"What is LASIK?Understand Laser Vision Correction in 3 Minutes"

1. What is LASIK?

It is a surgical technology for correcting short-sightedness, long-sightedness, or astigmatism using a laser, which helps achieve clear vision without relying on glasses or contact lenses. The LASIK procedure adjusts the curvature of the cornea so that light falls perfectly onto the retina, restoring naturally clear vision. Currently, LASIK is popular worldwide because it is safe, allows for fast recovery, and provides long-term results.

2. Who is LASIK suitable for?

LASIK is suitable for individuals with short-sightedness, long-sightedness, or astigmatism that has been stable for at least 1 year, are approximately 18 years of age or older, have good eye health, and are free from complicating eye diseases such as cataracts or glaucoma. Those who are tired of wearing glasses or contact lenses can also consider LASIK to make their daily lives more convenient, whether for driving, playing sports, or working on screens.

3. Individuals Who Cannot Undergo LASIK

Although LASIK is suitable for many people, there are some groups who should not proceed, such as individuals under the age of 18, those whose vision is still unstable, those with corneas that are too thin, or those with serious eye diseases such as keratoconus, severe dry eye disease, or glaucoma. If the doctor finds a high risk after examination, it is recommended to consider alternatives to LASIK, such as PRK or ReLEx SMILE.

4. Advantages of LASIK

LASIK has many advantages, such as:

Immediate clear vision after the procedure.
Fast recovery, allowing a return to daily life within 1–2 days.
No need to rely on glasses or contact lenses anymore.
Increased confidence in daily life.
Newer LASIK technology helps reduce risks and increase precision.

5. Preparation Before LASIK

Before undergoing LASIK, you should stop wearing contact lenses for at least 3–7 days to allow the cornea to return to its natural shape. Get enough rest and refrain from using eye makeup on the day of the examination. Additionally, you should consult a specialized ophthalmologist to assess your readiness, check corneal thickness, and plan the most suitable LASIK method for each individual.

6. Care After LASIK

After the LASIK procedure, you should get enough rest, avoid rubbing your eyes or getting water in your eyes during the first week. Apply artificial tears regularly as prescribed by the doctor, and wear sunglasses when outdoors to protect against light and dust. You should attend follow-up appointments as scheduled, and if you experience abnormal symptoms such as blurred vision, eye pain, or glare, you should immediately consult an ophthalmologist.
