Understanding SMILE.

The latest advancement in the laser vision correction or near-sightedness and astigmatism, SMall Incision Lenticule Extraction (SMILE) offers the same accurate outcomes and rapid recovery as LASIK, but with additional advantages.

A femtosecond laser creates a thin corneal piece (lenticule) inside the cornea as well as a small incision. The surgeon removes the lenticule through the tiny opening which allows for the cornea to be reshaped. The major advantage of SMILE over LASIK is the lack of a flap. The least invasive refractive procedure in the world, SMILE leaves the surface of the cornea almost completely untouched allowing SMILE patients to benefit from less dry eye and more stable results over time.

Side effects of SMILE are mild and include temporary dry eyes, and foreign body sensation. Patients may experience nighttime glare or halo for a few days, which quickly resolves with normal healing. Complications of SMILE are extremely rare and are ALL treatable. These include infection, swelling or inflammation (diffuse lamellar keratitis).

Ideal candidates for SMILE are:

  • Under 45
  • Myopia (near-sightedness) up to -9.0D
  • Astigmatism up to 5.0D
  • Suitable corneal thickness
  • Contact sports
Surgery Length
  • 15 minutes
  • Local with oral sedation
Side Effects
  • Dry eyes
  • Irritation
  • Temporary night glare
  • Infection
  • Temporary swelling or inflammation
  • Discomfort 6‑12 hours
  • Vision 1‑2 days
  • Exercise 5‑7 days
  • Make up 7‑14 days
Final Visual Outcome
  • 1‑2 weeks
  • Dry eyes typically resolve in 4‑8 weeks
