QUICK ANSWER

What is SMILE LASIK?

SMILE LASIK is flapless laser vision correction: the ATOS femtosecond laser shapes a thin lenticule inside the cornea, which is removed through a small keyhole incision. Because no corneal flap is created, it is less invasive than traditional LASIK and has less impact on corneal nerves, reducing dry-eye symptoms. It corrects myopia and astigmatism.

CANDIDACY

Am I a candidate for SMILE LASIK?

SMILE LASIK suits people who:

  • Are over 18 with stable vision for at least one year
  • Have mild to moderate nearsightedness ( −1.00D to −10.00D) with or without astigmatism
  • Have healthy corneas with sufficient thickness
  • Do not have glaucoma or severe dry eye

Not the right fit? Compare options

Every eye is different. These alternatives may suit you better:

Farsighted (hyperopia)? See LASIK → Very high myopia? Consider ICL → Thin corneas? Consider LASEK → Over 40 with near-vision loss? See RLE →
