PRK vs. LASIK: Which eye surgery is right for you?

If you're considering laser eye surgery, you’ve likely come across PRK vs. LASIK as two of the most common procedures. While both can correct nearsightedness, farsightedness, and astigmatism, they differ in technique, recovery time, and suitability for different patients.

Understanding the key differences between PRK and LASIK is essential in choosing the procedure that best fits your needs. This guide will break down how each surgery works, their pros and cons, how they fit into your lifestyle, and treatment options for people in Louisville, Indianapolis, and the surrounding areas.

What is LASIK?

LASIK (Laser-Assisted in Situ Keratomileusis) is the most well-known laser eye surgery because of its fast recovery time and high success rate.

How LASIK works

• A thin corneal flap is created using a precise laser.
• The underlying corneal tissue is reshaped using an excimer laser to correct nearsightedness, farsightedness, or astigmatism.
• The flap is gently repositioned, acting as a natural bandage to help healing.

Since the corneal flap remains intact, healing is usually quick. Most patients are back to their normal routine but with clearer vision in 24 hours.

Who’s the best candidate for LASIK?

• Patients should be at least 18 years old.
• People with healthy corneas and no history of severe dry eye.
• Those who want a fast recovery and minimal discomfort.

What is PRK?

PRK (Photorefractive Keratectomy) is an alternative form of laser eye surgery that doesn’t involve creating a flap. Instead, the procedure reshapes the cornea by removing the thin outer layer (epithelium), which regrows naturally over time.

How PRK works

• The epithelium is removed to expose the underlying cornea.
• A laser reshapes the corneal tissue to correct vision.
• A protective contact lens is placed over the eye to aid healing.

Since the epithelium must regenerate, PRK has a slightly longer recovery time than LASIK. Most patients see an improvement in their vision over several days to weeks.

Who’s the best candidate for PRK?

• People with thin corneas who aren’t candidates for LASIK.
• Individuals in physically demanding professions (e.g., military, law enforcement, contact sports) where a corneal flap might be at risk of displacement.
• Patients with chronic dry eye or certain corneal conditions.

Recovery time: What to expect

One of the biggest differences between PRK vs. LASIK is how long it takes to get back to your routine.

LASIK recovery

• Day After Surgery: Most patients wake up with clearer vision and are back in action the next day.
• First Week: Some mild eye dryness and halos around lights is normal but usually resolve quickly.
• Full Recovery: Within a month, vision should be completely stable.

At Greenberg LASIK, the majority of our patients are back to enjoying their regular activities within a day of LASIK.

PRK recovery

• First Few Days: Expect blurry vision, discomfort, and light sensitivity as the epithelium regrows.
• First Week: Vision should start to become clearer, but driving may not be possible yet.
• Full Recovery: It may take weeks to months for vision to fully stabilize.

PRK recovery takes longer, so outdoor activities should be postponed for a couple of weeks. But once your vision stabilizes, you’ll be able to get back to enjoying everything you love without the hassle of glasses and contacts.

PRK vs. LASIK: Similarities and differences

Both PRK and LASIK are laser vision correction procedures designed to correct vision by reshaping the cornea. While they share the same goal, they differ in technique, recovery, and suitability.

Similarities

• Correct the same vision problems: Both treat nearsightedness, farsightedness, and astigmatism.
• Use advanced laser technology: An excimer laser is used in both procedures to reshape the cornea.
• Quick procedures: Each surgery takes about 10-15 minutes.
• Long-term solution for clearer vision: Most PRK and LASIK patients achieve 20/20 vision or better, and experience clearer vision in the long-term.

Differences

• Surgical technique: LASIK involves creating a corneal flap, while PRK removes the outer corneal layer, which regenerates over time.
• Recovery time: LASIK patients are usually back to normal in 24 hours, while PRK recovery takes longer, with vision stabilizing over weeks.
• Best candidates: PRK is better for patients with thin corneas or those in high-impact professions, while LASIK is preferred for faster recovery.
• Post-surgery discomfort: PRK patients may experience more discomfort in the first few days compared to LASIK.

The bottom line: LASIK offers a quicker recovery, while PRK may be a better option for certain eye conditions or active lifestyles. Consulting with an experienced refractive surgeon can help determine the best choice.
