Outcome of a Severe Blunt Trauma after SMILE (Small Incision Lenticule Extraction)

Introduction

ReLEx® is a common name of FLEx and SMILE operations for correction of vision which are performed exclusively using the VISUMAX® femtosecond laser (Carl Zeiss Meditec AG, Jena, Germany) without the use of an excimer laser. The first patient was operated in 2006 by Sekundo and Blum in Germany.

Femtosecond Lenticule Extraction (FLEx) which is completely FemtoLASIK [1] is a combination of femtosecond flap and femtosecond extraction of corneal optical lens (lenticule). Not requiring use of complex nomograms for calculations and energy testing like excimer laser, femtosecond laser makes the working process of a refractive surgeon easier. SMILE technology is initially wavefront-optimized as it weakly induces spherical aberration of the anterior cornea surface in the entire optic zone [2]. Besides, SMILE provides preservation of the corneal biomechanical stability unlike both FLEx and FemtoLASIK.
