LASIK vs PRK: Which Vision Correction Surgery is Right for You?
by LasikPlus

What is the difference between LASIK vs. PRK?

LASIK (Laser-Assisted In Situ Keratomileusis) and PRK (Photorefractive Keratectomy) are two popular refractive surgery procedures used to correct common vision problems like nearsightedness, farsightedness, and astigmatism. Both procedures reshape the cornea to improve vision, but they differ in their approach and recovery process.

Dr. Dean Ellis, Ophthalmologist

Understanding the procedures

LASIK involves the creation of a thin corneal flap using either a microkeratome or a femtosecond laser. The underlying corneal tissue is then reshaped with an excimer laser, and the flap is repositioned for natural healing. On the other hand, PRK involves the removal of the outer layer of the cornea (epithelium) to expose the underlying tissue, followed by corneal reshaping using an excimer laser. The epithelium naturally regenerates over time, with a protective contact bandage worn until full healing is achieved.

Procedure Differences

LASIK

  • Creates a thin flap in the cornea
  • Reshapes underlying tissue
  • Flap is repositioned to heal

PRK

  • Removes entire outer corneal layer
  • Reshapes exposed tissue
  • Outer layer regenerates naturally

LASIK & PRK Recovery

With LASIK, the recovery period is characterized by a swift improvement in vision within hours to days, with full stabilization typically occurring over a few weeks. Reports of minimal, temporary discomfort in the initial postoperative hours contribute to a generally smooth recovery process. LASIK is well-suited for correcting common refractive errors such as nearsighted, farsighted, and astigmatism, and can also address presbyopia through a technique known as monovision.

While visual recovery with PRK is slower compared to LASIK, taking a few weeks, the procedure’s full stabilization of vision may extend over a period of weeks to months. Postoperative discomfort and light sensitivity can be more pronounced in the initial days following PRK. This procedure is considered more suitable for individuals with thinner corneas or those not ideal candidates for LASIK. Similar to LASIK, PRK can also be combined with monovision to address presbyopia.

Recovery and Healing

LASIK

  • Rapid vision improvement
  • Minimal discomfort
  • Return to work within 1-2 days

PRK

  • Gradual vision improvement
  • More initial discomfort
  • Full recovery in 1-4 weeks

LASIK vs PRK

Choosing the Right Procedure

Choosing between LASIK vs. PRK depends on various factors, including:

Corneal Thickness: People with thinner corneas may find PRK to be a suitable alternative to LASIK, offering comparable results while prioritizing safety.

Desired Recovery Time: LASIK offers quick recovery, allowing you to resume your normal activities sooner.

Lifestyle and Activities: Individuals with active lifestyles may prefer PRK as it offers long-term stability.

Discomfort Tolerance: PRK offers long-term benefits, and some people find the initial discomfort to be manageable and worth it for the long-term results.

Consultation is Key

Ultimately, discussing your vision correction options with an experienced LASIK surgeon is crucial for determining the best path forward. They will perform a comprehensive eye exam, consider your individual needs and goals, and recommend the most suitable procedure to achieve optimal results. This personalized approach ensures you receive the safest and most effective treatment for your unique circumstances.
