SMILE is a flap-less procedure, which means that all complications associated with corneal flap, as in the case of LASIK, would be excluded in SMILE. Retained part of the lenticule could happen in 3%, without significant visual compromise in most cases. If the visual outcome was suboptimal, further refractive surgery might be needed. Regression of shortsightedness could be encountered in 2% after the SMILE procedure, which might need further correction.
On the first day following SMILE procedure, 55% of the patients will achieve 20/20 vision. This percentage would increase to 93% by the end of the first month, and 96% by 3 months.
Like other laser refractive surgery patient should be 21 year-old and above
