What is LASIK Surgery?

LASIK (Laser-Assisted In Situ Keratomileusis) is a laser eye surgery used to correct vision problems such as nearsightedness, farsightedness, and astigmatism, aiming to reduce or eliminate the need for glasses or contact lenses.

It is one of the most common vision correction procedures worldwide and delivers accurate and fast results thanks to advanced laser technology.

How is LASIK performed?

The procedure takes just a few minutes and includes two main steps:

1. Flap Creation:
   A precise instrument called a microkeratome lifts a thin flap from the cornea.
2. Laser Reshaping:
   An excimer laser reshapes the corneal surface according to the patient's exact prescription, then the flap is repositioned.

Advantages of LASIK

• Immediate results – most patients notice improvement within 24 hours.
• Fast and painless procedure.
• No need for hospital stay.
• Quick return to daily activities.
• High precision in vision correction.

Who is a good candidate for LASIK?

• People with stable myopia, hyperopia, or astigmatism.
• 18 years or older.
• Corneas thick enough to allow flap creation.
• No chronic eye conditions like keratoconus or cataracts.
• Generally healthy and free from autoimmune diseases or chronic inflammation.

Possible Side Effects

While the procedure is safe, temporary side effects may include:

• Dry eyes.
• Slight blurriness or halos around lights.
• Light sensitivity.
• Itching or a foreign body sensation in the eye.

These symptoms typically disappear within days to weeks with proper care and prescribed drops.

LASIK vs. Femto-LASIK

• Traditional LASIK uses a mechanical blade to create the corneal flap, while Femto-LASIK uses a femtosecond laser for higher precision and safety.
• Femto-LASIK is better suited for patients with thin corneas or high prescriptions.

Post-Operative Tips

• Do not rub your eyes at all.
• Use prescribed drops regularly.
• Wear sunglasses during the first few days.
• Avoid swimming or makeup for the first week.

Conclusion

LASIK is one of the safest and most effective vision correction options and offers freedom from glasses or contacts. However, a consultation with an eye specialist is essential to determine whether it's right for your condition.
