LASIK vs. PRK vs. SMILE: Which Procedure Fits Your Eyes?

Three proven procedures, different tradeoffs. Your cornea and goals determine the best fit.

Snapshot comparison

• LASIK: Flap created, then cornea reshaped; fast visual recovery; temporary dryness common.
• PRK: No flap—surface cells are removed, then treatment; slower recovery but good outcomes; useful for certain corneas.
• SMILE: Small incision removes a lenticule; no flap; limited to certain prescriptions; quick comfort, outcomes comparable in indicated cases.

Candidacy highlights

• LASIK: Needs adequate corneal thickness and regular maps. Broad prescription range.
• PRK: Considered when corneas are thinner or in cases where flap isn’t preferred.
• SMILE: Best evidence in myopia and myopic astigmatism within specific ranges; availability varies by clinic.

Recovery and comfort

• LASIK: Many people feel functional within 24–48 hours.
• PRK: Discomfort for several days; vision improves over 1–4 weeks.
• SMILE: Comfort is often good within days; visual recovery is typically quick.

Dry eye and night vision

All three can cause temporary dryness and night halos/glare early on. Experiences depend on your tear film, pupil size, and healing.

Cost and technology

Pricing reflects technology, surgeon experience, and your market. Not every clinic offers all three options. Ask which platform is recommended for you and why.

Which is right for me?

• Thin or borderline corneas: PRK is often preferred.
• High myopia within SMILE indications: SMILE may be an option where available.
• Broad candidacy and fast recovery: LASIK remains a strong choice for many patients.

Bottom line

Outcomes are excellent when the right procedure is chosen for the right eye. Let your screening data guide the decision with your surgeon.
