision
- a history of having certain eye infections
- diabetes that is not controlled well
Also, women who are pregnant or breastfeeding should not have LASIK. This is due to vision changes that can happen during pregnancy. Your doctor will talk with you about other conditions that may keep you from having LASIK.
