SMILE Software


Software module for Small Incision Lenticule Extraction

SMILE® from ZEISS enables the first Small Incision Lenticule Extraction procedure for minimally invasive laser vision correction. It offers a potentially lower incidence of transient dry eye syndrome and a wider preservation of biomechanical stability.

What is SMILE?

ZEISS SMILE is a game-changing software for laser vision correction that goes beyond PRK and LASIK and redefines refractive surgery. It is exclusively performed with the VisuMax® femtosecond laser from ZEISS.

  • Based on Nobel Prize-winning technology (Nobel Prize in Physics 2018)
  • Treatment planning and execution aided by a software wizard
  • Schematic visualization of cutting patterns during treatment planning

ZEISS SMILE provides an intuitive and easy-to-use treatment planning interface for Small Incision Lenticule Extraction.

Minimally invasive

With ZEISS SMILE, only a small incision of 2 mm is sufficient, meaning that the majority of the upper corneal layers remains untouched. The lamellar incision area is roughly 1/3 smaller than for Femto-LASIK treatment. What's more, the patient can usually return to their normal daily activities the next day.


ZEISS SMILE precalculates all intracorneal cuts necessary for the vision correction. The entire procedure is carried out in a single treatment process exclusively on the ZEISS VisuMax femtosecond laser.
