PRK vs. LASIK: choosing the right eye surgery for you

Choosing to correct your vision with laser eye surgery is a major step toward visual freedom. But if you’re weighing your options between PRK and LASIK, it’s important to understand the differences between the two.

Both procedures are designed to reshape the cornea and correct common vision problems, including nearsightedness, farsightedness, and astigmatism. However, the way each surgery is performed, how quickly you recover, and whether you’re an ideal candidate can vary.

At LASIK Experts, our team in Philadelphia and New Jersey provides customized treatment recommendations based on your eye health, prescription, and lifestyle. Let’s explore the differences between PRK and LASIK so you can feel confident in your decision.

How does LASIK work?

LASIK (Laser-Assisted in Situ Keratomileusis) is the most commonly performed laser eye surgery, known for its typically quick recovery and long-term results. It’s an excellent option for those who want clearer vision with minimal downtime.

The LASIK process

1. A thin flap is created in the cornea using a femtosecond laser.
2. A specialized excimer laser reshapes the corneal tissue to correct vision.
3. The flap is repositioned, allowing for smooth healing without stitches. Since the corneal flap is preserved, the recovery is usually swift. Many patients experience clearer vision within a day.

Who’s a good candidate for LASIK?

• Adults 18 years or older with a stable prescription for at least 12 months.
• Individuals with adequate corneal thickness to support the flap.
• Those who prefer a quick recovery and minimal post-surgery discomfort.
• People with healthy eyes (free of conditions like keratoconus or severe dry eye).

How does PRK work?

PRK (Photorefractive Keratectomy) is another effective laser vision correction procedure, but unlike LASIK, it does not involve creating a corneal flap. Instead, PRK removes the outermost layer of the cornea (epithelium), allowing the laser to reshape the tissue directly. The epithelium then regrows over several days, making the recovery time slightly longer than LASIK.

The PRK process

1. The epithelial layer of the cornea is gently removed, exposing the corneal surface.
2. A precise laser reshapes the cornea, correcting refractive errors.
3. A protective contact lens is placed on the eye to aid in healing.

Because PRK does not require a corneal flap, it’s often recommended for patients who may not be ideal candidates for LASIK.

Who’s a good candidate for PRK?

• People with thin corneas who may not qualify for LASIK.
• Patients with chronic dry eye or irregular corneal structure.
• Individuals with active lifestyles or careers (e.g., military, law enforcement, high-impact sports) where a corneal flap could pose a risk.

Recovery after PRK vs. LASIK

One of the most significant differences between the procedures is how quickly patients tend to recover, as PRK tends to require a slightly longer healing time.

How long is the LASIK recovery?

• First 24 hours: Most patients recover within a day of LASIK and can return to normal activities quickly.
• First week: Some mild dryness or light sensitivity may occur but usually improves fast.
• Full recovery: Most LASIK patients have fully stabilized vision within a month.

How long is the PRK recovery?

• First few days: Blurry vision, light sensitivity, and discomfort are normal as the cornea heals.
• First week: Vision should become clearer, but some activities like driving may be challenging.
• Full recovery: It may take several weeks to months for vision to fully stabilize.

What’s the difference between LASIK and PRK?

PRK and LASIK are both highly effective laser vision correction procedures, but they differ in how they reshape the cornea, their recovery timelines, and who they’re best suited for. While both surgeries can help you achieve long-term visual freedom, understanding their unique features can help you determine the best choice for your lifestyle.

PRK and LASIK similarities

• Designed for vision correction – Both procedures address refractive errors like nearsightedness, farsightedness, and astigmatism.
• Advanced laser technology – Each surgery uses excimer lasers to reshape the cornea with precision.
• Quick and outpatient – The procedures take about 10-15 minutes, with patients returning home the same day.
• Long-term results – Most people achieve clearer, lasting vision and rely less (or not at all) on glasses or contacts.

PRK and LASIK differences

• Surgical approach – LASIK involves creating a corneal flap, while PRK removes the outermost corneal layer, which regenerates after surgery.
• Recovery speed – LASIK patients often see with clearer vision within a day, whereas PRK requires more healing time, with vision stabilizing over weeks or months.
• Best candidates – PRK is often recommended for individuals with thin corneas or those in active professions (e.g., military, law enforcement, sports), while LASIK is preferred by patients seeking fast recovery.
• Healing experience – PRK patients may feel more discomfort in the initial days, whereas LASIK has a quicker, more comfortable recovery.
