If you rely on glasses or contacts, laser vision correction can open the door to clearer, more comfortable sight. The question is which option fits you best. LASIK, PRK, and SMILE are the most trusted choices, and each works a little differently.

How Laser Vision Correction Works

These procedures reshape the cornea so light focuses correctly. Your eye anatomy, prescription, and lifestyle guide which option is safest and most effective.

LASIK: Quick Recovery and Fast Results

LASIK is the most familiar and widely performed procedure.

How it works
A thin flap is created on the cornea, lifted, and the laser reshapes the tissue below. The flap is then placed back into position.

Why patients choose it

  • Clear vision within hours

  • Minimal irritation

  • Back to normal activities quickly

Good for Nearsightedness, farsightedness, and astigmatism.

PRK: Flap Free and Ideal for Active Lifestyles

PRK has been used for decades and delivers excellent long term clarity.

How it works
The surface layer of the cornea is removed. The laser reshapes the underlying tissue. The surface layer then grows back as you heal.

Why patients choose it

  • No flap

  • Works well for thinner corneas

  • Strong durability

Good for
Patients with high prescriptions or those at risk of eye injury, such as athletes or military members.

SMILE: A Gentle, Minimally Invasive Alternative

SMILE is newer and offers a precise, flap free approach.

How it works
A laser creates a tiny lens shaped piece of tissue inside the cornea. It is removed through a small opening, which reshapes the cornea.

Why patients choose it

  • Minimal disruption to the cornea

  • Quick healing

  • Very little irritation

Good for Nearsightedness and astigmatism.
