SMILE is a "keyhole" flapless procedure. A femtosecond laser creates a tiny, disc-shaped piece of tissue (a lenticule) inside the cornea that matches your prescription. The same laser then creates a very small (2-4mm) arc-shaped incision at the edge of the cornea. The surgeon gently removes the lenticule through this small incision. Removing this tissue reshapes the cornea, correcting nearsightedness. The procedure is quick, and the small incision seals itself without stitches.
Before procedure
Stop wearing contact lenses as directed by your surgeon (often 1 week for soft lenses, longer for hard/RGP lenses).
Arrange for transportation to and from the surgery center.
Avoid using eye makeup, creams, or perfumes on the day of surgery.
You will be prescribed antibiotic drops to start before surgery.
After procedure
Recovery is similar to LASIK but may be slightly more comfortable immediately after. Vision may be blurry or hazy for the first few hours.
Vision typically clears within 1-3 days.
Use all prescribed anti-inflammatory and antibiotic drops as directed.
Avoid rubbing your eyes and wear protective shields at night.
Dry eye symptoms are often less common and severe compared to LASIK.
Complication and alarm signs
Risks are low but can include under/overcorrection, dry eye (less common), infection (very rare), or difficulty removing the lenticule (requiring conversion to another procedure).
Contact your surgeon immediately if you experience: Severe pain, a sudden drop in vision, or signs of infection.
