LASIK vs. PRK: Key Differences and Similarities

When considering vision correction, LASIK (Laser-Assisted In Situ Keratomileusis) and PRK (Photorefractive Keratectomy) are two leading options that offer effective solutions for those seeking freedom from glasses or contact lenses. At Tyson Eye, under the expert care of Dr. Stephens, our cornea specialist, you can explore these advanced eye surgery options to find the best fit for your visual needs. Let’s delve into LASIK vs. PRK: key differences and similarities to help you make an informed decision.

What is LASIK?

LASIK eye surgery, also known as LASIK vision surgery, is a widely performed eye surgery designed to correct refractive errors such as nearsightedness, farsightedness, and astigmatism. The procedure involves creating a thin flap in the cornea using a microkeratome or femtosecond laser. This flap is then lifted to allow an excimer laser to reshape the underlying corneal tissue. After the cornea is reshaped, the flap is repositioned, serving as a natural bandage that promotes rapid healing.

Advantages of LASIK:

• Quick Recovery: Most patients experience improved vision within a day or two.
• Minimal Discomfort: Post-procedure discomfort is generally mild and brief.
• Does LASIK hurt:  The discomfort is typically minimal and short-lived.
• Precision: LASIK offers highly accurate and predictable outcomes.

LASIK Side Effects: While rare, potential side effects include dry eyes and visual disturbances.

What is PRK?

PRK eye surgery, or PRK vision surgery, is another laser eye surgery designed to correct refractive errors. Unlike LASIK, PRK does not involve creating a flap. Instead, the outer layer of the cornea, known as the epithelium, is gently removed to expose the corneal tissue. An excimer laser then reshapes the cornea to correct vision. The epithelium naturally regenerates over several days, during which a protective contact lens is used to aid in healing.

Advantages of PRK:

• No Flap Complications: Since PRK doesn’t involve creating a flap, there’s no risk of flap-related complications.
• Suitable for Thin Corneas: PRK is often recommended for patients with thinner corneas who may not be ideal candidates for LASIK.
• Proven Safety: PRK has been performed successfully for many years and is a well-established procedure.
• Does PRK hurt:  Patients may experience more discomfort during the initial healing phase due to the removal of the epithelium, but this typically subsides as healing progresses.

Key Differences Between LASIK and PRK

1. Procedure Technique:
   • LASIK: Involves creating a corneal flap and reshaping the underlying cornea.
   • PRK: Removes the outer corneal layer before reshaping the cornea.
2. Recovery Time:
   • LASIK: Patients usually experience quicker visual recovery, often within 24-48 hours.
   • PRK: The recovery period is longer, with visual improvement typically taking several days to weeks as the epithelium regenerates.
3. Discomfort Level:
   • LASIK: Discomfort is generally minimal and short-lived.
   • PRK: Patients may experience more discomfort during the initial healing phase.
4. Flap Complications:
   • LASIK: Risks include flap dislocation or complications.
   • PRK: No flap-related issues since the procedure does not involve creating a flap.
5. Corneal Thickness Requirements:
   • LASIK: Best suited for individuals with sufficient corneal thickness.
   • PRK: Better for those with thinner corneas.

Similarities Between LASIK and PRK

1. Laser Technology: Both procedures use an excimer laser to precisely reshape the cornea and correct vision errors.
2. Vision Correction: Both LASIK and PRK are effective in treating nearsightedness, farsightedness, and astigmatism.
3. Long-Term Results: Both procedures offer long-lasting vision correction with high patient satisfaction rates.
4. Outpatient Procedure: Both surgeries are performed on an outpatient basis, allowing you to return home the same day.
