Choosing the Right Vision Correction: LASIK or PRK?

Updated: Nov 26, 2023

The world of vision correction has seen significant advancements in recent years, providing patients with more options than ever to achieve clear, glasses-free vision. Two popular procedures, LASIK and PRK, have emerged as effective methods for addressing refractive errors like myopia, hyperopia, and astigmatism. In this blog post, we'll explore the key differences between these procedures to help you make an informed decision about the best option for your visual needs.

LASIK (Laser-Assisted In Situ Keratomileusis)

LASIK is one of the most well-known and widely practiced refractive surgeries globally. It has been used for over two decades and remains a top choice for vision correction.ose of cataracts, including blurry vision, glare, and difficulty seeing fine details.


  • A thin flap is created on the cornea.

  • The cornea is reshaped with an excimer laser to correct the refractive error.

  • The flap is repositioned, acting as a natural bandage.


  • Quick recovery, with most patients experiencing improved vision within a day.

  • Minimal discomfort during and after the procedure.

  • High success rate and minimal risk of haze or scarring.

Suitable for:

  • Individuals with mild to moderate myopia, hyperopia, and astigmatism.

  • Those looking for fast visual recovery.

PRK (Photorefractive Keratectomy)

PRK is the original refractive surgery procedure that has experienced a resurgence in popularity, particularly for patients with certain corneal characteristics or unique circumstances.


  • The outer layer of the cornea (epithelium) is removed.

  • The underlying cornea is reshaped with an excimer laser.

  • The epithelium regenerates in the days following the procedure.


  • Suitable for individuals with thin corneas or irregular corneal shapes.

  • Reduced risk of complications related to corneal flaps.

  • Eliminates concerns about flap dislocation.

Suitable for:

  • Individuals with mild to moderate refractive errors.

  • Those with specific corneal characteristics or preferences.

Key Differences:

Corneal Flap: LASIK involves creating a corneal flap, while PRK does not. This impacts the healing process and potential complications.

Recovery Time: LASIK typically offers the fastest visual recovery, while PRK may require a longer healing period due to epithelial regeneration.

Corneal Thickness: PRK can be suitable for individuals with thinner corneas, who may not be ideal candidates for LASIK.


The choice between LASIK and PRK should be based on your specific visual needs, eye health, and preferences. To make an informed decision, consult with an experienced refractive surgeon who can assess your candidacy for each procedure and provide personalized recommendations. With these advanced vision correction options, achieving clear, glasses-free vision is within reach.
