Less laser energy improves lenticule surface during SMILE
Lowering femtosecond laser energy level to less than 115 nJ during small incision lenticule extraction can improve the surface quality of the lenticule, according to a study. Researchers investigated the effect of laser energy level on the surface of the lenticule for 40 age- and diopter-matched female patients with moderate myopia who underwent SMILE. The patients underwent the procedure with different energy levels between 100 nJ and 150 nJ along with fixed spot separation. Five lenticules from eight energy level groups were evaluated after the procedure.
