Visual Quality After Femtosecond Laser Small Incision Lenticule Extraction.

Femtosecond laser small incision lenticule extraction (SMILE) is a newly developed form of "flapless" corneal refractive surgery with all-in-one technology. Femtosecond laser SMILE is increasingly attractive for both doctors and patients because it is minimally invasive and does not require a flap to be lifted during surgery. It exhibits many advantages in terms of morphology, biomechanical effects, corneal wound healing, and nerve rehabilitation. However, visual quality assessment after refractive surgeries is just as important as these advantages and correlates with patient satisfaction. Evaluation indexes for visual quality include visual acuity, contrast sensitivity, aberration, intraocular scatterng, and so on. This paper reviewed visual quality and patient satisfaction after SMILE for myopia correction. Copyright 2017 Asia-Pacific Academy of Ophthalmology.
