LASEK

What is LASEK?

LASEK – or Laser Epithelial Keratomileusis – is a refractive eye surgery that combines the benefits of LASIK and PRK. LASEK can be used to treat astigmatism, nearsightedness, and farsightedness.

Similar to other forms of refractive surgery, LASEK uses an excimer laser to reshape the cornea in order to allow light entering the eye to be properly focused onto the retina. During surgery, the epithelium is treated with mild medical alcohol to detach it from the underlying tissue. The epithelial layer is then lifted back and the newly exposed tissue is re-shaped with the laser. Once the procedure is complete, the epithelium is placed back over the cornea.

LASEK Surgery Results

LASEK results are similar to the outcome of LASIK surgery. Nearly all patients achieve a minimum of 20/40 vision after the procedure, with a majority of those patients achieving 20/20 vision. Depending on your degree of refractive error, you may still need to wear glasses or contact lenses following your LASEK surgery, but the prescription will be significantly lower.

BENEFITS OF LASEK :

  • Complication associated with creating & reattaching the flap in cornea are avoided.
  • It gives less dry eyes than Lasik.

DISADVANTAGES OF LASEK:

  • LASEK recovery time is longer than LASIK. Many LASEK patients do not fully recover functional vision for 2-4 weeks.
  • LASEK recovery requires topical steroid drops and a bandage contact lens for 3-5 days after surgery.
  • LASEK is slightly more painful than LASIK.
