What is LASIK?

LASIK (Laser-Assisted In Situ Keratomileusis) is a refractive eye surgery used to correct vision problems caused by the shape of the cornea.

During LASIK:

  • A thin layer of the cornea is created.
  • An excimer laser reshapes the corneal tissue.
  • The corneal layer is repositioned.
  • Light can then focus more accurately on the retina, improving vision.

LASIK is commonly used to reduce dependence on glasses or contact lenses.

What symptoms can occur after LASIK?

Most people experience some temporary symptoms during the healing period, such as:

Dry eyes

  • Mild burning, itching, or irritation
  • Blurred or fluctuating vision
  • Increased sensitivity to light
  • Glare or halos, especially around lights at night
  • Mild discomfort or watering

These symptoms generally improve as the eyes heal, but recovery varies from person to person. Persistent or severe pain, worsening vision, significant redness, or discharge should be evaluated promptly by an eye specialist.

Why is LASIK needed?

  • Myopia (short-sightedness): Distant objects appear blurred.
  • Hyperopia (long-sightedness): Near vision may be difficult.
  • Astigmatism: Vision may appear blurred or distorted at different distances.

The main purpose is to improve unaided vision and reduce dependence on glasses or contact lenses.
