Starting in 2006 a new "all femto" method of refractive correction for myopia and myopic astigmatism was introduced. This new method was originally introduced as femtosecond lenticule extraction (FLEx) and further developed with a small incision into SMILE (small incision lenticule extraction). To simplify the terminology the manufacturer brought this onto the market in April 2010 as ReLEx (refractive lenticule extraction). In this procedure a lenticule of intrastromal corneal tissue and a flap-like access cut are subsequently cut utilizing the VisuMax® femtosecond system (Carl Zeiss Meditec, Jena, Germany). The lenticule is then manually removed and the flap repositioned (only by FLEx). In approximately 1,000 successful surgical operations only few side effects were found. The number of eyes treated is currently being expanded in order to further standardize this new clinical procedure.
