[Clinical study of femtosecond laser corneal small incision lenticule extraction for correction of myopia and myopic astigmatism].

Objective: To evaluate the safety, efficacy, predictability, stability and complications of femtosecond laser corneal small incision lenticule extraction (SMILE) procedure for the correction of myopia and myopic astigmatism.

Methods: In this prospective study, 50 patients (88 eyes) with myopia and myopic astigmatism were chosen to be performed SMILE procedure randomly. These patients were followed up at 1 day, 1 week, 1 month and 3 months postoperatively and were examined for uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), manifest refraction, intraocular pressure (IOP) and corneal topography.
