Comparing LASIK vs. PRK vs. SMILE

When it comes to laser vision correction, you’ve got more than one option. LASIK, PRK, and SMILE are all effective procedures—but they’re not one-size-fits-all.

At Elite LASIK & Cataract, we offer all three. Here’s how they compare—and how we help you choose the right one for your eyes.

What they all have in common

All three procedures:

• Use a laser to reshape your cornea
• Can correct short-sight, long-sight, and astigmatism
• Are done in just a few minutes
• Are safe, effective, and long-lasting.

The difference? How the laser reaches the cornea—and what that means for healing, comfort, and suitability.

LASIK

How it works:
A thin flap is made in the cornea. The laser reshapes the underlying layer. The flap is replaced and heals naturally.

Pros:

• Fast recovery (most people see well the next day)
• Minimal discomfort
• Proven, widely used

Best for:
People with healthy, thick corneas and stable prescriptions.

PRK (Photorefractive Keratectomy)

How it works:
No flap is made. Instead, the top layer of the cornea is gently removed. The laser reshapes the cornea underneath.

Pros:

• Good for thin corneas or dry eyes
• Less risk of flap complications
• Great long-term results.

Cons:

• Longer recovery (a few days to a week)
• More discomfort in the early days.

Best for:
People with thin corneas, active lifestyles, or higher risk of trauma to the eyes (e.g., athletes).

SMILE (Small Incision Lenticule Extraction)

How it works:
A laser creates a small disc of tissue inside the cornea, which is then removed through a tiny incision—no flap needed.

Pros:

• Minimally invasive
• Less dry eye
• Fast healing.

Cons:

• Only available for short-sightedness and some astigmatism
• Not ideal for long-sight or reading vision.

Best for:
People with mild to moderate myopia and those concerned about dry eyes or flap complications.

Which one is best?

There’s no one “best” procedure. It depends on:

• Your prescription
• Your corneal thickness
• Your lifestyle
• Your eye health
• Your recovery goals.

We do advanced scans and tests to guide you toward the safest, most effective option.

What if I’m not suitable for any of them?

If none of the laser options are suitable, we may recommend:

• Lens replacement
