A prospective Clinical trial involved 18 cases . The patients aged from 18 years old to 47 years old. Femtosecond laser small incision lenticule extraction (SMILE) was used to treat myopia from -3.5DS to -9.5DS with cylinder from -0.50DC to 3.50DC. The patients were followed up for more than 6 months with visual acuity, manifest refraction, intraocular pressure, wavefront aberration, corneal topography and optical coherence tomography (OCT). SPSS software was used to analysis.


SMILE procedure was done well in every patients without any scanning problem. No infection happened to in the trial. The patientsÂ’ UCVA improved to 0.8-1.2 . No eye lost BCVA. The difference between attempt and postoperative refraction was within ±0.5 0 DS. No epicenter showed in topography. Spherical aberration increased slightly . OCT showed the cap fit the stroma bed very well.


SMILE appears to be efficiency, safety and predictable for myopia. Its vision quality and wavefront aberration changes need to further investigation. FINANCIAL DISCLOSURE?: No
