SMILE: Minimally invasive Laser Vision Correction
Small Incision Lenticule Extraction, ReLEx, Refractive Lenticule Extraction, Minimal invasive LASIK
The SMILE Procedure
SMILE is a minimally invasive laser procedure using solely a femtosecond laser. The laser creates a refractive lenticule in the intact cornea as well as a small incision through which the lenticule is removed.
In a single step, the VisuMax creates a refractive lenticule and a small incision of less than 4 mm in the intact cornea - virtually regardless of the ambient conditions of corneal structure.
The lenticule is removed through the small incision. The disruption to the biomechanics of the cornea is minimal. No flap is cut.
The removal of the lenticule changes the form of the cornea, creating the required change to the refraction.
Advantages of SMILE
With less than 4 mm, the incision for lenticule extraction is 80% shorter and and the cap incision area up to 30% smaller than for a Femto-LASIK flap. This implies a smaller impact on the biostability of the cornea, a lower incidence of dry eye syndrome and a decreased risk of infections, epithelial ingrowths and flap complications.
