The ellipsoid method applied to two-dimensional B-mode ultrasound (Bmode-2D-US) is the most prevalent clinical approach, yet it is known to suffer from high observer dependence and limited accuracy.

PURPOSE: To compare the outcomes of enhancement after small incision lenticule extraction (SMILE) using surface ablation versus the VisuMax CIRCLE option (Carl Zeiss Meditec AG, Jena, Germany), which converts the SMILE cap into a femtosecond laser–assisted laser in situ keratomileusis flap.

With a reported incidence of 2.2%1 to 2.9%,2 enhancement rates after myopic small incision lenticule extraction (SMILE) seem to be comparable or slightly lower than those typically reported for LASIK.3–5 Although several reasons have been discussed for this fact, the lack of a flap to re-lift and the scarcity of data on safety and efficacy of re-treatment may be the main contributors.1,2 We have previously provided data on enhancement using surface ablation.1 Although this approach has been...
