Laser Surgery Lasik, Laser And PRK

Differences Between Lasik and PRK Explained

Both Lasik and PRK are proven methods for laser vision correction, but they cater to different patient needs:

• Lasik:

  • A thin flap is created on the cornea’s surface, which is lifted to allow the laser to reshape the tissue underneath.
  • Benefits include minimal discomfort and quicker recovery time compared to PRK.

• PRK:

  • The epithelium (outer layer of the cornea) is removed, and the laser is applied directly to the exposed surface.
  • The epithelium regenerates over time.
  • Recommended for individuals with thinner corneas or those at risk of flap complications.

While Lasik is often the preferred choice due to its swift recovery, PRK offers a safe alternative for patients who may not qualify for the procedure.

How Laser Vision Correction Works

The technology behind laser vision correction is both precise and effective:

1. Initial Mapping:

   • Advanced imaging tools create a detailed map of the cornea, identifying irregularities and guiding the laser for customized treatment.

2. Laser Reshaping:

   • A highly precise excimer laser removes microscopic layers of corneal tissue to correct refractive errors.
   • This adjustment ensures light focuses correctly on the retina, providing clear vision.

3. Post-Treatment Care:

   • Lasik allows patients to experience significant improvement in vision within 24–48 hours.
   • PRK may take slightly longer, as the corneal surface heals gradually.

Both procedures are completed in under 30 minutes and are virtually painless due to the use of numbing eye drops.
