PRK and LASEK VISION CORRECTION

PRK and LASEK – Advanced Vision Correction Options

Photorefractive Keratectomy (PRK) and Laser-Assisted Sub-Epithelial Keratectomy (LASEK) are safe and effective laser vision correction procedures designed to reduce or eliminate the need for glasses or contact lenses.

These procedures are excellent alternatives to LASIK for patients who may not be ideal candidates for flap-based surgeries due to thin corneas, dry eyes, or other anatomical considerations.

What Are PRK and LASEK?

  • PRK was the first type of laser eye surgery, introduced in 1987, and remains a trusted option for vision correction.
  • LASEK, introduced in 1996, is a variation of PRK that preserves and replaces the top layer of the cornea rather than discarding it.

Both procedures work by reshaping the cornea using an excimer laser, correcting vision issues such as nearsightedness, farsightedness, and astigmatism.

How Do PRK and LASEK Work?

  1. Removal or repositioning of the corneal epithelium (the outermost layer of the eye).
  2. A precise excimer laser then reshapes the corneal stroma beneath the surface to correct vision.
  3. The epithelium is either discarded (PRK) or gently replaced (LASEK).
  4. The eye naturally regenerates the outer layer within a few days, with vision improving over time.

A high-speed tracking system monitors and adjusts to your eye movements during the procedure, ensuring pinpoint accuracy and safety.

PRK vs. LASIK – What’s the Difference?

Feature PRK / LASEK LASIK
Flap Creation No Yes
Best for Thin corneas, athletes, dry eyes Standard candidates
Recovery Time Slightly longer (a few days to a week) Rapid (1–2 days)
Visual Outcome Excellent Excellent

What to Expect After PRK or LASEK

  • Mild discomfort for a few days as the corneal surface heals
  • Gradual improvement in vision over 1–2 weeks
  • Eye drops and a soft contact lens bandage to aid healing

Most patients achieve 20/20 vision or better once fully healed.

Is PRK or LASEK Right for You?

These procedures may be ideal if you:

  • Have thin or irregular corneas
  • Have dry eye syndrome
  • Are in a profession or sport where a corneal flap from LASIK could be a concern
