Effect of Lowering Laser Energy on the Surface Roughness of Human Corneal Lenticules in SMILE

Small incision lenticule extraction (SMILE) is the latest refractive surgical technique using only a femtosecond laser, which removes the corneal stromal lenticule through a small corneal incision ranging from 2 to 5 mm.1,2 This procedure could be achieved by using a femtosecond laser platform with higher firing frequency. Recently, the 500-kHz VisuMax (Carl Zeiss Meditec AG, Jena, Germany) platform with a pulse energy of 115 to 170 nJ has been used.1,3,4 Several studies have reported comparable or superior efficacy, predictability, and safety to other refractive surgery techniques, including
